Can someone please provide a procedure for changing the rear axle gear oil?
What areother TB owners using for rear axle oil? i was thinking of using MOBIL 1 75W90. Any comments?
Thanks.

According to my manual... the Mobil 1 will be fine. Differential fluid should be changed out at 60,000 miles or 48 months whichever comes first. drive the vehicle around for a bit to warm up the fluid. Then drain it out through the bottom drain plug. Clean and replace the drain plug. Then using a hand pump, syringe or a squeeze bottle, refill the differential to 1/2" below the upper fill plug hole approx. 2.6 pints. I hope this helps you out, -Don
