Had to replace the hinges on my 99 tj, I was able to get 4 of the 8 torx bolts with a hand held impact driver and a 1/2 inch air wrench. Broke 3 T40 sockets on the others. Found a simple solution that others may have shared but just in case. Drill the T40 head out with a bit same size as the threaded part of the bolt, the head will come off and the hinge can be removed. Then weld a regular nut to the bolt that's left and while hot turn out with a wrench. Hope this helps
