Important safety information - read before proceeding

•Always use jack stands when working underneath a vehicle.
•Ensure the vehicle is on a flat, stable surface before lifting.

Symptoms

•Fluid leakage around the struts
•Excessive bouncing or instability while driving
•Unusual noises over bumps (clunking or knocking)
•Uneven tire wear

Diagnostic Steps

1
Inspect the struts visually for signs of oil leakage.
2
Check for any physical damage to the strut assembly or mounting points.
3
Perform a bounce test by pushing down on the front or rear of the car and observing how quickly it returns to rest.
4
Examine the surrounding components for signs of wear or damage that may contribute to strut failure.
5
Verify alignment settings as improper alignment can accelerate strut wear.

Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the negative battery terminal to prevent electrical issues.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheels to access the struts.

3. Remove Old Struts

Front Struts:
1. Remove the bolts securing the strut to the steering knuckle.
2. Disconnect the brake line and any sensors attached to the strut.
3. Remove the top strut mount bolts located in the engine bay (may require a ratchet and socket).
4. Carefully pull the strut assembly out of the wheel well.
Rear Struts:
1. Remove the nuts from the top of the strut in the trunk.
2. Disconnect any electrical connectors and brake lines.
3. Remove the lower mounting bolts at the bottom of the strut.
4. Take the strut assembly out of its position.

4. Install New Struts

Place the new strut assembly into the vehicle, aligning it with the mounting points.
Secure the lower strut bolts and torque them to the manufacturer specifications (typically around 50 lb-ft).
Reattach the brake line and any electrical connectors.
Install the top strut mount bolts, ensuring they are properly torqued (usually around 30 lb-ft for the front, 16 lb-ft for the rear).

5. Reassemble the Vehicle

Reinstall the wheels and lower the vehicle back to the ground.
Torque the wheel lug nuts to the proper specifications (typically 76 lb-ft).
