I'm kind of curious if anyone has had problems with there rear ends. I pull heavy boats out of the water for a marina (up to 23000 lbs). Ive spun the tires a few times to get up some of the wet ramps. When the rear end temp gets to 150 or i come off a exit ramp after a long ride, I go to take off from the stop, and get a sensation like it's got a chipped side gear or bad bearing. It does'nt matter whether i'm pulling or not. I've eliminated the possibility of u-joints or center support. Thanks Brian

 

What have you got your TST set to?? These rear ends weren't made to handle much more than stock, especially if your pulling an extremely heavy load uphill.
