I got a lifted 95 xj. When I accelerate in 4 hi the front end will jerk left or right. Its not biased and will jerk either way especially if tap the gas hard. Also it seems to veer off when I let off the gas at higher speeds and when hit the gas again it veers back. My 96 xj does not do this; I stomp the gas hard in 4 hi and it tracks true and straight no issues
