159 rear suspension advice
About 3 months ago the ride in my 159 (06, 2.4 with 18" wheels) became much harsher. The dealer had a look and could not find fault.
I later noticed that it was lower in the arches in the back than the front and on inspection found that the offside tyre/arch gap was about 1/2" lower that the nearside.
The dealer couldn't understand why but ordered new springs. When they arrived he found that they were longer than the originals but checked and they were the correct spec for the car. Obviously, the originals have been replaced.
However, when fitted the car was higher at the rear and tyre/arch gap is now greater at back than front.
All seemed smooth at first but the harshness has returned with jolting over bumps and a pretty uncomfortable ride on less than perfect roads.
So before I take it back, has anyone elsee had similar experience of the ride becoming harsh or know of any explaination, please?
