i just bought another stang and i am tryin to change out the rear lower control arms. the bolts rust into their sleave for the rubber bushing. is there any trickes to get them out easy? i tried heat but i would like to do my torque boxes while im down there so i dont want to beat the hell out of them.

 

pb rust blaster works wonders

spray and let sit and then respray and let them sit a while

keep spraying them if it doesnt work at first. there has never been a bolt i havnt been able to get out with that stuff

any local autozone or somthing should have it

 

+1 on the pb blaster, i used an air hammer for all my bushings

 

i tried that. the problem is that the bolt rusts to the sleve in the center. i cant even spin the bolt at all. i let my impact sit on it for like min and didnt even budge. i tried heat and that didnt work. if i put on a huge 5ft sissy bar i can turn over the whole bolt and bushing sleave. but most everyone here has change control arms so someone out there has to know how to get them out.

 

like i said air hammer

 

Well from my knowledge heat expands metal, thus making it bigger, I dont think that it would contract that much when it cools especially when rusted. I think the rust actually acts as an insulator. We use this stuff at work, I am not sure what it is called. I think its coroil or something like that. I would try soaking the bolts and letting them sit for a bit.

 

if you can get your hands on a sawsall you might be able to get in between the control arm and the torque box and just cut the bolt off flush, then just pull it out and replace the control arms

 

i have a sawsall but i cant get behind the head of the bolt. but i dont have a air hammer. i just picked up a balljoint press and i am going to see if i can force it out with tht because i just broke a c-clamp tryin to force it out, this is just a beefer one. anyone have other ideas please feel free

 

dont bother trying to get between the bolt and the box... get between the box and the control arm

 

Liquid wrench soaking should do i I dunno how that reacts with rubber/eurethane though. Check the bottle.
