Hi,
I recently purchased a 2001 Aero. The rear end seems to have a lot of negative camber. I took it to a local alignment shop and they said that it was reading 2.4 degrees negative and it could not be adjusted. The tires are wearing very much on the inside. I am sure this is not normal as it seems I will be going through tires in no time. How can I fix this?
Also the steering sometimes pulls to the left or right fairly hard. It is not consistently pulling to one side or the other. I replaced the tie rod ends and had an alignment done and it seems better but not 100%. Other than those things the car is amazing. Thanks in advance for the help.

Pete, is the car standard or has it been lowered with aftermarket shocks and springs? Some people with aftermarket kit, have had to have shims made up for the rear, to stop excessive camber and the insides of their tyres wearing prematurely.:roll:

As far as I know the suspension is stock. But the tires are wearing excessively on the inside. Could it just be worn springs/shocks? The car has 60k milies on it.

Hi Pete welcome to Saab Central. Do you have a warantee, if so why not pop back to the dealer and ask them. You shouldnt be getting the wear like you suggest. As far as shocks and springs being worn it is possible, particularly If the last owner consistantly carried heavy weight in the boot. :confused:

Thanks. Unfortunately there was only a 30 day warranty, which is now up. As I was driving to work today I had athought about the steering pulling as mentioned in my first post. Could it be that I rotated my tires, putting the ones that were worn on the inside from the rear to the front, that would cause that?

Pete, there is always debate about rotating tyres. Personally there is no way I would rotate my tyres. If you do have a problem with the camber on the rear then all you are doing is wearing out another set of tyres and putting problem tyres on the front :eek: If they are worn then replace them. :confused: You are in a front wheel drive car and the contact patch on the road is very important. Particularly so in the aero where you you get high torque, the weight of the car under braking is all on the front tyres this also includes cornering, I would hate for them to break away from you on a sharp corner because they are worn on the inner edge. I would highly recommend that perhaps you pop along to a specialist who can check your shocks, spring and tyres.

I would agree with suspension wear and shocks have been known to go at this mileage too :cry: If you rotate tyres you'll end up needing 4 surely?:confused:

I had to rotate the tires because they were almost bald on the inside. I have new tires but I want to correct this problem before I put them on. Thank you all for your help. I will be taking my car to the dealer to see what is going on.

By the book, for the ride height, the camber on my 2000 Aero Estate is spot on specification (from memory it is 2.5deg negative). The suspension is standard with no suspension play evident. It does sit a little lower than the "book" says is standard and the way the suspension is designed you increase the negative camber as the ride lowers.

Even with this much negative camber I have found that the tyres wear quite well.

The rear suspension on 9-5 IS adjustable, but you will need to get a Saab specialist to do it and I would bet it would be pricey.

"Standard" height will vary depending on the specific market and the spring set used. The way to measure the height is to measure from the bottom of the lip on the mudguard to the bottom of the rim (lower obviously). Once you have this measurement, a Saab specialist will be abel to tell you what camber you should have.
