I have ran 867 miles so far and noticed that something is more off than thought. The rear tires are wearing on the inside and dont find play in the rear wheels. I am also seeing that the right side is sitting lower than the left, was thinking just because the spring packs where not the same. The left pack is 12 leafs and the right is 10 leafs not including the helper, these packs are a bit stiff. This truck was in a accident under ownership of the past owner, so making me wounder if am dealing with a bent axle along with the mismatched packs. Center of the front axle to the bottom of the fender is 26.5in and would like the rear to be 2in higher than that, one side is about level but the other has a mad lean. What spring and block combination would be ideal for this, would 08+ spring be easy and simple?
