weird suspension problem

Hi all,

yesterday when approching my car I noticed that on the passanger side, the wheel gap between tire and fender is huge ! I can fin 3 fingers ! But on the driver side, the tire is flush with the wheel arch ... Did I broke something ?! Looks weird when walking around ...

My car is dropped on "blue spring", so I guess it's the famous Koni Sport everybody talk on here...

Thanks for the help !

Sounds like your car rolled back on the e-brake, which will raise the side the brake works on.
Mine used to do that all the time.

park it level with the Ebrake off, and see if it happens still.

That's true, I did that a long time ago ...

I never used the Ebrake since that time. At school my car is always parked level (ciment slab) and my passenger side is still up !

Time to visit my saab specialist I guess

Hard to tell since I'm supposedly dropped ...
With Koni 'blue' springs how low the car is supposed to be ?

I'll take picture later today. Thanks for the replies !

if it's lowered at all, I'm guessing it's high on one side. my B&G's left almost no gap.
it's more likely that your spring has somehow come off the perch/seat.
I bet if you got on the ground and looked up, you'd be able to see the issue.

As promised, here's some pictures I took today :
Driver side :



Passanger side :


It may not be the best pictures but it gives you the idea how big is the wheel gap. (Yes new rotors are comming)
I'm getting under it this weekend ...

I feel like this large gap thing happens more often than it should. Some people have posted about it before.

Well I searched a lot during the holidays and found nothing interesting ...

So I jacked the car and took off rear wheels.






Coil are not cracked (but rusty), KYB doesn't leak and rear axle seem straight ...

I will replace my rear shocks and see if it helps ...

Koni or Bilstein I'm still not decided yet.

Hope everyone had a great xmas

Check in the trunk areas to make sure that your rear shock on the low side isn't punching through the mount hole. Perhaps the shock mount has rusted out on one side and is allowing it to push the shock through. Its a common issue and from your pics I can see the top of the shock on the low side and it seems to be sitting at an odd angle.

If this is the case its not the end of the world to fix. Take out the old shocks clean out all the rusted areas and get a nice thick hunk of steel with a hole drilled in it welded in the original spot. That is what I had to do to my car. Probably best to do both sides at the same time because if one has rusted out the other cannot be too far behind.

If the shocks don't fix it, put back on the ground, get under it and compare the springs checking to see if one side has a collapsed coil(s).

Well ...

Low side :


High side :



I'm calling my mechanic when he'll be back to work to install new shocks!

Thanks for the replies guys !

Shocks don't hold the weight of the car, springs do (with the possible exception of new 'steins, which can have some upward pressure). If the car isn't level, it's much more likely the springs.

Pull the two rear shocks, or just disconnect the bottom and pull it free from the mount. See how it sits. I bet it's still off without the shock having any effect.
