Removing and installing wheel hub with wheel bearing on installed wheel bearing housing (as of CW 12 2008)   Note The special tools, test and measuring equipment as well as aids required for removing and installing the wheel bearing housing of chassis with the FS-III as well as C54 brake are identical. Special tools and workshop equipment required t  Assembly device -MP6-414 (3253)- t  Extractor -MP6-425 (3283)- t  Side door removal tool -MP8-605/1 - or e.g. supplementary tool kit -V.A.G 1459 B/2 - t  Assembly device -T10064- t  Ball joint extractor -3287A- t  Molykote grease -G 052 723 A2- t  Polycarbamide grease -G 052 142 A2- Removing the wheel hub with wheel bearing: –  Unscrew twelve-point nut for securing the drive shaft → Chapter –  Remove wheel.

–  Unscrew nut -1-. –  Pull out coupling rod -3- from the anti-roll bar -2-. –  Remove ABS speed sensor (vehicles with ABS) → Chapter. –  Disconnect the plug connection for the brake pad wear indicator (where the vehicle is fitted with this).

Vehicles fitted with FS-III floating caliper brake –  Removing the caps from the brake caliper guide bolts. –  Unscrew and remove the two guide bolts -arrows- from the brake caliper. –  Remove the brake caliper and secure with wire in such a way that the weight of the brake caliper does not burden or damage the brake line.

Vehicles fitted with C54-II floating caliper brake –  Unscrew bolts -1- from the brake caliper and remove. –  Remove brake carrier with brake caliper and secure with wire in such a way that the weight of the brake caliper does not pull on or damage the brake hose. Continued for all vehicles

–  Screw out nut for track-rod ends -1- sufficiently so that the ball joint extractor is supported on the nut.   Note t  To protect the thread, screw the nut a couple of thread turns onto the track-rod end. t  Risk of accident while the stud of the track rod end is being pressed out: the ball joint extractor can fall off when loosening the steering joint. –  Use puller to remove track rod/track rod end -2- from the steering arm. –  Screw off the nut from the track rod end. –  Pull the track rod end out of the steering arm. –  Tie up track rod. –  Remove the outer joint of the drive shaft from the wheel-bearing housing → Chapter and tie up drive shaft to body. –  Screw steering joint to the track control arm. To do so use the removed nuts. –  Unscrew the securing screw of the brake disc and remove brake disc. –  Remove the cover plate of the brake disc.   Note t  The illustration shows the process of pulling out the wheel hub and wheel bearing at a wheel bearing housing for a chassis fitted with an FS-III brake. t  The procedure for pulling out the wheel hub and wheel bearing of the chassis fitted with C54 brake is similar to that for a chassis fitted with an FS-III brake even when the wheel bearing housing has a different appearance. t  Mount the assembly device -MP6-414 (3253)- at right angles to the centre axle of the wheel hub with wheel bearing. Do not tilt the wheel hub with wheel bearing when removing and installing. t  Two different variants are described below for pulling out the wheel bearing with wheel hub.

–  Insert the side door removal tool-3- between the wheel-bearing housing and the wheel hub as support for the assembly device-2-. –  Pull the wheel hub with wheel bearing out of the wheel-bearing housing. 1 -  -MP6-414/2- with -MP6-414/5- 2 -  -MP6-414/1- 3 -  -MP8-605/1- 4 -  -MP6-414/10- 5 -  -MP6-414/6-   Note t  Instead of the side door removal tool -MP8-605/1- use 2 bases (with a thickness of approx. 25 mm, a height of approx. 40 mm and a length of approx. 220 mm) between the wheel-bearing housing and the wheel hub as support for the assembly device -MP6-414 (3253)-. The arrangement is similar to the separating device - E-37- (fig. S40-0182). t  If the separating device -E-37- from the supplementary tool kit - V.A.G 1459 B/2- is available then this can also be used as a support. Please note the correct installed position while doing this. The straight surfaces of the cutting edges must point towards the wheel hub.

–  Insert separating device -3- between the wheel-bearing housing and the wheel hub and take up the weight. –  Pull the wheel hub with wheel bearing out of the wheel-bearing housing. 1 -  -MP6-414/2- with -MP6-414- 2 -  -MP6-414/1- 3 -  Separating device -E-37- from V.A.G 1459 B/2 4 -  -MP6-414/10- 5 -  -MP6-414/6- Installing the wheel hub with wheel bearing:   Note

t  Figure S40-0180 shows the wheel bearing housing for the chassis with the FS-III brake. The procedure for cleaning and greasing the holes on wheel bearing housings for the chassis with C54 brakes is similar to that on the chassis with the FS-III brakes. t  Clean the bore holes on the wheel bearing housing. t  Coat the bore with molykote grease -G 052 723 A2- over the entire surface.

t  Screw the grippers-3- to the wheel hub with wheel bearing -1- using wheel bolts -2-. t  The wheel bolts -2- must not protrude from the rear of the grippers -3-. t  Figure S40-0183 shows the procedure for pulling in the wheel hub and wheel bearing on a wheel bearing housing for a chassis fitted with an FS-III brake. t  The selection and arrangement of special tools for pulling in the wheel hub with wheel bearing into the wheel bearing housing of a chassis fitted with an C54 brake is similar to that for a chassis fitted with an FS-III brake. t  Do not tilt the wheel hub with wheel bearing while inserting.

–  Pull the wheel hub with wheel bearing into the wheel-bearing housing. 1 -  -MP 6-414/5- 2 -  -T10064/1- 3 -  -T10064/6A- 4 -  -MP 6-414/10- 5 -  -T10064/4- –  Pull in the wheel hub with wheel bearing until the circlip is heard to click into position.

–  Screw out the grippers-1- from the wheel hub with wheel bearing -2-. 3 -  Wheel bolts –  Install the cover plate of the brake disc. –  Install brake disc and secure with screw. –  Install track rod with track rod end into the steering arm and tighten.

–  Unscrew nuts -arrows- and remove bottom track control arm from the steering joint. –  Insert the outer joint of the drive shaft into the wheel-bearing housing → Chapter. –  Install brake caliper in reverse order to removal depending on brake caliper type and tighten. –  Connect the plug connection for the brake pad wear indicator (where the vehicle is fitted with this). –  Install ABS speed sensor (vehicles with ABS) → Chapter.

–  Insert coupling rod -3- into anti-roll bar -2- and tighten nut -1-. –  Tighten new twelve-point nut for securing the drive shaft → Chapter –  Tighten wheel.   Note It is necessary to perform a vehicle alignment in the event of → Chapter. –  Perform a test drive. –  Check the steering wheel position during the test drive.   Caution If after the test drive and with the front wheels pointing straight ahead the steering wheel is off straight, perform a chassis alignment → Chapter.
