I am on my second xj, and both of them had weak struts, to where you lift the hatch, grab the groceries or whatever, and immediately get whacked in the head by the hatch on its way down. That sucked after a few times, so I decided it had to be fixed. Being cheap, I found that there is room to move the strut bracket on the hatch down about half to 5/8 inch, drill new holes in hatch and reinstall bracket. This changes the geometry, giving the strut a little more leverage on the hatch. They work like new now, at the cost of a couple inches of lift. Since I am only 5'10", no problem.
