UCA BUSHING REMOVAL/BALL JOINT BOOT QUESTION

On the Upper BJ an 1/2 " impact wrench and a real 60 gallon air compressor usually will do the trick. The repeated blows from the impact have a way of working the BJs free. I have had to use a BF piece of pipe though in the past, as well as heat. Make sure someone didn't tack weld it to the arm. As far as the BJ boot, I haven't seen them for sale separate, and as there are many types (some with a metal band around the big end, some without) it may be easier just to replace. Next time get yourself a HF tie rod separator and save your boot. This is the large one for pitman arms but there's also a smaller one the right size for tie rods and ball joints.
