Wheel collapsed. Causes?
Went to the beach to take some new pictures. 5 minutes after I took this, while heading home, the left front wheel collapsed in at the top. I had it taken to my mechanic on a flatbed, but he's not there on Sunday, so I left it for him to look at tomorrow. In the meantime, what is most likely the cause? Ball joint?

[QUOTE=dannyman;1564471375]You had your camera and didn't take a picture? 
You're right, I should have had a picture! :o
My camera battery died while I was taking pictures of the vette. I just got back from an overseas trip last night and hadn't recharged yet. Did get one with my cell phone though...

I would say upper A arm or uper balljoint. I had this happen with a '79 i had just after installing polly bushings. I didn't know you needed locktite on the end bolts and one of my came apart allowing the A arm to slide forward off of the shaft and off of the rear bushing. What a mess.
I limped it home and put it back together. That is when i learned about the need for locktite with polly bushings. They will not compress under torque as rubber does. Re installed all eight bolt with...red locktite.
Let us know what came apart....

I had that problem. Heard a bang, stopped and the RF wheel was tilted in at an odd angle. Luckily it happened in front of my parents shop Got it on the lift and the weld holding the RF Lower A-arm to the frame had split. It was still attached by about a 1/2" of weld.
Carefully fixed it and went ahead and re-welded the other side too.

Didn't you pop the hood or look underneath right away to see what was going on? I would have, then you would know what happened. Sorry to hear this happened and hopefully no damage to major components.

Update
Just heard from the garage. One of the bolts holding the upper control arm shaft broke off. Everything on the control arm is fine.
Here's a pic after we got it off the flatbed yesterday. Thanks for all the responses folks, everybody was pretty much correct!

Wow, tha has to suck. Good thing you were not riding down the highway at 70mph. A freiend of mine broke a spindle on his 71 while he was following me down to Ky. He said it just gave a jurk to the steering wheel so he slowed down to 50 and made it to the next exit. Once we pulled the wheel off the rotor I could see it was only being held on by the caliper. Scary!

You said "broke off". Did the bolt actually break or shear? I wouldn't consider that a common failure. Could have fatique cracked on a previous installation I guess. Odd!
Glad there isn't more damage!!

Sounds just like mine. Did the bolt break or back out. If you have polly bushing you need to take each endcap bolt out, locktie it and reinstall.
I never heard of one just breaking. Can you get a photo?

This has nothing to do with the bushings being poly or rubber. If the bolt holding the bushing to the shaft broke nothing will happen unless the bushing walks its way out of the control arm. It sounds and looks more like the shaft to frame bolt broke and is allowing the shaft to move inwards causing the wheel to fall inward.

It was explaned to me by a manufacture that the polly bushing will not clamp up with torque as the rubber does due to the fact that the polly will not compress.
If in fact the/or a bolt broke then you would be correct in stating it has nothing to do with the bushing material.

I saw something very similar looking to this happen to a friends '69 Chevelle about 25 years ago.
Turned out the alignment shims on the left upper control arm had somehow fallen out.
