my '03 doesn't do that. hell, my '87 xj doesn't even do that! like mentioned above...it isn't even worth messing with it yourself. the price you paid for your jeep was adjusted to comp for that big warranty - get your money's worth!
Mine - '03 TJ RE4.5 coils, long arms, 4.88 gears, arb/detroit, 35" BFG KM2's, 9.5ti, skids, etc.
Hers - '01 TJ RE4.5 coils, 35" BFG's, Hs9500, HP30/8.8, 4.56 gears, skids, etc.
