Diagnostic Steps

1
Perform a bounce test: Press down on each corner of the vehicle and observe how many times it bounces before stabilizing.
2
Inspect the shocks and struts visually for any signs of leaks, damage, or corrosion.
3
Check tire pressure and examine tires for uneven wear patterns.
4
Drive the vehicle over bumps or rough terrain to listen for unusual noises.
5
Test the braking performance to see if the vehicle dives excessively when stopping.

Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, pry bar.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery if working with electronic components.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheels using a lug wrench to access the suspension components.

3. Remove Old Shocks or Struts

For shocks:
1. Locate the upper mount and lower bolt of the shock.
2. Use the socket set to remove the bolts, being careful not to damage surrounding components.
3. Pull the old shock out of its mount.
For struts:
1. Remove the upper strut mount bolts on the top of the strut tower.
2. Detach the lower bolts connecting the strut to the steering knuckle.
3. Carefully pull the strut assembly out from the vehicle.

4. Inspect and Clean

Inspect the mounting points and surrounding components for any signs of damage or wear.
Clean any dirt or debris from the mounting areas to ensure a proper seal.

5. Install New Shocks or Struts

For shocks:
1. Position the new shock in place and secure it with the upper and lower bolts.
2. Torque the bolts to the manufacturer’s specifications (refer to the service manual).
For struts:
1. Position the new strut assembly into the wheel well.
2. Secure the lower bolts first, then the upper strut mount bolts.
3. Torque all bolts to the manufacturer’s specifications.

6. Reassemble and Lower Vehicle

Reinstall the wheels and lower the vehicle back to the ground.
Tighten lug nuts to the specified torque.
