remove the tension on torsion bars

You can easily remove the T-bar by prying the LCA away from the K-frame (after you loosening the pivot bolt's nut and removing the front strut rod nuts), then wack the LCA forward and the T-bar should pop up. Of course, remove the rear wire clip retainer first. The special "T-bar grabber" tool shown in the FSM is unnecessary, and for sure don't grab it with pliers. Note there is a L & R T-bar. Both the PN and an "L" and "R" distinguish them. You must keep on the correct side. Flipping each one end-end doesn't matter. I like to put the "L" & "R" at the end so someone could later verify. Many here like to upgrade to a stiffer T-bar and 1"D seems most popular and thus inexpensive. I used the polyurethane rear grease boot since lasts forever. BTW, that grease & boot is to stop corrosion, not to allow movement.
