SteveW Posted July 30, 2014 Share Posted July 30, 2014 So tonight I started removing my banana arms to fit some Superpro bushes. All went well until it came to removing the driver side arm from it's mounting stud. Basically it seems the steel inner sleeve of the OE bush has corroded itself to the mounting stud. I've hammered, pulled, pushed, covered it in plusgas, wd40 and then waited pulled pushed some more and it still won't budge. Any ideas how I can get this off? Thank you Steve Quote Link to comment Share on other sites More sharing options...
Jixaman Posted July 30, 2014 Share Posted July 30, 2014 Could try a tin of Metaflux, wouldnt hold my breath for even that though, if there put on without lubrication there bound to fuse, just mind to cover the pin with a non copper based grease when you put the new one on... Oh and the bad news is its usually easier to take the grinder to them (both mine had to be done like that)... Hope you get it worked...

Lexx Posted July 30, 2014 Share Posted July 30, 2014 You could try some heat in the hope that the metals expand at different rates. Quote Link to comment Share on other sites More sharing options...
gareth29 Posted July 30, 2014 Share Posted July 30, 2014 would one of those forked ball joint separators go between the chassis and the top of the arm and let you force them apart? Quote Link to comment Share on other sites More sharing options...
Jez @ H-Dev Posted July 30, 2014 Share Posted July 30, 2014 If it really stuck we've had to get the car in the air, weld on a piece of 1" box section tube to the central part of the bush and hammer it downwards. Sometimes they can be really really stuck on. Quote Link to comment Share on other sites More sharing options...
marzman Posted July 30, 2014 Share Posted July 30, 2014 Plus Gas takes time. I needed to remove the backbox on my 911 last month, and i was swinging off the last nut for about an hour with no joy. A week later i came back to it, and it came off really easily. Quote Link to comment Share on other sites More sharing options...
SteveW Posted July 30, 2014 Author Share Posted July 30, 2014 Thank you for the suggestions. Sadly I don't have a welder or a ramp as I think that would be the easiest. I'll keep plus gassing it, heating it and giving it a tug over the next few days and hopefully it'll penetrate and come loose. If it doesn't I think it may have to be a garage. Jixamam How did you go about grinding the bushes? Through the rubber at the bottom and into the sleeve inside? Would have to be careful not to damage the shaft the bush slides on.

SteveW Posted July 30, 2014 Author Share Posted July 30, 2014 Sadly Gareth that wouldn't work, I've been trying to get a chisel in between the underbody and bush without success. Quote Link to comment Share on other sites More sharing options...
Jixaman Posted July 30, 2014 Share Posted July 30, 2014 No, sorry, I did the whole arms as the ball joint is the same age as the bush... Cutting was more than an option in my case... I cut the arm and the rubber and took the grinder to the sleve... But try this... Drill the rubber, take hacksaw blade, cut out the rubber, that removes the arm then grinder to the sleve, just be carefull not to cut too deep, not pretty but that arm has to come off...

Agh yes that now makes sense. Ball joint seem to be in good shape so just doing the bushes at the moment. Good shout on cutting the bush. I was thinking it may be easier to destroy the bush to get the arm off then I can at least fit the new bushes and get the mole grips and grinder on the sleeve.
