Quick question: how are the upper control arm bolts held in place? (I mean, the ones that hold the shafts to the frame.) Are they welded to the frame? Do they have a "square shoulder", like one of the idler arm bolts? I'd like to remove those bolts (:smash:) to make the removal of the control arms easier, but don't want to screw things up...
Re: Upper control arms - quick question (Pedro'74)
No Pedro, they're not welded in place. They have a serrated edge just under the head of the bolt that holds them in place. A good blow with a brass hammer will usually dislodge them easily enough. And the same to reinstall them also.
Re: Upper control arms - quick question (Pedro'74)
Van Steel uses a slide hammer to remove the bolts. It definitly looks fabricated, but it goes in through the fender and slides down over the bolt. Then they just slide the hammer back and pop the bolt out. Of course, you'd have to have a slide hammer like theirs, but they sure make it look easy in their video on suspension removal and reinstallation.

Slide hammer, I believe, can be rented from Autozone. If not they are not really expensive or the could be fabricated. Don't "twist" the bolts as you would damage the frame and/or bolts.

Hi Guys,
Thanks for the responses. You were right: there's definitely no swinging room there. I'm not sure what a slide hammer is, but the C-clamp did the trick! :cool: I removed the front bolt only, and for all I care that's enough, since I was able to remove that filthy control arm (years of power steering leak and torn ball joint boots made a real mess in my front suspension). Now let's try the passenger's side.... :smash:
Can I buy new bolts (if so, where?), or should I keep them?
Re: Upper control arms - quick question (Pedro'74)
Glad to hear the c-clamp worked for you!
You can new upper a-arm mounting studs at pretty much any Corvette supplier/vendor such as Zip or whatever. I happended to get mine from Corvette America.

I replaced my studs a few months ago and went to the dealer to buy 4 new ones. They were about $4.00 each but I had to buy a skin package of 10. GM's new policy. I just used normal wheel studs. They fit like the old studs. The existing hole was perfect and I had some in stock in my shop.
Re: Upper control arms - quick question (Pedro'74)
I have no air or power steering, and our shrouds may be different. I recall loosening the shroud by taking out the 2 top screws and the nuts and bolts on the underside and just pushing it over an inch or so.
Re: Upper control arms - quick question (isosceles)
Thank you very much! I am glad I was able to help. My front end (a-arms, springs, etc.) goes back together this weekend. Alignment next week. Then off to Goodyear for a new set of tires. Hopefully I can fit 255/60's instead of the small 225/70's I have on now.
