Wheel bearings? Hard or not?

Hey guys its been a while. I dont know if any of you remeber the yellow car macfreak007 bought for 500 dollars, but I own that car now.

It needs rear wheel bearings on both sides. Aside from the gigantic torque of the stub bolt, is there anything too hard to this job? I read a writeup on Clarks-Garage and it didnt look too bad. Anyone got any experience?

I have done a few and Clark's write up is a good one. The first one I did was because the stub axle broke while on the track so that dang nut wasn't a problem, it was laying in turn 9 at road america or somewhere. That time I was not able to freeze the wheel bearing and had the wheel bearing installation tool available.

The other times I did not have the tool available and found that freezing the bearing and heating the control arm did help in getting the old one out and the new one in. I heated for both removal and installation.

If the bearings haven't gone so bad that they have eatenen into spindle or housing, a peices of pipe & a brass punch is good to have.

I suspected mine were going bad when I heard the clink-clink while rolling out of the garage. Sure enough the clink-clink becomes a major tail shake above 30mph. Replaced the rear bearings and rolls smooth again.

Not a hard job, but having the right tools makes it so much easier.

The bearings are the same as superbugs at half the price.

AFJuvat/britwrench/alex/others can anyone verify the superbug wheel bearing swappability? That would sound like a steal if there aren't any problems with doing that.

Rock,

How's it going?

The bearing replacement is not too bad, just follow the Clarks procedure. Are you going to have Andy help you with it? He has done a few.

Going to the first autox of the season this Sunday? I've never autox'd in snow before, should be interesting.

Take care,

J.

Not really that hard just messy, very messy.

You can borrow the large socket for removing the castle nut from an autoparts store. Many of the discount places have a tool lending program....ie...free.

Follow the instructions very closely.

The 944 inner and outer wheel bearings are the same as certain VW/Audi ones.

It's pretty easy as long as you work at a good pace, and don't get frustrated when things don't come apart easily. Equip yourself with the necessary tools beforehand. Of those the most important will be: PB Catalyst, a torch (Oxy-Benzomatic or Oxy-Acetlyene), and beer.

I found the easiest way to get the new bearings in, is to take an old one and grind the outside quite a bit so it flops in and out easily. That way you can apply pressure (or poundage with a hammer) evenly.

I've done rear wheel bearings on early and late cars, and doing a late car is a major PITA!

Early cars have an inner and an outer bearing and the fit is farily loose. The late cars have one bearing, and it is a very tight press fit. To do a late car you need to heat the area around the bearing and use a STRONG bearing puller. To get the new bearing in you need to heat the trailing arm, and cool the new bearing (I stored mine in the freezer), and install the bearing as quickly as possible, taking extreme care not to get the bearing cocked.

For both early and late cars I highly recommend replacing the bearing seals, and for early cars there are a couple of spacers for each axle that need to be replaced as well.

This would also be a real good time to clean, inspect and re-pack the CV joints.
