About a 18 months ago, I had my rear end totally rebuilt. New axles, GM gears and Auburn posi. About 6 months ago, it started grinding during low speed tight turns...which I recognized as a lack of posi additive. So I added a tube and it went away. Well, it started doing it again about a month ago, so I added another tube...and it went away. But it's doing it again.
What's going on here? I raced it at the track for the first time last weekend (12.38 @ 112) in 3 years. So you can see, I don't have too much power for it to handle. My trans does shift very hard, which might be putting extra stress on it...
TIA,
Terry
