406 est rear tyre wear

GSB · Post by **GSB** » 30 Apr 2007, 12:41

The rear tyres on my 98 est are showing signs of increased wear on the outside edges. I have replaced the antiroll bar drop links. Which of the other bushes etc, might cause this?

Thanks

Can you see any appeciable negative camber (/--\) on the rear wheels?

Tyre wear like this is usually caused by failure of the trailing arm bearings in the rear beam, a very common problem now on all Pugs using rear torsion bar suspension.

The beam can be rebuilt but often it is found, especially if negative camber is present, that the trailing arm shafts are beyond salvage and the beam tube has ovalised bearing housings. Best to have a pro rebuild at around £250 or scour a breaker for a good 'un.

Once again, a built-in fault caused by water ingress into the needle rollers and a lack of a grease nipple

406 has multi-link rear suspention. Doesn't use the 405/306/309/205/106 style trailing arms/torsion bars.

If it's wear on the outside edge of the tyres, I would expect it to be one of the links that controls the rear toe.

I read the 6 as a 5
