Laguna mk1 Rear Suspension

I have a issue with the Rear Offside (Drivers side) suspension.

The problem is that all of a sudden this side at the rear has dropped and is now lower than the NearSide.

I have just changed the shocks thinking that it could have been this, an after changing them it seemed as though it was higher again. I then moved the car forward and now it has gone lower again.

What could be causing this to happen? I have looked about underneath and cant see anything that looks a miss or broken.

I have not driven it since changing the shocks today, but previously it was pulling to one side when braking. I have bounced the suspension up an down and it seems ok.

Could the rear suspension bush cause this drop in ride height on one side.

Re: Laguna mk1 Rear Suspension

Hi, how's it going?
Whats the set up on the laguna? Does it have coil springs?
If so it could be broken. I am not familiar with this car but i think ride height is usualy governed by springs. Also the bouncing test would prove the shock to be ok.
Was the height ok after being lowered off the jack? And went down after the hand brake was taken off? Thats normal even in a healthy car.
Check the springs, specialy in the lower seating as they can rust there and sometimes break, one or two coils would mean a noticable drop in height.
If you have a link to a diagram of the setup please send it to me.
Best of luck.

Torsion bar broken i guess. Could be swapped though but maybe the other one carrying twice the weight might have gone twisted too. Of course if this is Laguna I. Laguna II has springs.

The mk 1 Laguna has a torsion bar. Unfortunately as it means fixing probem is a lot harder that just changing a spring etc.
