Control arm bolt just spins help....

So the other day I was driving to work and out comes a deer I smashed a doe at about 65 mph. It took out the passangers side front fender, headlight and bent my control arm an inch back and it rubs.

I started to take everything apart so I could get it fixed. The fender came out just fine but totaly bent the bolt holes so that may be another topic.

So here is my issue, I started taking the control arm off, got every bolt out except the rear bolt, I believe it was a 21mm socket. (Closest to passenger side door) I turned this bolt for hours and nothing still harder then ever to turn. I had my father in law have a crack at it while i stuck my hand behind the frame where the bolt goes and it does not spin while turning the bolt.From what i understand there is a cage bolt welded to the frame maybe thats an issue.

Im afraid when i hit the deer it snapped the bolt inside the bushing. So I'm out of ideas what to do. I'm unable to get any kind of tools inside this area as its almost totaly enclosed just enough room for my fingers.

I added a few pictures of the damage to car. I didn't think it would snap a hardened bolt. Please someone help me out with this I hope I explained everything correctly. I could post more photos tomorrow if necessary.

I had this problem but on the driver side….The nut holding this bolt is held in place by a metal 'cage' (its called a caged nut). I ended up removing the steering rack to give me better access to the top of the control arm where that nut was spinning freely in the cage. I broke the cage loose using long nose vise grips and then had access to the nut … using a 1 inch open end wrench, I was able to secure the nut and remove the bolt (I say again, that was on the driver side !)

Good luck

Whether the bolt is broken or not, I think you have to cut stuff. I fitted a hacksaw blade fitted into a crude wooden 'handle' to get into the tight spaces. (The driver's side is worse for that.) It was slow going, but it worked. I'm not sure my wrist has gotten over it yet.

In my case, the bolt was rusted into the sleeve inside the bushing. I had to cut through the sleeve & bolt at the top and bottom of the bushing. With that, the control arm came out. I couldn't 'pop' the cage off (lots of ppl say you can), so I had to cut that. Then I used a punch to get the top of the bolt (and the nut) out. All downhill from there.

FYI, I bought replacement bolts from the dealer. For the nut, after reading around, it looked the proper choice was a Class 10 'Flange Prevailing Torque lock nuts'. (M14-2.0)

I hope I never have to do it again.

It's not the bolt that spins...its the nut that spins in the cage because the cage and/or nut is damaged.
