How to change a seirra rear wheel baring?
Steve Lovelock - 30/3/11 at 07:49 PM

Hello,

I'm thinking of changing my rear wheel bearings whilst I strip the back end down to replace the wishbone bushes and not sure what is involved in doing the barings at the same time. Any ideas if it straight forward or not?

Also, can the barings be bought on-line to save money?

Cheers
Steve

The bearings consist of two pairs each side i.e. four in all the inner and outer race are seperate so all you have to do is bash out the outer race from the bearing carrier on each side, I got mine from ebay

Crack the big nut before removing anything else apart from the wheel, can't remember whether they are handed though, one pure tw@ if you try stripping them off the car.

Are they noisy? You don't have to remove the bearing carrier to sort out the rear bushes if you do one arm at a time. If you do decide to replace the bearings, slacken the hub nut before jacking the car up as already suggested (41mm socket IIRC) jack the car up and put on stands remove hub nut, rear wheel and disc/drum the remove the bearing caliper bolts through the large hole in the driveshaft flange . Remove bearing caliper, take out bearing seals and inner bearings then use a drift through the hub and drift out the outer bearings. Pack the new bearings with fresh grease, get as much as you can into the bearings , you can't over pack. Separate the inner bearing from the outer race , place the outer bearing race into the bearing carrier then use a brass drift or if you can get hold of one, a bearing drift to drive the race into the hub Make sure the race is fitted the correct way into the carrier. If there is a spacer between the bearings put it in now .Repeat for the second race. Fit the seals and reassemble the carrier . Final tightening of the hub nut is best done with the wheels on the floor.

As above - I put a few pics on my website here http://www.alfadax.com/content/before/sierra/sierra02.htm after I had to ask all the same questions!
You need a bearing splitter to get the inside one out though.

Not cheap either - I think it was the thick end of £50 for both rear bearing sets. Unless they're making a noise, I wouldn't bother tbh.

Dead easy, take them to bits and the tapered races knock straight out.

Got mine off the shelf at Caprispares last year when upgraded to an lsd. They do most of the Ford shows ad some classics as well.
