⚠️ Safety Warnings

Important safety information - read before proceeding

•Always ensure the vehicle is securely supported by jack stands before working underneath it.
•Disconnect the battery before working on any electrical components.

Symptoms

•Excessive bouncing after hitting bumps
•Vehicle swaying or rolling during turns
•Uneven tire wear
•Increased stopping distance
•Fluid leakage from the strut assembly
•Noise when driving over bumps (clunking or rattling sound)

Diagnostic Steps

1
Visually inspect the struts for any signs of fluid leakage or physical damage.
2
Perform a bounce test: push down on the front or rear of the vehicle and observe how many times it bounces before settling.
3
Check the alignment of the vehicle to see if it is pulling to one side, which could indicate strut issues.
4
Inspect tires for uneven wear patterns, which may suggest problems with the struts.
5
Listen for any abnormal noises while driving over bumps or rough terrain.
6
Perform a road test to assess handling and stability during turns and braking.

Solution

Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Use wheel chocks to secure the vehicle.
Disconnect the negative battery terminal to ensure safety.

2. Raise the Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle as needed.
Secure the vehicle on jack stands for safety.

3. Remove the Wheel

Using a socket set, loosen and remove the lug nuts.
Take off the wheel to gain access to the strut assembly.

4. Remove the Strut Assembly

Locate the strut mounting bolts on the top and bottom of the strut.
Use a socket set to remove the top strut mount bolts from the engine bay.
Remove the lower strut bolts connecting it to the steering knuckle.
Carefully extract the strut from the vehicle.

5. Install New Strut

Position the new strut assembly in place.
Reinstall the lower bolts and torque them to the manufacturer's specifications (typically around 50-70 ft-lbs).
Reattach the top strut mount bolts and torque them to the required specification.

6. Reassemble

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and onto the ground.
Tighten the lug nuts to the specified torque (usually around 80-100 ft-lbs).

7. Final Checks

Reconnect the negative battery terminal.
Test drive the vehicle to ensure proper handling and comfort.
