This is for the do it yourselfer with no welder and a rusted for life track bar bolt at the bushing end. I have a 97 tj with probably an original track bar that had lived all its life in the great salty Mn winter and humid summers. This bolt and nut with the "tab" was not going anywhere with Pb blaster .....days of soaking and heat . I had to cut the bolt off and cut the tab off the nut to remove that piece also . So the next problem was grabbing onto that nut in that little box that attached at the axel end and being able to torque to spec . Had to make myself a tool . I searched the form and found no other solution . Here's a pic . Hope it helps somebody sometime
