Hi All 

 

Have the rear subframe out the car to rebuild, while i'm at it I thought I would replace the bushes but for the life of me I can remove the rear ones from the frame. I have of course undone the big nut which hold them to the frame and they will wiggle round but when I try pull/hit the rear subframe support pin it will not come out. 

 

Any tips would be great as this is driving me mad. 

 

thanks in advance

If you have a good vice which is bench mounted would help

 

The pins rust onto the subframe as there is not a lot or wriggle room.  What I have done is put the head of the support pin in the jaws of the vice - then rotate and chatter the support pins, twisting the subframe back and forwards - side to side.  You can use a bit of heat, just be careful obviously

 

Putting the head of the support pin in the jaws of the vice does require the subframe stripped of everything - so you are only wrestling with the pin and subframe

 

They are a pain - I am sure a few other members can add their techniques of how they have got the pins out - this was mine.

thanks for the reply. 

 

I have bought new poly bushes for the subframe but feel like it might be more hassle than its worth to replace them. 

 

Will try as suggested and report back

Spray liberally with penetrating fluid (PlusGas or similar) and then use good grips to get the pin turning - keep working it until it turns relatively freely.  Once it does use the grips to turn and pull it at the same time.

 

I would certainly replace the bushes if you're this far in - they do degrade over time and will not be holding the subframe as securely as they should, compromising the handling. Personally I wouldn't use poly bushes here.

Thanks Graeme 

Just out of interest why would you not use poly bushes? I'm a bit of a novice here and just bought them as thought they would be better. 

[GraemeC]

They simply are just the wrong material - not compliant enough and tend to permanently deform.  Effectively they give plastic deformation rather than elastic.

 

Lots of thoughts on the forum, one thread here:

quick update

 

after soaking it with penetrating fluid and wiggling, twisting and pulling on it I have finally got one side off.
