Symptoms & Diagnosis

Warning Signs of a Failing Front Strut Assembly:

  • Bumpy or bouncy ride
  • Excessive body roll when turning
  • Nose diving during braking
  • Uneven tire wear
  • Leaking fluid from the strut
  • Clunking or knocking noises when driving over bumps

How to Test if This Part is the Problem:

  1. Visual Inspection: Check the strut for any signs of damage, such as leaks, cracks, or dents.
  2. Bounce Test: Push down firmly on the front corner of the vehicle above the wheel. Release and observe how the vehicle bounces. It should rebound once and settle. Excessive bouncing indicates a worn strut.
  3. Road Test: Drive the vehicle over bumps and listen for unusual noises. Pay attention to how the vehicle handles during turns and braking.
  4. Compare Sides: Compare the feel and sound of the left (driver's side) strut to the right side. Significant differences can indicate a problem.

Common Failure Causes:

  • Normal wear and tear over time
  • Damage from potholes or road debris
  • Corrosion due to exposure to salt and moisture
  • Worn or damaged seals leading to fluid leaks
  • Impact damage from accidents

FAQ

Q: How do I know if I need to replace my front strut assembly?

A: Common signs include a bouncy ride, excessive body roll when turning, nose diving during braking, uneven tire wear, and clunking noises.

Q: Should I replace both front struts at the same time?

A: Yes, it's highly recommended to replace both front struts at the same time. This ensures even wear and tear and optimal handling.

Q: What is a strut spring compressor, and why do I need it?

A: A strut spring compressor is a tool used to safely compress the coil spring on the strut assembly. It's essential for safely disassembling and reassembling the strut. Without it, the spring can release with dangerous force.
