4 Wheel Drive/SUVs: 1998 TJ Wheel lift problem, accelerator pedal, wrangler tj

Question
I have a 1998 Wrangler TJ. It has a 4" lift , 33/12.50-15 tires, 2.5L engine with 5spd. trans. I bought the jeep like it is. When I am at a stop light and go to make a left hand turn the left front tire comes up off the ground.All I have to do is quickly tap the accelerator pedal to the floor. This is a four cylinder engine, so I don't think excess power is an issue. This really concerns me , I don't think this is normal. I have asked around at some four wheel drive shops near home and nobody can tell me the problem. They just say "wow". I was just wondering if you've heard of this or might have a solution. Thank you, David

Answer
This may be due to gearing and maybe someone has welded the differentials. Welding the diffs make all 4 wheeld pull at the same time and will cause binding on the road. I would pull the axle covers on the diffs and see if they have been welded causing the issue
