Leaf Spring Terror
If you are trying to remove it, a propane torch works great. Just aim the flame through the hole in the sleeve and the rubber will promptly melt allowing the sleeve will slide out pretty easy. Do this outdoors or your wife will complain about the smell of burning rubber LONG after the smoke goes away (like 10 years). And of course, the bushing will be trash after you do this, but the sleeve will be fine.
