Leaky rear dif

My 95 YJ is starting to leak at the rear dif. After changing the gasket do I need to add Positraction Fluid?
How about suggestions for a leaky power steering unit.

Tim,

On there rear, where is the leak coming from? Did you get 99.9 of the old gasket off when you changed the fluid? Also check the cover for and inperfections that may be preventing it from forming a good seal with the gasket sealer stuff. As for the steering unit, get everything as dry as you can and see if you can tell where the leak is coming from.. perhaps its a bad fitting or hose, good excuse to change the fluid there too.

You don't need to add "Positraction Fluid" unless you have a locker, just regular gear oil will do, mobile 1 or whatever.
If still seams like it is leaking after your done check the pinion oil seal, oil will run from it down to the bottom of the diff making it look like it is the diff that's leaking.

Actually I think Its' an original '95 factory gasket. Someone told me the "Goopy" squeeze & stick stuff is the best. I'm thinking an OEM Mopar Gasket........

OIC.. well, the mopar stuff is fine.. or a high temp RTV kind, I think the blue or orange one should work fine, sold at most auto parts stores.

It helps to take either a sanding disk on the air tools or a finish wheel on the grinder to the diff and the cover to ensure that you have a good bonding surface for your sealant. There is a sealant called "The Right Stuff" They sell it at Napa or Home Depot and such. It is more expensive, but it will seal even an oily surface.

Incorrect, LOCKERS use regular gear oil, "Positraction Fluid" only needs to be used in diffs with limited slip units in them. "Positraction Fluid" is considered friction modifyer, if not used the clutches will chatter when cornering, usually felt more than heard.
