Symptoms & Diagnosis

Warning Signs of a Failing Suspension Strut:

  • Bouncy ride: Your vehicle bounces excessively after hitting bumps.
  • Leaking fluid: Oil or other fluid is visible on the strut body.
  • Clunking noises: You hear a clunking or knocking sound, especially when going over bumps.
  • Uneven tire wear: Your tires are wearing unevenly, often on the inside or outside edge.
  • Poor handling: Your vehicle feels unstable or difficult to control, especially when cornering.
  • Nose diving: The front of your vehicle dips excessively when braking.

How to Test if the Strut is the Problem:

  1. Bounce Test: Push down firmly on the corner of the vehicle above the strut. Release quickly. The vehicle should rebound once and then settle. Excessive bouncing indicates a worn strut.
  2. Visual Inspection: Carefully inspect the strut for leaks, damage, or corrosion.
  3. Road Test: Drive the vehicle over bumps and listen for unusual noises. Pay attention to how the vehicle handles.
  4. Compare Sides: If possible, compare the feel and sound of the suspension on the side with the suspected bad strut to the other side.

Common Failure Causes:

  • Normal wear and tear: Over time, the strut's internal components wear out.
  • Road conditions: Driving on rough roads or hitting potholes can damage the strut.
  • Corrosion: Exposure to salt and moisture can cause the strut to corrode.
  • Damaged seals: Seals can dry out and crack, leading to fluid leaks.
  • Impact damage: Accidents or hitting large objects can damage the strut.

Buyer's Checklist

What to Look For When Buying:

  • Compatibility: Ensure the strut is specifically designed for your 2020-2025 Buick Encore GX (Right/Passenger side).
  • Condition: Choose the condition that best fits your budget and needs (Used OEM, Refurbished OEM, New Aftermarket).
  • Warranty: Look for a warranty that covers defects in materials or workmanship.
  • Reputation: Research the reputation of the seller or manufacturer.

Critical Steps and Tips:

  1. Safety First: Always use jack stands to support the vehicle. Never work under a vehicle supported only by a jack.

  3. Disconnect Components: Disconnect any brake lines, ABS sensors, or other components attached to the strut assembly.
  4. Remove Old Strut: Unbolt the old strut from the vehicle.
  5. Install New Strut: Install the new strut, ensuring all bolts are properly torqued to the manufacturer's specifications.
  6. Reconnect Components: Reconnect any brake lines, ABS sensors, or other components.
  7. Release Spring Compressor: Carefully release the spring compressor.
  8. Wheel Alignment: It is highly recommended to get a wheel alignment after replacing struts.

FAQ

Q: How do I know if I need to replace just one strut or both?
A: It's generally recommended to replace struts in pairs (both front or both rear) to ensure balanced handling and braking. Replacing just one strut can cause uneven wear and tear on other suspension components.

Q: Can I replace the strut myself, or do I need to take it to a mechanic?
A: Replacing struts can be a DIY project for experienced mechanics with the proper tools and safety precautions. However, it involves compressing coil springs, which can be dangerous. If you're not comfortable working on suspension systems, it's best to have a professional install the struts.

Q: What is the difference between a strut and a shock absorber?
A: While both struts and shock absorbers control movement, a strut is a structural part of the suspension system, providing support for the vehicle's weight. A shock absorber only dampens movement.

Q: How often should I have my suspension checked?
A: It's a good idea to have your suspension checked at least once a year, or more often if you drive on rough roads or notice any signs of suspension problems.

Q: Will replacing my struts improve my car's handling?
A: Yes, replacing worn struts can significantly improve your car's handling, ride quality, and braking performance. New struts will provide better control and stability, especially when cornering or braking.
