pulls to the left

I have an 09 dbl cab and I had the leaf spring tsb done and ever since that my truck pulls slightly to the left. Dealership tells me its due to the crown in the road. But if I am in the far right lane the truck still goes left..wtf.
I will take it back this week and see thy say again. I was told before it was in specs. but like someone pointed out just because its in spec dosent mean it is right.

 

Definitely need 4 wheel alignment check and have them give you a printout of the specs. NTB usually does a good job with mine.

 

I will have them do that and put up here..

Thanks
