[V8] How to R&R rear diff seal...& what type of fluid..75-90W????

[Stafford, Kenneth A.]

Ron,

After I took out the center bolt on the axle flanges, they just pulled right out without any special tools.  I cut new gaskets out of thin gasket material and used Formagasket to seal them.  I've had no problems since (4 months ago).  I also used some sort of Autozone diff fluid that matched the manual's specification.  My original rear dif went south after about 190,000 due to a very slow leak that eventually let the unit go pretty much dry.

Good luck!

Ken
