I have a 2 inch lift kit with 28in tires, i been having them on there for about 3 months and then one day i was doing some water wheelies and it broke. So i went to honda and bought a new one put it on went mud riding the next day and it was slipping off of the drive shaft that goes into the moter so i took the rear end off again and i saw the seal that goes into the moter was leaking, so i put a new seal and add me a little spacer on the splines on the drive shaft so it woulnt slip again so i put it back togther and went in my crawfish ponds and was doing some more water wheeles well it snaped again and the u joint broke i dont know what to do any more i hired the turner u jonts were good but does anyone know if they last long and if they can bend more than the stock one.

please help

thanks
