Front & Real Differential Fluids

[etlsport]

hey jack double check the manual, i think that it recommends 70w140 for the rear diff... if you use regular gear oil (ie not mobil 1 or royal purple) you probably need to add LSD additive to it too.. for the transfer case you need a 3/8" socket wrench with a small extension bar to remove the plugs

Changed the diff fluids on the weekend. VX is a much smoother ride now.

Went with AMSOIL 75W90 in the front and a mix of 75W90 and 80W140 in the rear (does that make 77.5W105) to give a wider temperature coverage. Also added AMSOIL's Slip Lock in the back.

Fluild out was pretty black and smelly. Had to poke the front with a piece of wire to get it flowing.

installed new shocks today, noticed i have gear oil coming out of the seal between the rear diff and the drive shaft, so i went to top off the differential, make sure im not low on fluid.. taking off the filler plug released a lot of pressure, i really cant figure out why, i took the breather hose off and its clear, hooking up compressed air to it, there is some pressure build up, theres a white cap at the top of the breather, it seems to be blocking the airflow some, but not enough to build up the kind of pressure ive got there, not sure how i would test if its clogged at the differential, kind of thinking it is, i stuck a coat hanger in there and hit something pretty solid feeling.. anyone know whats supposed to be in there?

There's a pinion seal that due age gets busted.I had that seal replaced few months ago when i had an small leak right there eric

The pinion seal cost 'bout $ 10.00/15.00
