Rear wheel roller bearing - check and adjust clearance — VW

🧭 Before you start

Fits: VW Fox (5Z)

Don't miss

• The play adjustment is correct when it is possible to displace the thrust washer in only the radial direction and, when moving the brake drum in the axial direction, it does not have an apparent play.
• The wheel hub cover must be replaced whenever removed

📋 Procedure

1. Remove the wheel hub protector (4), with the Hub nut protector pullerVW 637/2.
2. Remove the cotter pin (5) and the sprocket (3).
3. Place a screwdriver between the washer and the brake drum hub so the screwdriver is perpendicular to the washer.
4. Move the washer in the radial direction with a light pressure of the forefinger(arrow) applied to the end of the screwdriver.
5. Never turn (arrows) or leverage the screwdriver. [Note: The play adjustment is correct when it is possible to displace the thrust washer in only the radial direction and, when moving the brake drum in the axial direction, it does not have an apparent play.]

6. If the washer does not move, it is necessary to adjust the roller bearing clearance.
7. ⚠ The screwdriver should touch only the washer and never the outer roller bearing of the wheel. Never rotate or leverage with the screwdriver, assuring that the screwdriver does not touch the brake drum hub on no account. If the notes above are not strictly followed, the adjustment of bearing end play will be jeopardized (it can lead to noises and breakage of bearings). — Loosen or tighten the hexagonal nut, relieving or increasing the pressure on the thrust washer and, simultaneously, check its movement in the radial direction, according to the procedure described above.
8. Check the roller bearing clearance adjustment again. If necessary, repeat the procedure until the adjustment is correct (see the separate procedure).
9. Install the sprocket.
10. Install the new cotter pin.
11. Install the new wheel hub protector with the Support tube40-21. [Note: The wheel hub cover must be replaced whenever removed]
12. Install and tighten wheel securing bolts. Tightening torque, see (see the separate procedure).
