W203 lower at one corner

[lexuscol]

Hi My c-class is sitting lower atthe N/S rear corner, I have checked the springs and even swapped them side to side, I can't check the shockers as they won't budge suspect they are gas filled and not oil.
All the arms are straight and the bushes are fine. No excess weight in the boot.
I measured the car from the centre of the wheel to the bottom of the wheel arch and found no discrepancy at the front but the rear is 1/2 inch lower at the N/S.
Anyone got any other ideas of what to look for??
Car drives and handles OK.
Thanks
Col

check the tyre pressures

Well, if the swapping the springs didn't get the result, then it might be the coilovers that is damaged.

I have a similar issue. I had both front coil springs replaced and now the right side sits slightly higher than the left. Just what are 'coilovers' anyway
