wishbones

[mmmmm]

i put my 93 chim in for mot and it failed on a rusty wishbone, i had only done 3k since last mot and was horrified to see the state of it. it had rusted right through on one side cracked almost through on another, wouldnt like to have had it go on me !!!!
check your bones!!!!!!!!!!!!!

Yes, they rust like buggery - my 97 Griff has had a sheltered life yet the wishbones look like bits of old angle iron. I've wirebrushed off the crud and sprayed Waxoyl over them, but it's clear they're only going one way. Perhaps someone could make stainless wishbones?

The ones that same off my 94 Chimaera a few months ago were a sad sight, the 'metal' was wafer thin in some parts, it doesn't bear thinking out what 'might' have happened should they have failed under load

[s2ooz]

my 96 was the same, bought it from a dealer with welded bones. which by the way, wont support it. ranted unitl they replaced them, car was 4 yrs old with 17k on the clock..

What's the average price of having them replaced, is it easy to do yourself.

I had all wheels off the other week for a good clean, happend to inspect my wishbones. Not pretty..

I don't think stainless wishbones would be possible, too brittle.

[monaghaj]

Stainless steel is not a brittle material and would probably be OK. The other options are to galvanise them or coat them in a polymer type material (e.g. epoxy paint).

Why can't TVR do this?

I'm seriously thinking about having any replacement wishbones hot dip galvanised and painted before fitting. When I get some information about costs I'll post them here.

My wishbones needed replacing by the previous owner, and who ever did the work (Mole Valley I think) painted them with something. Its a creamy beige colour, any idea what this is?

[philshort]

Stainless steel most definately has a lower tensile strength than mild steel. That makes it brittle in my view, and I'm sure any qualified metalurgist would back that up.

You mean a cream coloured paint or a waxy coating - the latter would be waxoyl or suchlike.

Peninsula make tubular wishbones with a much better adjustment method for geometry
These are hot zinc painted and powder coated much better finish and durability
Cost about £65 i think

[Marshy]

snap, how does that compare pricewise with the standard ones? My top wishbones need doing for my upcoming MOT. (Arse)

[mmmmm]

the new one appears 2 have been modified with an xtra support, it is a beige colour, hopefully more durable but still have another 7 2 go !!!!!!!!!!!!!!!!
