7.5 open diff problems

what do you mean it spins? on a 7.5 rear end only one tire holds all the power as in one tire peel out while the other just sits along for the ride. So one tire preaty much does all the work

don't get on the gas hard when going around corners on wet pavement. sounds like he is trying to get to spin. I had a 95 v6 a few years back & it would get squirrly on wet pavement. come to think of it though....the inside tire was the one that would spin on mine. I never figured out why it would fishtail on wet pavement when only one wheel was spinning
