assuming you have 4 wheel drive, are you making a tight quick turn? if so you may be locking up the front axle causing the problem.
I would also have your transmission looked at. Its possible when you make the turn (tight or not) that the trans is slipping due to the shift in weight of the jeep. This could lead to the trans failing. And its costly to rebuild one.
