Had the local Jeep dealership perform some maintenance on the rear axle of my Jeep GC. They refilled it with gear lube but not friction modifier. It is a Vari-Lok limited slip differential.
They claim the tech who did the work is top-notch on Jeeps and he says friction modifier is not needed on the Vari-Lok. My Factory Service Manual says otherwise. I had them put the FM in before it left the shop.
Anyone heard of a factory change in protocol on this??
