12 Bolt Axle Fluid - Recommendations
« on: September 09, 2013, 02:24:12 PM »
Hey folks - I'm in the process of doing an R&R of the 12 bolt rear axle seals in my '69 pace car, and as such need to refill with lube.  I am thinking that a synthetic would be best but looking for experienced opinions regarding a particular brand, etc.   Any recommendations on best lube/fluid to use for this application?  I want to do it once and do it right.  Thanks in advance for your input.

Any brand-name 75W90 or 80W90 GL-5 hypoid lube, with one or two 4-oz. bottles of GM Limited-Slip additive; you don't need any "miracle" lubricants.

Sage advice from the master himself.  I'll take that information and run with it. Thanks again!

A good name brand gear oil will do the job. I've heard the synthetic may be a little too slick just like for trannys also.
