DRIVELINE, U-JOINT & CV AXLES REPLACEMENT PROCEDURES FOR 2008 Volkswagen GTI AUTOMOBILES
CV AXLE SHAFT, Replace
Vehicle: 2008 Volkswagen GTI 2.0 L4 GAS
Wheel bearing must not be burdened while 12 point nut is loose.
If wheel bearing is burdened by weight of vehicle, wheel bearing will be pre-damaged. This will diminish wheel bearing service life.
If it should be necessary to move a vehicle whose drive axle has been removed, before doing so install an outer joint in place of drive axle and tighten it to 11 ft. lbs., or else wheel bearing will be damaged.
The wheel hub/axle shaft on model "Golf GTI 132 kW" and R32 is secured with a hex bolt instead of a 12-point nut. The spline of outer joint is slightly shorter than previous...
