Check my other auctions for other high quality Ford Racing Parts FYI - As many of you may know or maybe experiencing, Ford has had some recent troubles with rear end noise, chatter and excessive axle bearing wear in some of the newer model years of their light trucks and cars including the Explorer, Crown Vic, Expedition, F150 and others. They are now suggesting the use of the 75-140W synthetic gear oil along with this friction modifier to take care of some of the excess noise and prevent premature bearing and ring & pinion wear. This stuff is used standard on many of their heavy duty vehicles including the Expedition, Excursion, F150 and others. Do a search on the internet to find out more. Adding new limited slip additive may help in some cases. Please refer to your owners manual for proper replacement intervals of your gear oil and also for the proper recommended type.
