AU Diff Whine. What is the additive to quiet them down???

hey guys, i have a 1998 AU Fairmont and I have read on here and on Fordmods.com of an additive that you can get from ford that you put in your diff to cut out diff whine. Appearently its pretty common in AU series 1's. I droped my car off at ford this morning for the recall job, and they recon that it is not common at all and that there is no additive that they have or can put int to quiet them down.

Does anyone know what it is that they put in there to shut em up????

Cheers Guys

I asked Jim Mock about that and he said there's nothing that can be done for that first gear whine, if that's what you're talking about.

No additive will fix the whine. The diff needs resetting. If left too long, it will need a new crown wheel and pinion as well. Very common for AU to drop pinion bearings at as low as 40k.

get Mal Wood automotive to throw in some shorter diff gears and an LSD center when you get the diff done man as others have said, there is no magic oil to fix the whine.
