My 2012 Laramie Longhorn pulls slightly to the right. I took the truck to a shop that does truck alignments and they tried to align the front end, after I put 6 new tires on it. They couldn't do an alignment, and said that it would require adjustable ball joint to get it right. This truck is very pampered, and has never been crashed, bumped, or hit anything. The estimate to install adjustable ball joints and align the front end was about $950.00, which seems super high. Are these ball joints covered by the manufacturer's warranty at 33k miles? I have the statement from the front end shop that they need to be replaced.
