Tools required
Socket set - notably 8,12,13,14,15,17,19mm, and 1 ¼" socket for hub nut
Torque Wrench
Copper/Nylon Mallet
Large Philips driver
Small punch
Access to workshop Press

Jack up rear of car, leaving handbrake ON. Chock the front & rear wheels on the side opposite the one you're working on. Lower onto axle stand or sizeable block of wood.

Remove wheel.

Using Torque wrench and 1 ¼" socket slacken centre hub nut. The nut will have been punched into the keyway on the driveshaft, so using the punch, try to open it back out before undoing centre nut. It will be VERY tight!
Note: if it's not tight, this may be the cause of your noises - tighten it up really tight, refit the wheel, and see if it's cured.

[NOTICE Uee stable axle stands instead of that dangerous bricks !!] :)

Once the hub nut has been removed, release the handbrake, and remove the calliper, brake pads and then the calliper mounting bracket.

Remove brake disc. This might be quite tight if it's not been off for a while. Hit from behind with a mallet, but try to bring it off squarely.

Once the disc is removed, undo the bottom anti-roll bar bolt and slacken the top one to allow the link to rotate out of the way.

Remove the ABS sensor (8mm socket), and tie it out of the way.

Raise the hub assembly slightly using the jack, in order to take the strain off the lower attachment points. Remove the nut on the track-rod end, and hit the end of the stud with a mallet to knock the tapered shaft out from the housing. (Using a hammer may damage the threads)

Remove the trailing-arm bolt. This is tight all the way off as it's Loctited in.

Oh, Oh, again the bricks ;)
Lower the jack, and undo the top nut. There's a tab washer which will need flattening down before you can undo it. Once the nut has been removed, hit the top of the stud with the mallet, the shaft is tapered again, and the whole housing should then drop. Slide the housing off the end of the splined drive shaft.
Hub Assembly removed.
Hub assembly.
[NOTICE This is an old clout and not K's current bathromm carpet] ;)
You will then need to use a large press, to press the hub out of the bearing from behind, and then press the bearing out of the housing. Be sure to remove the two bearing retaining clips from the housing before trying to press the bearing out!

Press the new bearing into the housing, fit the retaining clips, and then press the hub into the bearing.

As always, refitting is a reverse of removal!
Seriously, if you've got this far, putting it back together is a doddle. Just remember to put loctite on the trailing arm bolt, fold the tab back up on the top nut washer, do the centre nut up VERY tight, and punch the rim of the nut into the keyway of the drive shaft. The piston in the brake calliper will retract by turning it clockwise a few turns.

Good luck.


Zuerst oben und unten anpacken und rütteln
- klapperts ? ... dann ist das unter Kugelgelenk defekt.
Austauschen lassen, Spur einstellen

Wenn es da nicht klappert, dann ebenso heftig rechts und links das Rad packen und 'waagerecht' rütteln.
(Ist schwierieger, weil das Rad jetzt ja auch lenkt)
- klapperts ? .. dann ist das Spurstangenendstück defekt.
Austauschen lassen, Spur einstellen

Wenn's immer klappert, dann ggf. Radlager, oder alles vorgenannte defekt.
