Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the 12V battery to prevent electrical issues while working on the suspension.

2. Inspect Suspension Components

Remove the front and rear wheels using a socket set.
Inspect struts and shocks for leaks or physical damage.
Check control arms, tie rods, and sway bar links for wear or play.

3. Replace Worn Components

Front Suspension

Remove the strut assembly:
- Use a spring compressor to safely compress the coil spring.
- Remove the bolts securing the strut to the steering knuckle.
- Unbolt the strut from the upper mount and remove it.
Replace strut or bushing:
- Install the new strut or bushing as required.
- Reassemble the strut mount with the specified torque value (check service manual for exact specifications).

Rear Suspension

Remove rear shock absorbers:
- Unbolt the lower and upper shock mount bolts.
- Remove the shock absorber from the vehicle.
Install new shock absorber:
- Position the new shock in place and tighten bolts to the manufacturer’s torque specifications.

4. Reassemble Suspension

Reinstall wheels and lower the vehicle.
Torque wheel lug nuts to the specified value.
