I have a 2004 Wrangler sport. With the straight 6 and the dana 44 in the rear sitting on a 4" skyjacker with 33's. I was off road the other week and was going threw a small mud hole (mostly water). Was in 4wd high and in first gear. Came out of the hole then turned around to go back threw it and all five of my studs on the passenger rear tire sheard off. All of them came clean off. Any ideas why this may have happened?
