I own a 2011 model Saab 9-3 Biopower linear, 147kw with 5 speed auto cabrio. The car only has 60,000kms on the odometer to date.
The car has been running great but a couple of months ago I decided to lower the car for a more aggressive look and sporty handling.
I've fitted H&R springs (40mm drop) with Bilstein B8 dampers front and rear. All codes match up to my car.
Two problems have emerged:
a/ A slight modulation or wobble from the left front wheel at around 20 km/h emerges and then clears itself as you increase in speed. When stuck in traffic its very annoying.
Yes, I've balanced the wheels and checked rims for any buckling, I also replaced the CV shafts with new units, thinking this was the problem.
I've also replaced the front shock absorber top bearings and mounts with new.
b/ Steering has no feedback and is very light now. It is virtually effortless to turn when at an intersection but the real safety issue is at highway speeds say 80km/h and above. The steering feels incredibly light and vague which is causing me to over correct when changing lanes, not pretty. If your not aware of the sensitivity you could easily flip the car. Its as if there's far to much play in the under carriage and it needs to be tightened down. However we have gone over this with my suspension mechanic twice and everything is torqued up correctly. Nothing is standing out as to the cause. Also let it be known the handling of the car prior to suspension mods was perfectly fine.
Does anyone have an idea whats going on here? Frustrated 9-3 owner.
