Suspension

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always use jack stands when working under the vehicle.
•Allow the vehicle to cool down before working on suspension components.

Symptoms

•Excessive bouncing after hitting bumps
•Vehicle swaying during turns
•Uneven tire wear

1. Preparation

Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Gather necessary tools and parts.

2. Lift the Vehicle

Using a hydraulic jack, lift the front or rear of the vehicle as needed.
Secure the vehicle with jack stands to ensure safety.

3. Remove the Strut Assembly

Tools Required: Socket set, wrench set, torque wrench
Remove the wheel to access the strut assembly.
Disconnect the sway bar link from the strut using a socket.
Remove the lower strut mounting bolts and nuts.
Unbolt the strut from the upper mount in the engine bay (may require removing the hood insulation).
Carefully slide the strut assembly out of the vehicle.

4. Inspect and Replace

Inspect the strut for signs of wear, leakage, or damage.
If replacement is necessary, install the new strut by reversing the removal process.
Torque specifications: Follow manufacturer guidelines for torque values on strut bolts.

5. Reassemble and Lower the Vehicle

Reattach the wheel and tighten the lug nuts to the specified torque.
Carefully lower the vehicle from the jack stands and remove the hydraulic jack.
