What do you reckon happened to this?

[willem]

I can't work out what happened to cause the damage on the right rear suspension of my D3 (http://www.aulro.com/afvb/d3-d4-rrs/186754-project-permagrin.html#post2036820) before I bought it. The damage on this wheel is interesting:

Anyone want to speculate on what might have happened?

Looks to have had the impact from within the tyre, perhaps a hand grenade was accidentally left inside by a tyre fitter. :wasntme:

[snowbound]

slipped onto a sharp rock or something?

[bee utey]

Police road spike?

I would say that with enough force a blunt object carried through the 'protective zone' of the inflated tyre with enough force to shatter the alloy, but not pierce the tyre, unless of course you take the tyre off and examine it internally.

One of many of my reasons for not using low profile tyres, however the forces exhibited there are pretty extreme as the suspension damage shows :o. Not much could've cushioned that blow!!!!

blunt force...

I suspect that the already low pressure tyre may have been flat (unseated bead) and the vehicle dropped onto a "ridged" rock.

It doesnt take too much force to do that kind of damage to some of the light weight alloys.

I thought it might be useful to take a pic of the inside of the tyre through the hole in the rim:

Here's a bit of speculation for you. By the shape of the break in the tyre it looks similar to what I'd imagine a forklift tine to make. That is also in keeping with the size and shape of the hole in the rim.

What do you reckon?

Didn't notice a flat and hit a rock?

[justinc]

Wouldn't be the first time pondlife at the yards have done this :mad::mad:, somebody I know bought a rolled 130 at auction, had low k's and was a good repairer. Idiots stuck the tines in under it and bent the rear shaft, damaged the transfer case and let the vehicle slide back against the mast by the looks of it as the only straight B pillar and door were then bent. Added quite a bit of $$ to the repairs.

That'd do it, I've seen plenty of spoke and lip damage as well as punctured tyre sidewall from it but how the hell do you get the tines verticle enough to punch through the tread of the tyre and then into the rim?

What about the tines on those trucks that pick up the rubbish skips?


Willem

It looks to me like a suspension failure. Similar damage has previously been reported here relating to D3s.

I thought that at first but looks like from wrong angle.

Simple suspension failure doesn't result in holes in the wheel like this. Besides the damage is all wrong. The rear tie rod was ripped out of the chassis bracket, not broken off at the hub.

Drive the spike into the rear of the tyre!


yeah but then the hole would be across the rim not along it...

no but abusive driving could cause the tyre to fail first and then the suspens ion damage to occur OR the loss of control at a critical moment from the suspension failure could result in the wheel being placed in a poor way.

Ockham's razor

among competing hypotheses, the hypothesis with the fewest assumptions should be selected

vehicle was driven over an obstacle resulting in a damaged tyre, rim and suspension components.

Clearly you have never had to deal with murphy and muppets at the same time.
