A frame camber adjustment

[Rockettvr]

Hi all
Following on from my previous post one of the things highlighted by the mot was uneven tyre wear on the rear of the wedge. My 350i has alot of negative camber on the rear so the tyres are wearing a lot more on the inner shoulders than the rest of the tyre. I've got adjustable springs which are set quite low ( im going to raise this up a bit) but I'm pretty certain its not the root problem . I've got polybushes fitted by a previous owner and the rear suspension probably wasn't set up properly after they were fitted. I know on Jags and trailing arm tasmins where the drive shaft is used as an upper link the camber can be set using shims under the drive shaft diff flange but how do you adjust it on A frame cars is it the same or is there adjustment on the a frames themselves ??
The bible isn't very helpful and until I can get to my garage and fix the sticky starter motor I cant get the car up on ramps and have a proper look myself.
Any help is more than welcome
Thanks Ron

I was just under mine today in that area and there is an adjuster on the lower wishbone.

However looking at the parts catalogue it's only on one end so it looks like a toe-in adjustment.

So I suppose you need to add shims to the driveshaft, as per the trailing arm setup.

Correct bye a pack of jaguar shims and add shims to set camber

Looking at the geometry if you had to set the toe-in it would adjust the camber a little bit, so if you think that needs doing too, do it first before the shimming exercise.

Best to check you can crack all the driveshaft nuts open a little bit too, sometimes they can get rounded off or corroded, before you start.

On the trailing arm suspension, the camber gets larger as the springs start to sag, causing more tyre wear on the inside edge. Been there.
It's built in to the design. Knackered bushes tend to cause wear across whole tyre, but worth checking anyway.

Don't know about the later wishbone setup.

Yup, you need to add shims between the brakes and the driveshaft.

Mine were a right bugger, couldn't get the nuts off on the disk, ended up using the blue spanner.
