Has anybody installed these on there Jeep? I bought one because mine had a groove worn on my old one. The doesn't seem to go on as easy as the stock one did though. Has anybody had the same problem? I also had this kind of problem when I installed one on my old Camaro. Only have the problem with the Dorman balancers. I even tried to heat it up a to about 175 in an oil bath. Just the stub though I didn't soak the rubber in oil.
