Rear suspension problems

[steviet]

Any help appreciated
Problem with rear suspension sitting lower at one side
Recently replaced both springs
Car still sitting down lower on one
No self levelling suspension
It is quite noticeable as car taken for 4 wheel check and garage said they could not carry this out due to the difference in ride height at NSR and OSR

Have you checked the condition of the subframe mounts?


That's the donuts at the end of each sill(under the triangular plate) and the diff mounts at the back of the diff. Those are the second place to look once you've rechecked the springs

Also check the shocks, as these can affect ride height.

You did put the rubber pads back, after changing the springs.

I bought a pair of Suplex rear springs from an auto factors a couple of years ago. Although identically labelled and marked, when placed side by side, one was about an inch shorter than the other. I returned them and got a matching pair which I fitted.
Probably a bit difficult to check this now as the new springs have been fitted, but worth considering if all other checks fail to find the cause.

hi. any progress with this. did you find the cause ?

[steviet]

No still work in progress

IIRC Terry had a top shock mount disintegrating, but I would think this would be fairly obvious.

I did indeed, but the spring mounting was not damaged so ride height was not affected, and the shock absorber made quite a racket banging about in the boot.

Would anyone know what the rear ride height should be on the saloon?

Height can vary due to age of springs, shocks etc. My 3.2 always sits a bit lower than my old 2.2 did (self levelling removed on 3.2)

Have you checked both shocks? Along with rear donuts has suggested?

Yours has nothing to do with age... Self levelling springs are softer than non self levelling ones... Without the air support it probably sits 2-3" lower

[tunnie]

It's on standard springs.

[Doctor Gollum]

Saloon ones?

[steviet]

Checked both new springs off the car
Checked donut bushes all ok
Checked diff mounts all ok
Still have same problem lying lower at n/s/r
