diff service

[jimmydaleo]

I want to service the diff (only one).. It has the e locker can I use royal purple 75-90 or is there something special I have to use because of the locker?

Dunked a diff?
Time for some breather tube extensions.
No need for any special friction modifier in a locking diff. Just fill it with what the manual recommends.

Nah. just want to keep service up. I use my truck for all my major off roading. I just don't trust 2wd even with a locker for anything major.
