My JGC needs a change out of front and rear differential fluid. My owners' manual calls for 75W-140 with a special friction additive sold by jeep.
Question: Anyone know an on line source for 2 gallons of 75W-140 lube? None of the three auto parts stores I visited today had any in stock. TIA
The friction modifier comes in a 6oz bottle from the dealer only and I use mobile 1 synthetic diff oil. If you do not use the friction modifier your rear will be toast in 6 months.
Just about every GL-5 gear lube appropriate for an axle *already* has the friction modifier additive included. Look on the back label where it will include words to the effect "compatible with limited slip differentials".

I have to agree with you Bill, the label says compatible and does not say anything about containing or meeting the manufacturer's specifications for the limited slip additive.
