I bought this front upper arm bushing for the differential mounted one for my 02 Jeep Grand Cherokee Overland. I had to saw the body of the old one and chisel it out. To put the new one in I had to use clamps and it worked fine. By the way, in case you didn't know, you have to lift the car by the frame so that the differential stays down and you have more space to swap it out. After installation it runs very well. I don't feel any rattling when switching to DRIVE or REVERSE.
