Installing the complete prop shaft
Damage to the prop shaft during installation.
Non-observance of the installation guidelines for the prop shaft on the rear axle differential may cause severe damage.
- Always replace the recessed nut on the rear axle differential. Screw lock must be available.
- Strictly observe a minimum hardening time of three hours after having screwed in the recessed nut. The hardening time may be longer at lower temperatures.
- Observe following installation sequence:
- Position prop shaft on transmission.
- Position the prop shaft at the rear axle differential.
- Position central mount.
- Observe the following screwing sequence:
- recessed nut
- Flexible disc to transmission
