⚠️ Safety Warnings

Important safety information - read before proceeding

•Always ensure the vehicle is securely supported on jack stands before working underneath.
•Use caution when handling compressed springs, as they can be dangerous if released improperly.

Symptoms

•Excessive bouncing after hitting bumps
•Uneven tire wear
•Vehicle swaying or leaning during turns
•Difficulty maintaining control on rough roads
•Noises such as clunking or knocking when driving over bumps
•A noticeable drop in ride comfort

Diagnostic Steps

1
Visual Inspection: Examine the struts for any visible signs of damage, such as leaks or rust.
2
Bounce Test: Push down firmly on each corner of the vehicle and release. The car should rebound once; if it continues to bounce, the struts may be worn.
3
Check for Fluid Leaks: Inspect for any oily residue around the strut body, indicating a leak in the strut seal.
4
Tire Inspection: Check the tires for uneven wear patterns, which can indicate strut issues.
5
Road Test: Drive the vehicle over bumps and listen for abnormal noises; pay attention to how the vehicle handles during turns.
6
Professional Assessment: If unsure, consider having a qualified technician perform a more thorough evaluation.

Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, strut spring compressor, and safety glasses.
Safety Warning: Always ensure the vehicle is securely supported on jack stands before working underneath.

2. Remove Struts

Lift the Vehicle: Use the jack to lift the front or rear of the vehicle. Secure with jack stands.
Remove Wheel: Use a socket set to remove the lug nuts and take off the wheel.
Disconnect Strut Assembly:
- Remove any brake line clips or sensors attached to the strut.
- Unbolt the strut from the lower control arm and top mount (usually located in the engine bay).
Use Spring Compressor: Carefully compress the spring using a spring compressor to relieve tension before removing the strut from the assembly.

3. Inspect and Replace

Inspect Strut Components: Check the strut for any signs of damage or leaks.
Replace Strut: If the strut is bad, replace it with a new or remanufactured strut, ensuring proper orientation and alignment.
Reassemble:
- Reinstall the top mount and lower control arm bolts. Torque to manufacturer specifications.
- Reconnect any disconnected brake lines or sensors.

4. Reinstallation

Reattach Wheel: Place the wheel back on and hand-tighten the lug nuts.
Lower Vehicle: Carefully lower the vehicle to the ground and torque the lug nuts to the recommended specification.
