FASTENER TIGHTENING SPECIFICATIONS

OUTER CV JOINT, CHECKING

It is necessary to disassemble the joint whenever replacing the grease or if the ball surfaces show wear or damage.

Disassembling

Scheme 214

Mark position of the ball hub to ball cage and to housing before disassembling, using electro-writer or grindstone.

Swivel the ball hub and ball cage.

Remove the balls one after the other.

Turn cage, until two rectangular windows -arrow- contact joint body.

Scheme 215

Lift out cage with hub.

Swing hub segment with smaller pins into rectangular window on cage.

Scheme 216

Fold hub out from cage.

Checking

6 balls for each joint belong to a tolerance group. Check stub axle, hub, cage and balls for small depressions (pitting build-up) and chafing. Excessive circumferential backlash in joint makes itself noticed via tip-in shock, in such cases joint should be replaced. Flattening and running marks of balls are no reason to replace joint.

Assembling

LEVEL CONTROL SYSTEM SENSOR

General Information

Vehicles with electronically controlled damping and/or HID headlamps have standard automatic headlamp range control. Refer to Description and Operation .

To function properly, the electronically controlled damping and automatic headlamp range control system need information about compression travel or rebound travel at the front and rear axles.

For this, the position of the left/right trapezoidal arm in relation to the body is transferred via a coupling rod to left rear level control system sensor -G76- and right rear level control system sensor -G77-. These transmit electrical signals to the electronic damping control module -J250- and/or left/right HID gas discharge lamp control module -J343/344-.

Left/right HID gas discharge lamp control module --, servicing Description and Operation .

At the front axle, these signals are transmitted from the left front level control system sensor -G78- and right front level control sensor -G289- to the and/or the left/right HID gas discharge lamp control module --.

These signals are required for determining vehicle level.

The headlamp range control responds automatically to changes in the vehicle level.

The vehicle level can change in the following situations

1. Trailer Mode
2. Different load conditions; vehicle empty, vehicle partially or fully loaded

Note. Programming the control position and checking the headlamp basic setting is necessary on vehicles with electronically controlled damping if

3. Use torque wrench with 5 to 50 Nm range (for example V.A.G 1331).
4. Make sure the spindle threads on the pliers -A- move freely. Grease with MoS 2 grease if necessary.
5. If the thread is tight for example dirty, the required tensioning force for the hose clamp will not be achieved in spite of correct tightening specification settings.

Mount and Tension the Clamp with the Retaining Tabs using 3340 as Illustrated.

Engage the clamp at the first catch by hand.

Close the clamp using 3340.
