HELP!!! Top of Subframe Bushing Broke Off in Chassis

[longms]

So I did the old lag screw and pound method to break the subframe free from the unibody but the top part of the bushing (part of metal sleeve that sticks up and goes into the body) broke off inside of the body. I tried doing the lag screw method again with no luck. My next step is probably drilling it out but I want to try to avoid that. Any ideas?

My car has won most of the battles but I plan on winning this war. Thanks ahead for the help.

Subscribed as I will probably will have to go through this crap since the bushing on mine is stuck.

Getting it to break loose isn't that bad. I went and bought a 4lb mini sledge 2 5/8" lag screws and a 1/2" x 1' bolt. Screw the lag screws into the bottom of the old bushing and stick the 1/2"x1' bolt through the pin hole and bang away. The only problem for me is that the top of the bushing broke off in the hole. FML!!!

How did it not work? Are you unable to get it to pound out, our did you pound just the screw and "threads" out, leaving the broken off stub still there?

If it's the former, keep pounding, and if it's the latter, get a bigger screw, then keep pounding. When I did mine I didn't use a lag screw, just a regular bolt driven in with an impact wrench.

I think I ended up chiseling out the old sleeve.

Pm sharkey. He just went through this last week.

Soak the stub with PBlaster or Kroil for a couple of days. If you are lucky the lube will allow the stub to come on out. If not, tap the hole in the stub, thread in a bolt and use a puller in conjunction with a drift driven from above. The stub will come out then.

If you don't have a puller, use threaded rod and a sleeve that will fit over the stub. Then a plate and nut on the sleeve.

Same thing just happened to me today. I tried driving a wide chisel into it and twisting it, but it just mashed up the aluminum and fell out. I don't think I'd be able to properly tap it and thread a lag bolt in to pound it out, because of how mashed up it is. I sprayed it with PB blaster, I'll give it a shot. I may resort to using a dremel grinding wheel to careful grind it out. what a PITA.

I've had this happen twice. What I always do is just drill into it over and over again until I can break it up and pry it out.

I ended up using a grinding bit on a drill to thin it out, then broke it out with a chisel.

[Cinnabar325is]

Ha, this just happened to me too. Haven't attempted removing it yet.

[MaxBell]

Wow, and I thought stuck subframes were bad.

[longms]

I ended up uses a gigantic drillbit and slowly drilled it out and then applied pressure around the sides and then eventually it just comes out.

Just did mine today, that looked just like mine did. I dried a slit on the side and got bigger and bigge with the drill bit. After the slit was open I took a chisle and spun it out/broke it up. Goodluck
