Hi

I dissemble the rear diff to clean an painted for protection, it was getting surface rust.

First Question: Will it hurt anything if I pack with grease the axle Berings?

Second Q: What is the torque specs for the bolts that hold the axle in place?

I have a 1989 GTA

 

Assuming since it's an 89 GTA that you have the 9-bolt? if so, see post #3 of this thread for torque specs.

I don't see why greasing the bearings would caust any problems, as long as you don't unseat something that needs to stay in a certain place.

 

Those bearings run in gear oil, not grease. Just put some gear oil on them and put it back together. No grease.

 

Thanks...

 

What is the difference between these two?

Bearing Cap Bolts-Ft Lbs. 45
Axle Retainer Bolts-Ft Lbs. 36

Are't they the same bolts?

 

Nope, not the same bolts. Bearing cap bolts are inside the housing holding the differential in.

 

Thanks so then the bolts I'm talking about are the Axle Retainer Bolts-Ft Lbs. 36

 

Yes.

 

Will it hurt anithing if insted of 1.7Qt I put 2QT?.

Since it is off the car I have the ability to overfill.

 

Do not overfill. The oil will just find its way out anyway & make a mess.

 

It may leak. That rubber plug in the cover tends to leak anyway. I usually clean the cover and the plug well and then put a little RTV around the hole before I put the plug in.
