How do you adjust the rear wheel alignment on 1998 cavalier?

You can't adjust the rear wheel alignment on a 1998 Chevrolet Cavalier (or most modern cars with a rear torsion beam axle). The rear suspension doesn't have the camber or toe adjustment mechanisms found on independent rear suspensions. The rear alignment is fixed by the design of the axle and suspension components.

If you suspect a problem with the rear wheel alignment, the issue likely stems from:

* Bent or damaged components: A bent axle, control arm, or other suspension part from an impact would affect the alignment and require replacement, not adjustment.

* Worn suspension parts: Worn bushings or other suspension components can lead to changes in the rear wheel's position, although this would usually manifest as more of a handling problem than a precise alignment issue.

What to do if you suspect a rear wheel alignment problem:

1. Check for obvious damage: Carefully inspect the rear suspension for any bent or broken parts.

2. Have a professional inspection: Take your Cavalier to a qualified mechanic or tire shop. They can properly diagnose the issue and determine if there's a problem beyond simply needing an alignment (which is not adjustable in the rear). They have the equipment to accurately measure the wheel alignment and identify the source of any issues.

Trying to "adjust" the rear alignment yourself on a torsion beam axle is likely to be futile and could potentially damage the suspension. Focus on professional diagnosis and repair if you're experiencing problems.
