The additive is Motorcraft Friction Modifier, available at a ford dealer, and some parts houses.
It’s a limited slip air locker
So it only locks up when you apply the air and during normal driving it acts like an open diff?
It’s a limited slip
ARB doesent recommend using the additive for the reason it eats up gaskets is what was stated I’ll have to find the link and post it
That's exactly what I put in mine.....and got it off of Ebay for pretty close to the same price as the dealer had it for but I didn't have to drive 25 miles to get it. The only problem is that I paid for 2 bottles and only got one but the dealership that was selling it sent me another which got here within a couple of days. Wasn't quite ready to put it in anyways....in fact it sat here for a good month before dropping out the oil that was in the rear end lol
Yeah, Im thinkin thats why my Diff cover leaks now. Going to try this LubeLocker unit, gasket. Hoping for the best!
Well, my Dana 70 holds 3 quarts and I'm thinking it would be fine with a bottle and a half but I dumped both into it. For the 2 quart 8 3/4, go with one and see how it does.....
My diff cover was leaking more with the synthetic and dripping but using the old gasket on a cover that should be using RTV with the regular oil, it's wet but not dripping.....yet lol
BTW, a diff cover that's smooth is supposed to be used with RTV.....and the embossed cover is designed for a gasket. If you have a smooth cover, use a minimal amount of RTV. Most people use WAY too much.
Yup, that's the stuff everybody likes, even Dr Diff.
