Unless all those corpses in my trunk are weighing it down :) A common look of many classic 900s.

It is an easy job to do if you have been doing other work on cars. When I did this on a 1983 900 I needed two of everything. 2 hydraulic jacks and two pairs of spring clamps/compressors. You also need stands which you could use to support the car with (not the axle). From memory you have to remove the bottom bolt of the shock absorber and then remove the bolt of the trailing arm. > > On a related note, I noticed that the front tire on the left side seems to be > wearing on the outside edge, whereas the right front tire isn't as much. Could > this maybe be a ball joint issue? Are you in a left hand or right hand drive country? The left tyre is more likely to do what you say on a left hand drive country. How many miles has the car done? Yes it can be a ball joint ... it can also be: - a steering knuckle joint (the ball joint at the end of the steering rod); - simply incorrect toe alignment (could happen with use and occasional meets with curbs etc); - other much more expensive things. Basically the wheel is having to turn slightly to the right in order to keep the car going in a straight line. On a left hand drive country the camber of the road + wear and tear on the ball joints (all 3 of them on each side) is enough to produce the results you see. I would look for a bad ball joint and replace. It can be on either side of the car. It can be more than one joint. > > I don't know a whole lot about the suspension, and would appreciate any > enlightenment. Hope it helps a little.
