NON captive, upper control arm bolts...
Guys, I started pulling my front end apart today. I don't have a slide hammer and was wondering whether I would have the room to get the upper control arm off the "captive" mounting bolts.
When I started undoing the first nut, the bolt spun too and I had to try and hold the bolt while I removed the nut. I ended up putting a spanner on the nut and undid the bolt with a socket and ratchet. The second bolt was the same.
When I removed both bolts, the knurling that is supposed to keep them captive is worn/chewed over so that the bolts slide in and out of the hole now. They're a snug fit and not sloppy, but certainly not captive any longer.
Will that be a problem when I put it back together? I mean, is it imperative that the bolts are captive?
Thanks in advance for any info...

Thanks guys. I'll get some new ones, but I couldn't really see the old ones being a problem. I wouldn't have thought that they would move once they were torqued up...

Those bolt holes are hogged out and the new bolts will continue to turn.
I brazed the 2 bolts on the drivers side. Holes where hogged out too much and new bolts continued to spin. U could weld them instead but u would no be able to adjust or reweld the bolt as easy as brazing. Downside of brazing is once u braze it u can't weld that steel again - have to cut it out and weld in new steel.
Please becareful of the fire hazard - close to brake lines and somewhat close to the EVC.
Use fire blankets.
Sorry for the bad news but thats what i did.

I can get new bolts so I don't think I need to be welding anything just yet. I still can't see though, how they would spin when torqued up to 50 ft lbs? I think I'd even run lock wire holes into the bolt heads and nuts and lock them that way before I started to braze or weld anything...

I actually just used a set of old wheel studs. The other alternative is to tack weld the heads from the back side.
The wheel studs are the same 7/16 thread and are knurled to the right size.

the only thing with using old wheel studs is they are slightly shorter then the original bolts. I used the wheel studs because I don't use alot of shims and they are certainly long enough. That and I had alot of them when I upgraded the wheel studs to 1/2 inch.
