Which diagnostic check detects a rear axle misalignment?

Rear axle alignment is controlled by the tracking bar, which fixes the axle’s lateral position relative to the vehicle frame. A tracking bar check specifically evaluates this linkage—its length, mounting points, and bushings—for wear, damage, or improper adjustment. If the bar is worn or misadjusted, the rear axle can sit off-center, indicating misalignment. Wheel alignment looks at wheel angles and steering geometry, not the rear axle’s lateral position. Visual inspection may spot obvious damage but isn’t a precise test of axle alignment, and a brake test doesn’t assess axle alignment at all.
