HERE IS THE DEAL Posted by saabsince 93b [Email] (#972) [Profile/Gallery] (more from saabsince 93b) on Wed, 30 May 2012 16:05:51 In Reply to: Re: Rear suspension, ride height and aligment, jeff02 [Profile/Gallery] , Wed, 30 May 2012 14:58:33 Members do not see ads below this line. - Help Keep This Site Online - Signup |
The wear is caused by toe-in. Front of the rear tires pointing in. You need a little, but too much really wears your tires.
How come you got too much toe-in? When the suspension lowers with sagging springs.....ride height is low, the camber increases and the toe-in increases. the suspension is designed that way for cornering.
You need to get your ride height to 610 mm from the bottom of the rear wheel opening to the lower edge of the rim. Check it right now and see what you need.
I would not replace the springs. The old ones are fine with some spacers to make up for the sag. I would buy yellow Konis from genuinesaab dot you know what. for 208.32 per pair. Set the spring perch on the upper setting and put one of their 15mm spacers on each side. These cost $12.00 each and are really trick. Measure the ride height and have the car aligned front and rear. Get a WIS for all suspension measurements.
I have a 2001 Aero and did all of the above to solve the same problem.
Also recommended is replacing the lower outer lateral arm bushes with OEM rubber bushes. Also the front of the trailing arm could be fitted with a poly bushing.
