rear suspension

Hi All
Does anyone know if the rear suspension arm on my 2.3 ultima has any adjustment?
My rear nearside wheel seems to be suffering with too much toe-in, as tested with a piece of string drawn taut from front to rear wheel.
The other side is fine!

Could be the rubber bushes between the arm and rear beam or the rear beam to body mounting bushes 
Are you getting uneven tyre wear ?

Funny you should mention tyre wear Mike! Normally the both rear tyres wear on the inside(which is normal according to my MOT tester due to the negative camber bias on the rear of the scorp)
But my nearside tyre he described as 'mishapen' and has very little wear on the inside?

This is news to me! Never even knew it had 'negative camber'
The 'piece of string test' is something I remember from a Haynes manual for some old motorbike, tried it once or twice, VERY tricky to get any accuracy as it totally relies on the tyre walls being absolutely even. So probably doable with 'skinny tyres' but wouldn't trust it on 'fat' car tyres, or even a modern bike with 'fat' tyres.
Actually the latter wouldn't work anyway as rears tend to be wider than fronts.

PS: had need to renew a rear earlier this year, IIRC was pretty much down to minimum more or less evenly all over. If there was any emphasis think it was toward the outside, but memory is now hazy. Which doesn't take long

Rear tyre wear should be even across the width of the tread - at least that has been my experience - unless you are maybe doing some 'Top Gear' style cornering 
I still suspect worn bushes...
I had a Sierra XR4x4 a few years ago with the n/s rear tyre worn badly on the inside - I bought the car as a project donor and when I dropped the rear suspension off found the n/s beam to body mounting had failed which I can only assume caused the n/s rear wheel alignment to be incorrect.
