Important safety information - read before proceeding

•Always use jack stands when working under a vehicle.
•Allow the suspension components to settle and cool before handling.

Symptoms

•Excessive bouncing after hitting bumps
•Vehicle swaying or rolling during turns
•Uneven tire wear
•Difficulty controlling the vehicle on rough roads
•Fluid leakage from shock or strut assemblies
•Decreased ride comfort or noise during travel

Diagnostic Steps

1
Inspect the vehicle visually for any visible signs of damage or fluid leaks around the struts or shocks.
2
Perform a bounce test by pushing down on the front or rear of the vehicle and observing how many times it bounces before settling.
3
Check for uneven tire wear patterns that could indicate a suspension issue.
4
Drive the vehicle over bumps and listen for any unusual noises such as clunking or rattling.
5
Measure the ride height to check for sagging or unevenness between the front and rear of the vehicle.

Solution

Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and turn off the engine.
Wear safety glasses and gloves for protection.

2. Lift the Vehicle

Use a jack to lift the vehicle securely.
Place jack stands under the vehicle for safety.
Remove the wheels to access the struts or shocks.

3. Remove Old Struts or Shocks

For struts:
- Remove the top mounting bolts located in the engine compartment or trunk.
- Remove the lower mounting bolts at the bottom of the strut assembly.
- Carefully detach the strut from the vehicle.
For shocks:
- Remove the upper mounting bolt from the shock tower.
- Remove the lower mounting bolts from the axle or frame.
- Carefully pull the shock out of its mount.

4. Install New Struts or Shocks

For struts:
- Position the new strut assembly in place and secure it with lower mounting bolts.
- Reattach the top mounting bolts and ensure they are torqued to manufacturer specifications (typically around 30-50 ft-lbs).
For shocks:
- Insert the new shock into the mount and secure it with lower bolts.
- Attach the upper mounting bolt and torque it to specifications.

5. Reassemble and Lower Vehicle

Reattach the wheels and tighten the lug nuts in a crisscross pattern to the specified torque (usually around 75-85 ft-lbs).
Carefully lower the vehicle back to the ground.

6. Final Checks

Inspect all components for proper installation.
Test the vehicle for any abnormalities during a short drive.
