pounding out subframe mounting stud with seized bushing collar

[irish44j]

My subframe bushings were so thorougly shot, they dropped with almost no effort. In fact, they completely seperated and dropped right off of the inner metal bushing tube, as can be seen in the pic below. Since I don't have jaw-pullers quite long enough to reach to the top of the upper washer/bushing stop, and the inner collar won't break free using other tools I have handy (without improv'ing), can I just smack the bottom of the stud with a BFH and drive it upwards into the car, which should drive the inner bushing off of it?

I'd wait and find a larger puller. I'd be afraid of knocking the stud loose from the car, but not breaking the sleeve/stud bond.

Hit it with a butane torch too.

for the stud to come loose from the car, it would have to break the sleeve bond, else the stud wwouldn't go up.

not sure I want to play with the torch that close to the fuel filler line, lol...

I suppose I could also just put a floor jack under the stud and push it up using the car's weight...hmm.

Yes, you can. I would get something to catch it though as occasionally I have heard if you hit them hard enough, they will shoot up and hit the rear windshield.

Not sure what you're worried about--if the stud is out and the sleeve is still frozen, just whack it.

excellent idea. especially with the new PPG glass back there (thanks p/o!), lol.

not "worried" per se, just wanted to double check and make sure there wasn't something I was missing before I do it. (like a circlip holding the stud in or something else random like that).

Working on older cars for so many years, I am constantly surprised by the creative/inventive/unsual ways manufacturers do things that make no sense at all, lol.

Got it. Good luck--it's not too bad. I just buttoned up everything on my subframe job, haven't set it on the ground yet though.

[irish44j]

cool, yeah once that's done and the new bushings come in the mail I can put it all back together (with new brake lines, 325 rear discs replacing my drum setup, etc). Only thing left to find is some disc brake ebrake cables, since my drum ones won't work.

heat the aluminum sleeve that is stuck on the stud then turn it with a big set of pliers and stick a chisel between the top of the sleeve and the body of the car, it will come loose i've done three cars this way
