Title: Rear wheel bearing
Post by: manc on 02 December 2010, 22:43:57
I'm fairly sure from the moaning coming from the back of the car (No offspring or partner!) that one of my rear wheel bearings is on it's way out, how much of a pig is it to do? (Had TIS but won't load on my new PC) it's a facelift TD estate, any info apprieciated

Buy a good used one instead of trying to replace the bearing complete PITA by all accounts :y

the most difficult job on the mig.. but if you do it in a service let them bother with it :). i changed mine 1 month ago. it was ~50pounds OPTIMAL was the brand. the service only took 15pounds because i bargained with them before but they weren't so happy after i went to pick up the car. they said it took them 2 hours to do it. all i know is that the "drive shaft" (the part between the wheel and the diff) had to come out.

If it comes out easily, the job is not too bad...

If tis seized in as mine was.....we had to removed the trailing arm and sledgehammer the old bearing out!


Garage job imho  :y

Not a easy diy job.

Requires the help of a fairly large press and quite a bit to strip down and remove first.

Find a local trusted garage and get them to give you a fixed price for the job,that way you know the costs involved before you start.

Genuine GM bearing is about £40 but they can be got much cheaper from fleabay,but unsure of quality.

Best of luck with it.

Hi,
This really is one hell of a job on Mig.
I have changed both sides on mine. NS took 5 days because bearing siezed in, OS took 3 to 4 hours as no probs, and had already done one.

Saloon and Estate have different bearings. I think mine were about £50.00 each from Europarts.

To change with good secondhand will mean exchanging not just the hub, but the hub and trailing arm complete.

You have to have a load of gear to do this job. Pullers, bits of large pipe, bits of iron etc for strongbacks, studding etc, Ramps, Jacks, 32mm socket and means to apply 250 ft lbs force, as well as understanding how it is all assembled. A good mechanical aptitude, and loads of self confidence.

If you look back on General help 15 Nov 2009 @17.04 and 18 Nov 2009 @ 01.12 and 25 Nov 2009 @16.31 and threads around 5 Aug 2009 you will see some of the problems encountered.

If you still wish to go ahead, PM me, and I will send you descsription of how I did mine and drawing of some of the gear you will need.

Roger

it's held in in just the same way as a modern fwd.

it's not that hard a job to do, but you must remove the semi-trailing arm and be prepared for some chopping/grinding.

procedure is :-

undo driveshaft
loosen rear hub nut
remove semi-trailing arm
remove drive flange
press out hub
remove wheel bearing
grind off inner bearing race from hub

assembly as they say is the reverse of removal, but be sure you don't push the new bearing apart.

Swap the arm IMO.

Never done either job though.  :-/
