Diff Fluid Change.....

[Marchiafava99]

Ok, maybe I'm blind but, where do I fill my diff from? Bought a new gasket and fluid to change it but couldn't find where to fill from!?! Am I blind? Thanks!

I'm sure your not blind if you were able to drain the fluid into a containment device...As for filling, look to the fron of the diff, on the side, above center, you will see a plug that a 3/8 extension end will fit into. unscrew that plug and fill up to just below the hole...

Thanks! Musta missed it somehow?!

No sweat,your welcome. It's probably filled in with dirt or something, kinda blends in with rear after a few years.

is this diff limited slip?

[jethro]

it should be on the front side of the diff where the drive shaft comes in on the about 3'oclock position on the drivers side of the case

You actually need to know that before you refill the fluid. Limited slip diff.'s require a special additive. Lift the rear axle with trans in neutral. Spin one wheel and watch the other side... if it spins opposite of what you're turning its an open diff., if it spins same direction as what you're turning its limited slip.

I think it's limited.....limited to just the right rear spinning!!!!! Should I use RTV or something on the gasket? felpro gasket BTW.

if memory serves me, if itsnot a limited slip the wheels spin opposite directions. if its a posi then the same. If the other side does not spin(i May be wrong, hope i am) doesn.t that mean its a limited slip but the clutches areworn so the other side is not spinning? Someone will chime in.
