On the tire thing, this is the thing that has had me vexed ever since my Jeep was 3 months old. Stock tires drove straight, BFG all terrains no lift pulled to the right, lifted it still pulled to the right, changed tires to 33" copper stt's pulled to the left with no change to anything. Switched to 32" goodyear MTR's still pulled to the left, changed to 35" Mk MTZ's still pulled to the left, changed front axle adjusted and centered everything still pulled to the left, changed to 34" Krawlers with no other change than swapping tires it goes straight with a very slight wander to the right. You go figure that one, must be a Jeep thing, it has me stumped
