My front lower wishbone cracked all the way through the weld apparently from the inside as they seem to rot. Happened at 70mph which was interesting to say the least. Thankfully it held together until I reached the dealer where it promptly caved in to the wheel arch thankfully with no body damage to myself and my wife or the car. Took one hell of a time before I trusted it again and over a year before my wife would go anywhere near it!

I replaced both and the new ones were of a different design and think may have been supplied to the factory by Simon.

First time I’ve heard of this.

Scary

Assume this is an expensive job

I had a front lower wishbone crack at the inner weld. No real sign of corrosion. Luckily it was reversing out of the garage when it failed so no damage but difficult to get back in without causing any. Replacement wIshbone prices from Morgan were reasonable but it is labour intensive to change.

Is this an issue that is found on a particular Series does anyone know or across all 5? I have a Series III (2007) which has recently been to BHM for a full service and SSL suspension kit so would like to think that any potential issues would have been spotted at the time, however if they appear to rot/crack from the inside it may not be something that can be seen until it's too late!


Cheers, Paul

I've only seen the Series 1 wishbones fail, but that doesn't mean it wont happen on the later cars

The lower front wishbone typically fails where the caster rod bracket is welded on (circled in red) with the crack rotating around the tube

These are a set I reinforced for racing years ago in the same way we did for the British GT car, by welding in additional sheet metal to prevent the wishbone from lozenging.

The top rocker arm fails around the pivot tube boss

The rear lower wishbone likes to bend where the coilover is fixed to it

Simon,

Have you seen low mileage ( Road miles ) failed or it more concerning racing cars and big mileage?

We only ever had one wishbone failure on the race car because they are checked more regularly …

I’ve seen several on road cars…

Looked up the bill for mine and in July 2019 one wishbone was 344 including VAT and looks like 3 hours labour to fit so all in was 560 quids! Times 2 that if being on the safe side which I was. Seemed like a lot of money until the next bill of 2.5k which included so much it was like reading a book!

Still I’m sure the next custodian will thank me even if the wife thought divorce was a cheaper option.😁
