+1 on OEM, if you switch to an exhaust boot, you don't need the tool and its kinda a once and done thing. Louder running, but pretty maintenance free.
If you are cutting bellows with your u-joints, check for slop. They may be moving just enough to hit the bellow.
DUH....just ordered from iBOATS:happy:
someone said iboats does not sell OEM bellows kits?
