Hi, I have just had the rear coil springs replaced because the 'drivers side' had snapped. However, there is still approx 10mm difference on the drivers side verse the passenger side. Both new springs are OEM so are the front springs which were replaced 5wks earlier. I believe the rear springs have 'shims' in place and was wondering if it was possible that when the 'drivers' spring snapped, I may have lost a shim? I would appreciate any thoughts /idea's on my dilemma.
