Rear Differential question


Recommended Posts

All,

 

I've got my 89 up on floor jacks working on the brakes. While I've got it there, I'd like to change the rear differential fluid.

 

Is there anything I need to be aware of before I start?

 

As far as I know, it's never been changed before.

 

Thanks,

Robert

i usually leave 1 or 2 bolts on the top of the diff cover loose but still in so when you take the cover off the oil doesn't go everywhere.

 

I agree, also you will need some RTV for a gasket unless you have the paper Jobie. (Even then I prefer the RTV.)

 

Clean both surfaces spic and span clean. Lay down a bead all the way around. Let it set up for a short time. Install but don't torque down right away. Allow the RTV to set up a bit more then tighten down in a criss cross pattern. Fill with hypoid, but don't overfill. If filled properly, you should just be able to touch the fluid if you stick your little finger in the fill hole. Don't for get the add the slip agent if you have a L:S diff.

 

Good luck,

CW
