- Install circlip.

Audi Q3. V40-0003

- Apply sealant -hatched surface- to clean surface on inner side of protective joint boot cap. Continuous sealant bead: Diameter 2 to 3 mm skirt area around inner holes -arrow-.

- Use sealant. Refer to the Parts Catalog.

- Slide the CV boot onto drive axle.

The drive axle, CV boot and cap contact surfaces must be free of grease.

Make sure you do not damage the sealant bead.

Audi Q3. A42-0277

- Using screws -arrows-, align protective boot and cap with screw holes.

It must be aligned exactly because it cannot be aligned after driving on.

Stainless steel clamps for Hytrel protective joint boots, tensioning

- Position pliers VAG1682 as shown in illustration. When doing this, make sure that edges of clamping pliers are seated in corners -arrows B- of clamp.

- Tighten the hose clamp by turning spindle -A- using a torque wrench (do not tilt clamping pliers).

  • Tightening specification: 20 Nm

  Note

  • Make sure the threads on the spindle on the pliers move easily. Lubricate with MoS2 grease, if necessary.
  • If the thread is tight, for example, dirty, the required tensioning force for the hose clamp will not be achieved in spite of correct torque specification settings.

Disassembling

Outer CV joint, pressing off

- Clamp the drive axle with protective jaws in a vise clamp.

- Fold back boot.

- Drive CV joint from drive axle using a drift -A-.

The drift must be installed exactly on the CV joint ball hub.

Driving joint on

- Drive onto shaft with plastic hammer until the circlip engages.

Audi Q3. N42-10335

Removing the inner CV joint

- Press off the CV boot from joint using drift.

- Remove the circlip.

- Remove both clamps, and push the CV boot toward outer joint.

Audi Q3. N40-0482

Tightening clamping sleeve on outer joint

- Attach the Clamping Pliers -VAG1682A- as illustrated. When doing this, make sure that edges of clamping pliers are seated in corners -arrows B- of clamp.

- Tension clamp by turning spindle with a torque wrench (do not tilt clamp tool).

  Note

  • The hard material of the CV boot (compared to rubber) makes it necessary to use a stainless steel hose clamp. It is only possible to tighten the hose clamp with Clamping Pliers -VAG1682A-.
  • Tightening specification: 25 Nm.
  • Use torque wrench -C- with adjustment range 5...50 Nm (for example Torque Wrench 1331 5-50Nm -VAG1331-).
  • Make sure the threads on the spindle -A- on the pliers move easily. Lubricate with MOS 2 grease, if necessary.
  • If the thread is tight, for example, dirty, the required tensioning force for the hose clamp will not be achieved in spite of correct torque specification settings.
