rear end alignment

My buddy told me that my truck was driving sideways down the road.. If i put my front driver tire on the line while driving the back was 3" off the line. I took the truck to the dealer, and they verified something was off. I have tsb leafs already installed.. the dealer could not get it aligned right. The dealer called toyota, and toyota said to order a new set of springs thinking one of the holes was drilled off center..anyone else have this issue?

 

so heres the deal..the back was way out of alignment. the dealer ordered new tsb springs. on inspection of my old ones there clearly saw the holes where not centered for the alignment pins on the spring perch.. new springs solvedf my issue

 

Rep to you for getting back to us with the resolution. So many folks will ask a question but then don't come back to report how it turned out.

 

Yeah, my guess would have been springs, I had the same thing happen on my old 69 GMC, dog tracked down the road until I had a bad spring replaced and the other re-arched. Fixed it right up.

 

You had rear steer stuck turning left
