General Repair Notes

The maximum possible care, cleanliness and proper tools are essential to ensure satisfactory and successful transmission repairs. The usual basic safety precautions also apply when carrying out vehicle repairs.

A number of generally applicable instructions for individual repair procedures, which are otherwise mentioned at various points in the article, are summarized under the term "components" --> Components . They apply to this article.

Vehicle jack mode on vehicles with air spring suspension

Before raising a vehicle with air spring suspension on a 2-pillar lifting platform (wheels off the ground), first activate the vehicle jack mode --> 43 - SELF LEVELING SUSPENSION .

  1. Allocate bolts and other components according to the Final Drive code via Electronic Parts Catalog (ETKA).
  2. When replacing rear final drive, check and if necessary, correct oil level in final drive --> «Axle oil in rear final drive, checking»(/audi/a6/6-2004-2008/remont/differentials-drive-axles/#rear-final-drive-0ar) .

  4. Clean contact surfaces when repairing mounting brackets and waxed components. Contact surfaces must be completely free of oil and grease.
  1. Thoroughly clean all connections and surrounding area before disconnecting.

O-rings, gaskets, seals

  1. Always replace O-rings, gaskets and seals.
  2. After removing gaskets and seals, always inspect the contact surfaces at housing or shaft for burrs resulting from removal, or for other signs of damage.
  3. Thoroughly clean housing joint surfaces before assembling.

Scheme 106

Scheme 106
Scheme 106
  1. Before installing, lightly oil outer circumference of radial-shaft seals and fill gap between sealing lips - arrow - half way with sealing grease G 052 128 A1 .
  2. The open side of the gaskets points toward the fluid to be sealed in.
  3. Lightly lubricate O-rings before installing, this prevents the rings from being pinched when inserting.
  4. Check transmission oil level after replacing gaskets and seals --> «Axle oil in rear final drive, checking»(/audi/a6/6-2004-2008/remont/differentials-drive-axles/#rear-final-drive-0ar) .

Securing rings

  1. Do not over-stretch circlips.
  2. Always replace damaged or over-stretched circlips.
  3. Securing rings must be fully seated in groove.

Scheme 107

Scheme 107
Scheme 107
  1. Replace roll pins. Installation position: Slot - A - is longitudinal to line of force - arrow -.

Nuts, bolts

  1. Loosen and tighten bolts or nuts for securing covers and housings in diagonal sequence.
  2. Do not cant, rather loosen and tighten especially sensitive parts in diagonal manner in stages.
  3. The tightening torques stated apply to non-oiled nuts and bolts.
  4. Always replace self-locking nuts and bolts.
  1. Using a wire brush, clean threads of bolts (replace outer driveshaft bolts) which are secured with locking compound. Then insert bolts with locking fluid AMV 185 101 A1 .
  2. Threaded bores into which self-locking bolts or bolts with locking compound were threaded in, must be cleaned (e.g. using threaded tap). Otherwise there is the danger that the bolts may shear when removed again.

Driveshaft, servicing overview

Note. Observe general repair notes --> General Repair Notes . No repair work can be performed on the driveshaft - with the exception of removing and installing and adjustment work. Always store and transport driveshaft fully extended only. Driveshaft can be bent without force up to the center joint stop. A hard bending to the stop may cause damage to the center joint or dust boot. If the driveshaft is only detached at the transmission or from rear final drive, it should be tied up or supported at the shaft end. Driveshaft must also bend without force up to the center joint stop. Mark positions of all parts to each other before removing. Reinstall in identical position otherwise imbalance will be too high which could result in damage to the bearing or in vibration noises. Driveshaft bolts are loosened and tightened with the parking brake engaged. After disconnecting driveshaft from rear final drive, an installed balance washer (thick washer between backing plate and hex socket head bolt) may not be reinstalled. For complaints (noise, vibrations), check intermediate bearing for freedom from tension and radial run-out of driveshaft flange at rear final drive before replacing the driveshaft --> Measure radial play at flange/driveshaft and mark .

Driveshaft, securing to rear final drive

Installation is in reverse order of removal. Note the following

  1. Remove old and dry high-temperature grease from CV joint and flange for driveshaft. Fill the exact same amount of new grease G 000 633.
  2. Threaded holes in flange shaft at rear final drive must be cleaned of locking compound residue. Cleaning can be performed with a tap. Otherwise, the securing bolts can shear while installing.
  3. After disconnecting driveshaft from rear final drive, an additional balance washer (thick washer) that may be located between shim and a mounting bolt may not be reinstalled.
  4. Always replace (self-locking) securing bolts for driveshaft.
  1. Replace seal for driveshaft at rear final drive flange. Remove grease from sealing surfaces and adhere new seal.
  2. Insert driveshaft and install bolts for CV joint.
  1. Make sure that the markings on flange for driveshaft - arrow A - and for rear final drive - arrow B - line up.

Scheme 133: Measure radial play at flange/driveshaft and mark
  1. Dial gauge holder VW 387
  2. Dial gauge
  3. Bolt M10x30

Note. Radial run-out must always be measured if the flange/driveshaft at rear final drive was removed. For this, make new color marking and remove old color marking. If a new driveshaft is installed and the color marking on the drive flange of the rear final drive is no longer visible, location of largest radial run-out (corresponding to greatest distance from turning axis) must be determined and marked with a color marking. This color marking - arrow A - is set opposite the color marking on the driveshaft - arrow B -. Radial run-out can be measured with rear final drive installed.

  1. Remove driveshaft from rear final drive --> «Driveshaft, disconnecting from rear final drive»(/audi/a6/6-2004-2008/remont/differentials-drive-axles/#rear-final-drive-0ar__driveshaft-disconnecting-from-rear-final-drive) .
