Guest Posted July 28, 2017 Share Posted July 28, 2017 Hey all, Bit of a problem. Mechanic has just spent the last 4 hours trying to get my old front lower rear arms / banana arms off to replace them. Unfortunately the bushing seems to be seized onto chassis bolts, and he isn't sure if there are any options aside from trying to cut it off, which could damage the chassis bolt and require fabrication to fix.... Pictures below for what is seized and won't come off. Has anybody else experienced similar? I can't believe I'm the only one who has had this problem as the arms are a fairly common issue as I understand it. Any thoughts? Input appreciated as it's currently looking like a relatively quick and inexpensive fix may become alot more costly Quote Link to comment Share on other sites More sharing options...
ZMANALEX Posted July 28, 2017 Share Posted July 28, 2017 Common fault mate. Best advice that I can give you is go find a competent mechanic 1 Quote Link to comment Share on other sites More sharing options...
Guest Posted July 28, 2017 Share Posted July 28, 2017 I believe him to be competent, he is employed by a race team that competes around europe in addition to having his shop, but in his words he is not a fabricator. He is dubious of cutting it off and damaging the chassis bolt and surrounding area which may then require work to reconstruct. Just trying to discover if anybody else has had similar problems, and whether stuff needed cutting, or whether they've always managed to pry them off? =) Quote Link to comment Share on other sites More sharing options...

When seized I either use a puller to get if off, however if your man does not have the correct tooling for the job then a bolster chisel between the chassis leg and the bushing will get it moved the first few centimetres and then work of using a large pry bar.

Guest Posted July 28, 2017 Share Posted July 28, 2017 Thanks for help Alex =) He and assistant spent several hours trying to unseize and using large pry bars to loosen to no avail. Is it a case of more force required? Is there any risk of bending the pin and buggering up the geometry as a result? Would the chisel not damage the thread, or is the thread on that part of it not important? Quote Link to comment Share on other sites More sharing options...

Using a bolster chisel at the top of the bushing will move the bushing down a few centimetres and you will then get in from the top with the release oil. Then using the pry bar evenly, you will be able to work the bushing off the pin. There are no threads at the top of the pin so the threads can not be damaged. Any resulting damage however will depend on how ham fisted your man is. Quote Link to comment Share on other sites More sharing options...
MDMetal Posted July 28, 2017 Share Posted July 28, 2017 would a ball joint separator fork help? different issue but a caliper slide rubber got stuck on the missus car and I ended up melting it slightly.... The rubber will melt before the metal. Quote Link to comment Share on other sites More sharing options...

If the correct tooling is not to hand then the bolster chisel is the best option to move the bushing down a tad to break the "seal" and create a gap.

MDMetal Posted July 28, 2017 Share Posted July 28, 2017 I just whacked mine with a hammer and a piece of wood, that said I didn't remove the hub side until the body end had been shifted to ensure there was no twisting. How deteriorated is the rubber? I had a qashqai engine mount disintegrate in my hands after some prodding with a screwdriver Quote Link to comment Share on other sites More sharing options...
Guest Posted July 28, 2017 Share Posted July 28, 2017 Brilliant, thanks so much Alex, really appreciated =) MDMetal, the rubber doesn't appear to be about to fall apart in any way, if it were I can't imagine there would be a problem! =D Quote Link to comment Share on other sites More sharing options...
MDMetal Posted July 28, 2017 Share Posted July 28, 2017 all together it might appear solid but often taking it bit by bit it's less strong,anyways good luck! Quote Link to comment Share on other sites More sharing options...
