How many miles had they done?

What state is the otherside in?

Looking at that, that may be due to the poly rear....   ....as feared

Arm could have been made stronger by welding all the way round the bush location. No evidence there of it having ever been joined at the flat surface

For reference/comparison, my o/s rear bush mounting...




 

[05omegav6]

Judging by the rust, they have been almost failed for some time

[razzo]

been on for about 2 years & about 45k driving mostly in London & home counties so plenty of speed humps & dodging other suicidal motorists but when i fitted them handling & tyre wear were hugely improved so not giving up yet

Al do you have the ring welded all round it as i think these were just tacked at 6 & 9 oclock & if so where did you get them from

[05omegav6]

Mine have been in about ten months, 21k. Arms are pattern ones, and I think have almost continous welds. From memory, they're Firstline, but obviously have been polybushed at both ends.

Have a set of arms from ATP in germany, which are un branded, no markings at all, and look very similar to yours... quite rusty where the welds are... easy to see looking at them how they could fail with stiffer bushes

There are differences between the various arms I have fitted, they way that bush ring is fitted being the obvious item.

I would suggest buying from your local factors and if necessary, have someone weld a continous bead around that ring

Might also be possible to weld a strip around the arm to form a box section to strengthen the arm further, but clearance around the back of the rear bush could be an issue with that

The other thing I will say is that the rear polybush I have fitted is totally different to yours, so not sure how exactly they compare

[chrisgixer]

I have some rather scabby articles in the garage, so scabby that pics don't show where the weld ends and the rust starts, but they are GM with the white print still showing on the metal work.

The weld is still at 6 and 9 o'clock, but the length of the Weald is much longer covering 45degrees of the circumference in a (  ) fashion. So considerably more weld present than those failed.

To me that pic makes the point that any replacement bush should be based on a ball joint design. As the original. As unhelpful as that may be, is it worth the risk...?

snapped at the rear housing, fortunately i was moving less than walking speed as i was parking the car 10 mins earlier i was at 60mph on the A13. Wishbones are 2 years old & aftermarket



got a refurbed pair to ready to fit just not sure i trust em

I'd very much suggest that that fracture has been a long time coming!  Judging by the rust on the split, it has been open to the elements for a while.

I had a very similar thing happen to me with a Bilstein Shock which sheared at a particularly sharp corner.  Fortunately, nothing else was damaged and I was able to get the car on a recovery truck.

Indeed... when was the last MoT?

Whoever is selling those wishbones wants putting out of business imo.Thats scarily dangerous for something two years old.

[05omegav6]

Have been keeping an eye on mine due to concerns about the effects of a near solid bush, and so far no signs of imminent failure and damage/cracks/tears.

Looking at that one though, they've been cracked a while, the only clean part being the upper forward side of the arm, which would suggest that three pieces of metal have failed unnoticed

Razzo was testing a different bush, but there was a school of thought that it may reduce how well the wishbone could pivot, hence may have caused extra strain/fatigue on that area.

Until he is able to try it on a better quality wishbone, we'll never really know, as it may be a genuine wishbone fault, or that that wishbone was not up to the demands of the different bush.


Razzo - have you had the opportunity to closely inspect the other side, is there any worrying signs there?

[chrisgixer]

The alternative bushes are visible in the pic, btw.

not had a chance yet but both wishbones will be removed at the weekend

car was MOT'd in january

[05omegav6]

So nine months from fine to totally fubar

Keep us informed

[YZ250]

When I posted on ABS regarding poly bushes a few years back, a couple of the guys on there said that they would not use poly bushes on wishbones any more due to snapping them.

Sorry that I can't offer any more info on whether it was just one bush fitted or both, or even what car they were fitted to.
