I meant jacking it up under the pumpkin, not the track bar itself. When I had new tires put on, they lifted it with a floor jack under the front diff cover and afterward I noticed the axle was off center a little over an inch. Now it may have already been that way, and I just didn't notice. Finally figured out the track bar was bent and centered the axle by installing a new factory bar. I thought they should have jacked it up under the frame rails, but have been told that many shops do lift under the pumpkin, however, since the left bar mount is on the frame and other on the axle, it seems to me the bar could get kinked on the curved part of the bar by the weight on the end of the axle.
