Raise and support the vehicle.
Completely remove the exhaust system.
Loosen the bolts and remove the heat shields (1) And (2) bottoms.
Unscrew the bolts and remove the coupling from the gearbox. The cardan shaft must be held in place with a suitable strap wrench to prevent the shaft from turning.
Unscrew the nuts securing the driveshaft to the rear axle flange.
Press the CV joint along the grooves of the flange with a screwdriver.
Holding down the middle (reference) bearing, unscrew the nuts.
Tilt the cardan shaft at the middle support down and pull it out of the centering pins on the gearbox.
Attention: The CV joint of the cardan shaft must be protected from contamination with a plastic bag.
Installation
With vibrations and noises that come from the cardan shaft, it must be balanced in the workshop. In addition, you need to check if the hinges are damaged.
Attention: The cardan shaft is balanced at the factory and should only be replaced as a complete assembly. Replace worn driveshaft.
Replace the coupling when it is worn out by unscrewing the bolts (arrows). Install the new coupling so that the arrows on the circumference point towards the flange levers.
Before installing, check the centering of the cardan shaft (4) on the coupling, lubricate the centering element with grease if necessary. Replace damaged centering element.
Pull out the CV joint (1) all the way. Fill the CV joint with grease when the grease is used up or lost. Use only special grease.
Replace gasket (2). Before doing this, degrease the sealing surfaces on the CV joint and on the drive flange with alcohol.
Slide the driveshaft with the CV joint tightened onto the rear axle flange.
Attention: Those and it should not be compressed during installation, since the lubricant can squeeze out onto the o-ring, and the CV joint will be loose. By alternately tightening the nuts, evenly tighten the propeller shaft to the rear axle. Use new self-locking nuts and tighten to 70 NM.
