Most Likely Causes

  1. 1

    Toe out of spec

    Toe wear causes feathering and rapid tread wear.

  2. 2

    Camber out of spec

    Camber can wear one shoulder of the tire.

  3. 3

    Caster imbalance

    Caster differences can cause pull.

  4. 4

    Bent or worn suspension part

    Alignment may not hold if parts are loose or bent.

How to Diagnose It

  1. 1

    Inspect tire wear pattern

    Feathering, edge wear, or cupping gives alignment clues.

    Tool: Tread gauge

  2. 2

    Check steering wheel center

    Off-center wheel after straight driving points to alignment or pull.

    Tool: Road test

  3. 3

    Perform alignment measurement

    Use alignment rack to measure toe/camber/caster.

    Tool: Alignment rack

How to Fix It

  • Repair loose parts first

    Alignment cannot be set correctly with worn joints or bushings.

  • Perform four-wheel alignment

    Set angles to specification.

  • Replace damaged tires if wear is severe

    Badly worn tires may continue to pull or vibrate.

Alignment Out of Spec

Wheel alignment out of spec means camber, caster, or toe angles are wrong, causing pulling, uneven tire wear, off-center steering, or unstable handling.

Fix SoonDIY EasyMost likely: Pothole or curb impact

Bad Ball Joint

Bad Ball Joint can cause clunks, pulling, bouncing, vibration, or unstable handling. Confirm the failed joint, bushing, shock, tire, or alignment problem before replacing suspension parts.

Fix SoonDIY ModerateMost likely: Worn joint or bushing with excessive play

Bad Ball Joint Symptoms

Bad ball joint symptoms include a clunking noise from the front suspension over bumps, loose or wandering steering, and one-sided edge tire wear. Ball joints are critical safety components — a completely failed ball joint can fold the wheel under the car at highway speed without warning.

Fix SoonDIY EasyMost likely: Normal wear over time

Bad CV Axle Joint

Bad CV Axle Joint can cause clunks, pulling, bouncing, vibration, or unstable handling. Confirm the failed joint, bushing, shock, tire, or alignment problem before replacing suspension parts.

Fix SoonDIY ModerateMost likely: Worn joint or bushing with excessive play

Bad Tie Rod End

Bad Tie Rod End can cause clunks, pulling, bouncing, vibration, or unstable handling. Confirm the failed joint, bushing, shock, tire, or alignment problem before replacing suspension parts.

Fix SoonDIY ModerateMost likely: Worn joint or bushing with excessive play

Bad Tie Rod Symptoms

Bad tie rod symptoms include a shaky steering wheel, car pulling to one side, uneven tire wear, and a clunking or knocking sound when turning or hitting bumps. Tie rods connect the steering rack to the front wheels — worn ends allow the wheel to move independently of the steering input.

Fix SoonDIY ModerateMost likely: Worn outer tie rod end

Mistakes to Avoid

  • Do not align a vehicle with loose ball joints, tie rods, or control arm bushings.
  • Do not ignore tire pressure before diagnosing alignment pull.
  • Do not expect alignment to fix a separated tire.
