TJ diff fluid
I am wanting to change the fluid in the front and rear diffs and I am not sure of the capacity or which axle I have. The front is stamped with DANA 40869-136-0 and the rear is DANA 43225-115-0. I am thinking the front is a Dana 35 and the rear is a Dana 44 but I might be wrong. It is a 2001 Sahara. Thanks

The front is always a Dana 30 for Saharas & your rear axle could be either a Dana 35c or a Dana 44. Do you know if your TJ has a Tracloc rear limited slip differential? Check out the rear axle pics in so you can tell what your rear axle type is.

welcome to the forum, first of all your front is a dana 30, they all are 30's untill the rubicon. your rear is most likely a dana 35 unless you are lucky and it has the very less comon d44 out back. either way get yourself 5 qts of 80w90 gear oil, a gasket scraper, and a tube of rtv and you're ready to cause some damage.

here's a link that will help you determine which rear axle you have: Axle Identification Chart

if its limited slip in the rear most synthetic gear lubes will have the additives already.
