Oooh-Er Look At This!

[Guest ollie chapman]

Hi - Ollie returned from a spin out with his uncle - who runs a Westfield - saying "Dad, we have a problem". Some problem! The rear n/s lower wishbone mounting has fractured in the following places... good job he really wasn't clogging it!

 

Has anyone ever seen this before? Any ideas?

oh dear....i would be straight back to GBSC personally. best people to work out how that has happend, and also the best people to get it fixed for you.

That's not good, very interested in what caused it.

Happy for you that it didn't end in tears

Let us know if you find a cause

crush tubes too short causing the wishbone to twist the mount?

[speedtripledan]

that could have ended in tears ! how old is the chassis? interested to know what gbs say...

[Guest ollie chapman]

Chassis is 08, car iva'd 2010. I'll be updating you all as soon as. Thanks for your thoughts.

I would tend to agree with that as a possibility.

What are crush tubes?

[Shaft]

The steel tubes that go through the Nyloplar bushes in the wishbone ends. If you've made them too short the bolt will clamp up the tabs on the chassis hard against the bushes. This would cause

Torsion in the chassis mounts as the wishbone moves up and down.

The rust at the cracks imply the issue has been around for a while.

As above don't like the rust and if a tight bush can cause this I'm not realy impressed .Get GBS involved before you do any thing !!! my ops only

[Guest ollie chapman]

Hi guys, thanks for your posts. I have already emailed GBS and I'm awaiting their comments.All of the above is very interesting, although I would say the rust is only very light and I don't see corrosion as an issue.

[Guest ollie chapman]

Hi guys, GBS straight back to me this morning - bring it in and we'll sort it, no quibble. I'll keep you posted. Thanks for your posts.

[Guest alfaGTA]

Good response from GBS as expected, i imagine they will want to see that the cause of failure was too. Keep us posted if you can as we all have wishbones prone to failure..........

[megadodo]

I didn't say corrosion was an issue, but the paint has fractured before the tube allowing rust to develop so the "stress" has been there for a while.
