Hey Guys ,
Just looking for a rear diff fluid I can get from a local auto store.
Any recommendations with weight #'s ?

I'm guessing just fill it until it levels with the top fill hole, right?
And yes I searched but did not find the answers I was looking for.

thanks!

75-90 or 80-90 will work fine should take like 2qts get 3 just be safe

 

75w90 for front diff / txfer case and 80w90 for rear diff is recommended
x2 on buying 3 qts
Don't know why there is a difference in weights between them

 

Thanks guys......... any recommendations on brands sold in checker/auto or pepboys?

any brand GL-4 will be fine

 

 

AmsOil or Royal Purple if you are going to get Mobil 1. I put AMSOIL in mine and I love it! It is about $10 / qt. I used about 6 qt for all two diffs and txfer case.

 

Most of the auto stores carry GL-5 rated fluid
Is that a higher rating than GL-4 and o.k . to use?

The only Gl-4 rated gear lube was COASTAL brand at autozone.
Looking like the no frills brand.........I was cautious
