3-5 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always use jack stands when working under the vehicle.
•Allow the struts to cool if they have been recently in use to avoid burns.

Symptoms

•Excessive bouncing or swaying during driving
•Uneven tire wear
•Vehicle feels unstable or floats at high speeds
•Visible oil leakage from the strut assembly
•Difficulty in maintaining control during turns
•Noise such as clunking or rattling over bumps

Diagnostic Steps

1
Inspect the struts visually for any signs of oil leakage or damage.
2
Perform a bounce test by pressing down on the front or rear of the vehicle and observing how it rebounds.
3
Check tire wear patterns for uneven wear, which can indicate strut issues.
4
Test drive the vehicle to notice any abnormal handling, swaying, or noise.
5
Measure the ride height of the vehicle to check for sagging.

Solution

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and set the parking brake.

2. Lift the Vehicle

Use a jack to lift the vehicle and place jack stands under the frame for safety.
Remove the wheels to access the struts.

3. Remove Old Struts

Tools Required: Socket set, torque wrench, strut spring compressor.
Loosen and remove the bolts securing the strut to the steering knuckle.
Detach any connections to the sway bar link and brake line from the strut.
Remove the top strut mounting nuts from the engine bay.
Carefully extract the strut assembly from the vehicle.

4. Inspect and Replace Components

Inspect strut mounts and bearings for wear; replace if necessary.
Use a strut spring compressor to safely compress and remove the coil spring from the old strut.
Install the coil spring onto the new strut following manufacturer specifications.
Ensure all components are properly aligned and tightened to torque specifications.

5. Reinstall New Struts

Insert the new strut assembly into the vehicle.
Reattach the top strut mounting nuts and torque to specifications.
Reconnect the sway bar link and brake line to the strut.
Secure the strut to the steering knuckle with bolts and torque accordingly.

6. Lower Vehicle and Test

Remove jack stands and lower the vehicle.
Reinstall the wheels and torque the lug nuts to specifications.
Perform a test drive to verify improved handling and ride quality.
