Home made urethane bushings - urgent
I've used polyurethane insulation (the yellow stuff in a spray can from hardware store) on my front motor mount to fix it. It's lasted for the last 20,000 miles with no problems. 1991 Honda Civic LX Sedan, 5spd.

I'd like to put the Mugen rubber bushings in as a replacement but I don't have a press. I still need rubber because I transport my baby in my car.
There's a million search results and I'm sifting through them.
Also... I have a few questions:
- do you clean out the rubber bushing from the metal sleeve because the urethane bushings don't have the sleeve?
- if I go with the mugen bushing, it should have the sleeve right? and if so, that means I shouldn't have to clean out the old rubber bushing... I need to get the whole busing and sleeve out.
- can i use a little bench press vise to do this?

I usually use a bench vise to hold the bushing while I hit it with the torch. Can't really hold that one in your hand... You need the sleeve, and need to press it into the new bushing, or get a set of bushings that come with the sleeves. If you just put the bolt through it, the diameter will be wrong and the bolt will quickly destroy the bushing.

If you mean the outer sleeve (i.e. metal sleeve that goes around the circumphrance of the whole bushing), then you don't need to do anything with it other than clean it off so you don't have rubber flecks crammed between the metal and the polyurethane. Its a tight squeeze to get the bushing on, so you want to clear off all the rubber.
As for installation, its acutally pretty darn easy if you get a BIG bolt (like 8 inches), matching nut, and two big washers (one has to be larger diameter than the bushing, the other one can be a little smaller), and press the bushing in by placing one washer over the empty hole in the control arm, running the bolt through the center of the bushing, putting the other washer on the other side of the bushing, and tightening the nut.
