Tire Types

General information on wheel/tire combinations, winter tires, snow chain, recommended tire manufacturers. Refer to Wheel and Tire Guide.

Drive Axle General Information

Lightly coat the splines on the outer joint with assembly paste before installing the outer joint into the wheel hub. Refer to the Parts Catalog.

Do not let the drive axle hang down. The inner joint could be damaged if it is bent too far.

The wheel bearing must not be under load when the drive axle threaded connection on the wheel side is loose.

If the wheel bearings are loaded with the vehicle weight then the wheel bearing will be damaged. This reduces the service life of the wheel bearings. Observe the following when doing so:

  • Procedure for loosening drive axle to wheel hub bolted connection. Refer to → Chapter "Drive Axle Threaded Connection, Loosening and Tightening".

Vehicles without a drive axle must not be moved, otherwise the wheel bearing will be damaged. If the vehicle must be moved, be sure to note the following:

- Install an outer joint in place of the drive axle.

- Tighten the outer joint to 200 Nm.
