2000 f150 xlt 4x4, I'm in the process of changing the front upper arms, lower ball joints (moog), caster/camber bolt kit, and bilstein shocks. Noticed the rear tire sticks out one side about 1/2 of an inch.

Looked under there and saw one u-bolt on a slight angle and the old rust marks from where the u-bolt use to be on both sides. ( I remmembered that I spun out and hit a snow bank sideways awhile back pretty good)

Anyways looking for tips to fix this when I'm done with the front end before I go for a four wheel laser alignment THX

 

The spring stack has a center bolt that has sheared off.
It locates in the center holes of the top and bottom plates the U bolts are clamping to.
I see a lot of tractor trailers with trailer axles in the same condition.
No body ever checks them by the llooks of it.
Most often, one side is either forward or to the rear.
This shows as the trailer following at an angle to the tractor.
You know how ofter they run over curbs and such. The signs of it are all,over.
Good luck.

 

Bluegrass, i agree, it is unbelievable how many trucks are not aligned in the back. I look at everything going down the road and sometimes i think its 50%.
