Strut leak

Struts are frequently rejected and exchanged because of leaks. Examinations on test stand and on the vehicle have shown that the replacement of a large number of rejected strut was not justified.

Slight leaking of oil ("sweating") at piston rod seal is no reason to replace a strut. A strut with oil is OK under the following circumstances

Scheme 7

Scheme 7: Strut leak
  1. Oil leak (shown screened in illustration) is visible, but dull, matte and possibly dry from dust
  2. Oil leak reaches at most, from upper shock absorber seal (piston rod seal) to lower spring plate - arrow -.

Note. A slight oil leak is advantageous because it lubricates the piston rod seal and extends its service life. This applies to struts on front and rear axles

Strut, noises

Struts are frequently rejected and exchanged because of rumbling noises. Examinations on the test stand and vehicle have shown that there was not a complaint with approx. 70% of the rejected shock absorbers and the replacement was not justified.

With complaints that are interpreted as rumbling or knocking sounds, proceed as follows.

  1. Determine on a road test with the customer - if possible on a dry stretch of road with irregularities - where, when and how these sounds change.

Note. In the rarest cases, the strut is the cause of the noises.

Strut, checking while removed

Faulty struts are noticeable when driving due to loud rumbling noises - a result of wheel hopping - especially on poor stretches of road. Moreover, they can be recognized by a large loss of oil.

Note. Struts are maintenance-free, shock absorber oil cannot be topped off.

A removed strut can be checked by hand as follows

  1. Press strut together by hand.
  1. Piston rods must move smoothly and with uniform difficulty over the entire range
  1. Release piston rods.
  1. On struts with sufficient gas pressure, piston rods return to initial position by themselves.

Note. If this is not the case, strut must be replaced. As long as there is no large loss of oil, the mode of operation corresponds to that of a conventional strut. The damping function is also completely available without gas pressure, as long as there is no large loss of oil. However, noise may increase.

Struts, testing on shock tester

Struts can be checked while installed using the shock tester (strut testing device). The damping effect can be evaluated based on the dial reading or print-out.

Special tools, testers and auxiliary items required

  1. Boge shock tester or
  2. Sachs shock tester V.A.G 1975 or
  3. Maha shock absorber tester VAS 1990

Note. Temperature +10 to +40°C. Driver in vehicle. Tire pressure OK. Drive vehicle straight onto center of wheel contact plates. Front wheels in straight position. Parking not engaged, foot brake not activated.

Threshold

Strut condition can only be judged as follows

  1. Sufficient damping effect

or

  1. Insufficient damping effect

Note. Intermediate values for reduced damping performance cannot be read out. A prognosis on service life is not permitted. Measured values that come about from involvement of suspension travel end stops are incorrect.

The following values apply only to the test stands named above. If the specified values are exceeded, the strut action has weakened enough that a replacement is recommended.

Damaged threads, repairing

Damaged threads can be repaired with wire inserts (Heli-Coil).

See component overviews to learn which threads can be repaired.

Shavings that remain in the body must be imbedded in wax.

Longmember thread, servicing

It is possible to service the threads of weld nuts in longitudinal member depending on certain conditions.

  1. Servicing work may only be performed once per thread.
  2. If servicing is necessary after this, the nuts must be replaced.
CAUTIONWhen drilling, it is essential that eye protection be worn!
  1. Have thread repair checked by the responsible foreman or next person in charge.
  2. Thread insert must be same length as thread in body.
  3. Correct any damage to the underbody sealant layer.

General Information

When installing waxed components, contact surfaces must be cleaned. Contact surfaces must be free of wax and grease.

Torque specifications for unoiled bolts and nuts are given.

Welding or straightening operations are not permitted on load-bearing or wheel-controlling components.

Always avoid the following actions with coil springs: Hammer stroke, welding beads, applying color identification later.

Do not perform any welding or grinding (separating work) in coil spring or suspension strut area! Cover coil spring or suspension struts if necessary.

Vehicles without drive axle must not be moved, otherwise wheel bearing will be damaged. If vehicle must be moved, observe the following

  1. Install an outer joint in place of the drive axle.
  2. Tighten outer joint to 115 Nm (screw M14) or 200 Nm (screw M16).

Bonded rubber bushings have a limited torsional range. Only tighten threaded connections at control arms if vehicle is in curb weight position --> Wheel bearing, lifting to curb weight position

If the vehicle must still be aligned, every bolt and nut that must be loosened for adjustment is only tightened to torque specification. After measurement/adjustment is complete, tighten bolts and nuts to prescribed additional torque angle.

CAUTIONIf vehicle will be driving on the streets, all bolts and nuts must be tightened properly!

Scheme 9

Scheme 9: Wheel bearing, lifting to curb weight position

Special tools, testers and auxiliary items required

  1. Engine/transmission jack V.A.G 1383 A
  2. Tensioning Strap T10038
  3. Wheel hub support T10149

Note. All bolts at suspension parts with bonded rubber bushings must always be tightened in curb weight position (unloaded condition).

Bonded rubber bushings have a limited torsional range.

Parts with bonded rubber bushings must be brought into a position that corresponds to the position in driving mode before being tightened (curb weight position)

Otherwise, bonded rubber bushing will be stressed resulting in a shortened service life.

By raising appropriate suspension using engine/transmission jack V.A.G 1383 A and Wheel Hub Support T10149 , this position can be simulated on the hoist.

Scheme 10

Scheme 10
  1. Before starting work, take measurement - a - , e.g. with tape measure, from center of wheel to lower edge of wheelhouse.

The measurement must be taken in curb weight position (unloaded).

  1. Make a note of the measurement. It will be needed for tightening the bolts/nuts.

Before appropriate suspension is raised, vehicle must be strapped to lift arms of hoist using tensioning straps T10038.

If a vehicle is not secured, there is danger that the vehicle could slip off the lift!

  1. Turn wheel hub until one of the holes for the wheel bolts is at the 12 o'clock position.
  2. Install wheel hub support T10149 with wheel bolt on wheel hub.

Scheme 11

Scheme 11
  1. Using engine/transmission jack V.A.G 1383 A , lift wheel bearing housing until dimension - a - is reached.

Tightening of the respective bolts/nuts must then only occur after dimension - a - , which was measured before installation between the wheel hub center and the lower edge of wheelhousing, has been attained

CAUTIONDo not lift or lower vehicle with engine/transmission jack below vehicle. Do not leave engine/transmission jack V.A.G 1383 A below vehicle any longer than necessary.
  1. Tighten respective bolts/nuts.
  2. Lower steering knuckle.
  3. Move engine/transmission jack away from under vehicle.
  4. Remove wheel hub support T10149.

  2. 94 LIGHTS, SWITCHES - EXTERIOR for ELECTRICAL EQUIPMENT, CABRIOLET

To function properly, the automatic vertical aim control system needs information about compression travel or rebound travel at the front and rear axles.

For this, the position of the lower left link relative to the body is transferred to Left Front Level Control System Sensor G78 via a coupling rod. This transmits electrical signals to the Headlamp Range Control Module J431.

Headlamp Range Control Module J431 -->

On the rear axle, the signals are transmitted to Headlamp Range Control Module J431 from G76 Left Rear Level Control System Sensor G76.

These signals are required for determining vehicle level.

The automatic headlight range control reacts independently to changes in vehicle level.

The vehicle level can change in the following situations

  1. Towing a trailer
  2. Different load conditions; vehicle empty, vehicle partially or fully loaded
  3. Slow or fast driving habit
CAUTIONAdjustment of headlights!

Bonded rubber bushings have a limited torsional range.

Parts with bonded rubber bushings must be brought into a position that corresponds to the position in driving mode before being tightened (curb weight position)

Otherwise, bonded rubber bushing will be stressed resulting in a shortened service life.

By raising appropriate suspension using engine/transmission jack V.A.G 1383 A and Wheel Hub Support T10149 , this position can be simulated on hoist.

  1. Before starting work, take measurement - a - , e.g. with tape measure, from center of wheel to lower edge of wheelhousing.

The measurement must be taken in curb weight position (unloaded).

  1. Make a note of measurement. It will be needed for tightening bolts/nuts.

Before appropriate suspension is raised, vehicle must be strapped to lift arms of hoist using tensioning straps T10038.

If a vehicle is not secured, there is danger that the vehicle could slip off the lift!

  1. Turn wheel hub until one of the holes for the wheel bolts is at the 12 o'clock position.
  2. Install wheel hub support T10149 with wheel bolt on wheel hub.
  1. Using engine/transmission jack V.A.G 1383 A , lift wheel bearing housing until dimension - a - is reached.

Tightening of the respective bolts/nuts must then only occur after dimension - a - , which was measured before installation between the wheel hub center and the lower edge of wheelhousing, has been attained

CAUTIONDo not lift or lower vehicle with engine/transmission jack below vehicle. Do not leave engine/transmission jack V.A.G 1383 A below vehicle any longer than necessary.
  1. Tighten respective bolts/nuts.

  2. Tilt hub out of cage.

Checking

6 balls for each joint belong to a tolerance group. Check stub axle, hub, cage and balls for small indentations (pitting) and signs of seizure. Excessive backlash in the joint will cause knocking or jolts under load change. In such cases joint should be replaced. Flattening and running marks of balls are no reason to replace joint.

Assembling

  1. Press quantity of grease into joint body «Grease quantity and type»(/audi/a4/b7-2004-2009/remont/axle-shafts/#suspension-wheels-steering) (100 mm dia.) or «Grease quantity and type»(/audi/a4/b7-2004-2009/remont/axle-shafts/#suspension-wheels-steering) (108 mm dia.), grease quantity and type.
  2. Install cage with hub in the joint housing.

Note. Cage must be installed laterally correct.

  1. Press in opposing balls in sequence, during this, previous position of ball hub to ball cage and to joint body must be re-established.

In order to replace grease in case of strong soiling, joint must be disassembled and if journal surfaces and balls must be checked for wear and damage.

Note. Ball hub and joint are paired and should be identified before removal. Do not interchange cage allocation.

  1. Swing ball hub and ball cage and pull out of joint in direction of - arrow -.
  2. Press balls out of cage.
  1. Flip out ball hub from ball cage via running path of ball - arrows -.

Checking

  1. Check joint housing, ball hub, ball cage and balls for indentations (pitting) and signs of seizure.

Note. Excessive backlash in the joint will cause knocking or jolts under load change. In such cases the joint must be replaced. Flattening and running marks of balls are no reason to replace joint.

Assembling

  1. Press quantity of grease into joint body «Grease quantity and type»(/audi/a4/b7-2004-2009/remont/axle-shafts/#suspension-wheels-steering) (100 mm dia.) or «Grease quantity and type»(/audi/a4/b7-2004-2009/remont/axle-shafts/#suspension-wheels-steering) (108 mm dia.), grease quantity and type.
  1. Insert ball hub into ball cage via two chamfers. The hub can be installed in any position. Press balls into cage.
  2. Insert hub with cage and balls at right angle to the joint.

Note. When inserting make sure that the wide space - a - on joint housing is aligned with the narrow space - b - on the hub after swiveling in.

  1. Install ball hub, whereby the hub must be swiveled out of cage - arrows - far enough to allow balls to fit into ball tracks.
  1. Press cage firmly - arrow - until hub swings fully in position.

Constant velocity joint, checking for function

Constant velocity joint is properly assembled, if ball hub can be slid back and forth by hand over whole compensation length.

Only approved oil should be used for filling or topping off.

To attach or detach charging device V.A.S 6209/2 , system line to be checked must be locked at central valve to limit the quantity of oil leaked to a minimum and to prevent pressurized central valve from emptying.

Before removal or separation, the corresponding line for every DRC component is to be locked at central valve. If work on DRC with unlocked central valve results in even a small amount of oil, a system pressure check with comparison to specified values must be performed in every case. If minimum pressure is not met, central valve must be replaced.

Small oil leak with locked central valve which results from connecting or disconnected charging device V.A.S 6209/2 at connection is not critical. Avoid repeating measurements because a small quantity of oil is removed from the system every time V.A.S 6209/2 is connected. Every connection results in a pressure decrease of approx. 0.3 bar from the previous reading. In this way, multiple repeats of measurements cause pressure to fall below minimum level or malfunction.

Dampers and lines are delivered empty as replacement parts.

Filling must only be done at room temperature (approx. 20° Celsius).

Dampers must only be filled when installed.

Vehicle must never be placed on wheels with closed, filled system and locked central valves. This inevitably leads to leaks and system malfunction.

Lines must not be bent.

Wheels, tires

This information is contained in AESIS; Library; Additional Information; Wheels and Tire Guide

Observe notes about usage in your Owners Manual.

Damaged wheel electronics or valves should be replaced for safety reasons.

Do not clean wheel electronics with steam blasting or strong compressed air.

Replace wheel electronics after using tire sealant as the accumulation of sealant on the pressure sensor can cause false readings.

The Tire Pressure Monitoring System monitors the pressure of the 4 tires while driving.

If wheel positions on vehicle are changed or wheels or wheel sensors replaced, this must be confirmed using the steering column or the control module in the center console. Finally, the system has to relearn the wheel sensors.

Note. When changing wheels with wheel electronics (summer/winter tires), pressure must be checked and control module must relearn wheel electronics.

A fault may be saved in the DTC memory if

Less than three wheels with wheel electronics are installed.

Winter tires without wheel electronics are installed. (If this is the case, the yellow warning lamp in instrument cluster is set and cannot be deactivated by the system.)

Front axle toe-in curve, adjusting

Explanation

When the wheel compresses or rebounds, the wheel s toe changes as a function of the compression and rebound travel. The resulting toe measurements are described as the toe curve.

The change in the toe constants "S" is adjusted when the vehicle is raised by vertically shifting the tie rod end --> Toe constant "S" , adjusting

The wheel alignment computer determines the toe constant "S" using values measured in the initial and raised positions. The computer compares the measured values with the specifications and displays them on the screen.

Depending on the suspension, various adapters are necessary for raising the vehicle --> Application of adapters to suspension for measurement .

Note. An incorrectly adjusting toe constant causes vehicle to turn when braking/accelerating or when driving over bumps.

Vehicle, bringing into initial position for measurement

Note. Fluid must be drawn off if the level is above the specified range. If oil level is below aforementioned area, then the hydraulic system must be checked for leaks. It is not sufficient to merely top off the fluid. Do not use drained hydraulic oil.

Steering system, bleeding after reconstructing

After steering system reconstruction, system must be bled differently depending on extent of reconstruction.

After exchanging entire steering system or exchanging steering gear

  1. Check hydraulic fluid level and top off if necessary.
  2. Raise vehicle until front wheels are off the ground.
  3. Briefly start engine (max. 2 sec.)

Pump must not draw in any air and steering wheel must not be turned under any circumstances.

Any remaining air in steering system will dissipate by itself when driving over the next 10 to 20 km.

When reconstruction a component of the steering system besides the steering gear (pump, hoses, etc. )

  1. Check hydraulic fluid level and top off if necessary.
  2. Briefly start engine (max. 2 sec.)

Pump must not draw in any air and steering wheel must not be turned under any circumstances.

Approx. 30 sec. wait between individual engine starts.

  1. Check hydraulic fluid level and top off if necessary.
  2. Repeat this process until oil level remains constant.
  3. Start engine and allow to run 2 - 3 minutes, do not turn steering wheel.

Any remaining air in steering system will dissipate by itself when driving over the next 10 to 20 km.

Steering system, checking for leaks

Note. Following installation operations and with no hydraulic fluid in the expansion tank, the steering system must be checked for leaks.

  1. Start engine.
  2. Turn steering wheel in both directions to full lock and hold briefly. This builds up the maximum possible pressure.

To avoid damage to pump, steering wheel must not be held at stop longer than 10 seconds during this test.

In this position, the following components must be checked for leaks.

  1. Seal ring for steering pinion at steering gear valve housing.
  2. All line connections
  3. Rack sealing rings

This test can only be performed with boots slid back.

  1. Open boot spring hose clamp and ear hose clamp.
  2. Slide boot back.

If fluid is visible in steering gear housing and/or in boots, steering gear must be replaced.

Vehicles with 4-cylinder engines, assembly overview

There is no provision for servicing the power steering pump. If there are customer complaints, the cause must be determined using a pressure and leak test. If a malfunction is present, the power steering pump must be replaced.

Note. If the fluid level in the reservoir is low, the steering system must be inspected for leaks. If there are leaks in the area of the line connections, the lines/connections must first be inspected for leaks, tightened as necessary and wiped dry. Pumps from service parts inventory do not contain fluid. They must be filled with hydraulic fluid before installation and turned by hand, otherwise pump noise or damage can result in operation.
