Rear Suspension

Removing and installing rear wheel bearing











Information

Information
The wheel bearings adopt the function of the former ABS pulse rings. They are fitted with a so-called multipole seal. This is a seal with a magnetized layer, which generates the torque impulses for the ABS rpm sensors.

The multipole seal must not come into contact with highly magnetic parts. During installation, make sure that the magnetic side is facing the ABS sensor. Use test card 147.2 for this.





Preliminary work

1. Remove rear wheel bearing housing (wheel carrier).
2. Remove brake disc, parking-brake shoes, brake cover plate and speed sensor on wheel bearing housing (wheel carrier).

Removing rear wheel bearing

1. Press out wheel hub.





Pressing out wheel hub

Press the wheel hub out using press-out mandrel P 297a.
Separating device ([diameter] = 12 - 115 mm) NR.111 and a suitable support must be used for countering.

2. Remove bearing cover.





Removing bearing cover

Unscrew screws -1- and remove bearing cover -2-.

3. Heat wheel bearing housing to approx. 100 °C (max. 120 °C).

Warning
Hot wheel bearing housing!
Danger of burns

- Wear heat-resistant gloves!

4. Press out wheel bearing using a tube VW 415 A.





Pressing out wheel bearing

5. Press out wheel bearing inner ring.





Pressing out bearing ring

Use a two-claw puller together with a suitable intermediate piece (e.g. pressure piece VW 433 ) to pull the inner bearing ring several millimeters off the wheel hub.

Press out inner bearing ring using a press-out mandrel P 297a together with the separating device ([diameter] = 12 - 115 mm) NR.111.

1. Fit (press in) wheel bearing at the correct position.

Before installation, clean the bore in the wheel bearing housing and remove edges with a polishing cloth.

Heat up wheel bearing housing before pressing in the wheel bearing.





Pressing in wheel bearing

Preparatory condition: - Temperature: 100°C+20°C

Fit wheel bearing at the correct position. Then press again on the wheel bearing housing with only slight force using a suitable pressure piece -2- (9247/3), see pressure pieces (4 x) P 9247 and -1- tube VW 415 A.

Warning
Hot wheel bearing housing!
Danger of burns

- Wear heat-resistant gloves!

2. Install bearing cover -2-. (arrow = cut-out for water drain)





Installing bearing cover

Screw in and tighten screws -1-. - Tightening torque: 37 Nm (27 ftlb.)

3. Press in wheel hub.





Pressing in wheel hub

Position wheel bearing housing on wheel hub and press on wheel bearing inner ring using a tube VW 415 A.

Subsequent work

1. Install rear wheel bearing housing (wheel carrier).
2. Fit brake disc, parking-brake shoes, brake cover plate and speed sensor on wheel bearing housing (wheel carrier). Observe correct tightening torques.
