I am trying to remove the lower rear damper bush I have made up a tool using sockets and threaded rod to get it out as per the post on here. Soaked it with plus gas applied heat albeit it's not a big blow torch just one of the butane canister units and in desperation hit it a few times it won't budge.

The threaded rod it's M12 has now stripped albeit I have plenty.

I am at the point that I can put it all back together however if I do much more I might destroy the old bush completely and then not be able to but it back together to drive it to a garage to do.

I hate being defeated so appreciate any ideas on how to get the bush out

 

Not specific to your bushing. But, some guys will burn/char a rubber bushing with flame if it is being stubborn. Usual safety precautions around flames and flammables apply.

 

The problem with this bush is it has a steel sleeve around the rubber and that's what I reckon has corroded in the damper.

 

So, drill holes in the rubber along the same axis as the bolt. Knock the rubber bit out. Hacksaw the steel sleeve along the same axis to relieve pressure. Squeeze out.

Or apply pressure with your tool. Then, bang against the outer eye of the shock with medium force. This usually breaks the corrosion and each bang the seized part will move just a tiny fraction, but it will move in the right direction. It's the same reason impact wrenches work so well.

 

Air chissel to cut the sleeve and drive the bushing out all at the same time. I did some this morning

 

Plums I had thought of the hacksaw approach just a bit worried about damaging inside of damper sleeve. Maybe try your other idea first.
Brutal I only wish I had a compressor as I am sure it would make many jobs easier.

 

You don't need to saw all the way through if you are nervous, you just need enough to weaken it then you can either drive or draw it out.

 

exactly.

The apply pressure and bang is easier though

 

There are plenty of inexpensive air compressors. If you have Amazon Prime, this 3 gallon compressor is $75 shipped:

Take the whole shock/spring assembly to a friendly local workshop and ask nicely to press out, may have to grease a greasy palm,if your not experienced at cutting/chiseling.
Because you still have to get new one in and if you damage the bush housing by bashing it, your gonna be fu*&%D.
Or try threaded bar with finer thread

 

Buying the compressor is the easy part. But some people have no place to put it.

 

BLASPHEMY!!! Men can always find room for tools.

 

Ok, double entendre aside, tell that to the landlord
