I was having problems with my differential leaking. I tried to fix it once by myself using RTV, then also had a shop try to fix it...also using RTV. Both times it kept leaking.

So I went to Lubelocker.com and got a gasket (8.8 diff). I cleaned the cover and the differential and used only the gasket, no RTV. The differential hasn't leaked at all, and its been a few weeks since the installation (I installed it).

I'm extremely happy with this product and would definitely recommend it to anyone that's having leaky diff issues.
