Worn Shocks or Struts
Worn shocks or struts let the vehicle bounce, float, nose-dive, or vibrate over rough roads because the suspension is no longer controlling wheel movement.

Most Likely Causes
- 1
Internal damping wear
Oil and valving inside the shock/strut wear out over mileage.
- 2
Leaking shock or strut seal
Visible oil leakage means damping oil is escaping.
- 3
Damaged mount or bearing
A bad strut mount can add clunking, steering noise, or vibration.
- 4
Repeated heavy loads or rough roads
Frequent potholes, towing, and heavy cargo shorten shock life.
How to Diagnose It
- 1
Bounce and road behavior check
Excess bounce after dips, float at speed, or harsh oscillation over bumps points to weak damping.
Tool: Road test
- 2
Inspect for leaks and broken mounts
Look for oil trails, dented bodies, broken bushings, or torn mounts.
Tool: Flashlight
- 3
Check tire cupping
Worn dampers can cause scalloped tire wear from uncontrolled bouncing.
Tool: Flashlight, tread gauge
How to Fix It
Replace worn shocks/struts in pairs
Replace both sides of the axle to keep handling balanced.
Replace damaged mounts/bushings
Install new mounts or bushings if noise or play is present.
Align after strut replacement
Many strut repairs affect alignment and tire wear.
Mistakes to Avoid
- Do not replace only one front strut unless the other is nearly new and tests good.
- Do not ignore tire cupping; new tires may wear the same way.
- Do not remove loaded strut springs without proper tools.
