ok im new to this board so bear with me. I have a friend who has a idenical car as I do. Its a 1990 Camaro RS with a 305 T.B.I. and a automatic. He needs all new wheel bearings on all four wheels. I have never had to replace the ones in the rear. How hard is it? Do i need to take the diff. apart to do the rears? The fronts are not hard to do at all. I just need help on the rear. Any help would be appreciated. Thanks

 

To replace the rear bearings you will have to remove the axles. Take the diff. cover off. You should see the ends of the axles held by a c-clip. Push the axles toward the cinter of the diff. and you should be able to remove the clips. be carefull not to damage the oil seals! After the axles are removed, you should be able to remove the bearings. Don't forget to replace the axle seals too. Good Luck!

 

you basicly have to take the c-clips out of the carrier to slide out the axle shafts to gain take the rear wheel berrings out.

 

It's not hard to replace the rear axle bearings, it's just messy.

Once the diff cover is removed, rotate a wheel to rotate the carrier until you can gain access to the spider gear shaft retaining bolt (for lack of a better term).

Remove the retaining bolt and then carefully remove the shaft. Note which side the spider gears are located in the carrier, and also note which thrust bearing goes to which spider gear. You'll want to put these back in the same locations.

Push the axles inwards and remove the c-clips. Sometimes they will fall out on their own.

Pull the axles, seals and the bearings.

Inspect the axle where the bearing rides against. If the bearing is bad, most likely the axle is bad too.

Reverse to reassemble. Use new seals and a new cover gasket. Don't forget to refill and add GM limited-slip additive as required.

 

To remove the bearings and seals, use a piece of about 3/4" water pipe about 6' long through the axle tubes

 

If you see any wear on the axle, just use some 'repair' axle bearings. The bearing will then ride on a new part of the axle. The repair bearing has a built in seal as well. Be careful when you slide in the axle so you don't tear the new seal--you won't be happy if it leaks.
