Twisted my truck. .

[flynaked]

Ok I'm still on a stock rearend in my 2000rcsb, suspension is bone stock save for 2in lowering shackles, I decided to order some 28x11.5 m/t for the stock wheels. I decide to go out for some testing on the street, only my second time out with them. They feel great and have cured the spinning for now, however I decided to slow it down and try them from a dig, I come off idle to about 2/3 throttle as soon as I'm moving I hit WOT, there wasnt any perceivable spin just launched hard, felt great. Problem starts when I get home and notice the truck is twisted to the left, the right wheel well is sitting just over 2in higher than the right side, I notice fresh scrapes from the overload springs contacting the leaf pack. Then I get down and look at them and both of the overloads are tweaked about 2 degrees pointing to the right ( looking from behind). Could this be an effect from the stock shock locations, one fore and one aft?? My plan is to loosen the U bolts tomorrow and try to get it sitting right again, only thing I can think is there is some nasty axle wrap going on that tweaked something in the rear suspension, any ideas? This happen to anyone else?

That's possible. You may have sheared the locating pins off. I'd take it apart and inspect it

Did you re- torque the u-bolts after the first 50-100 miles after installing the 2-inch lowering schakle? Edit did you even remove the leaf springs to install the shackles to make the install easier? If so did you re tighten them after driving the stated miles?
