Solution

1. Preparation

Gather necessary tools and ensure the vehicle is parked on a flat surface.
Ensure you have safety equipment (gloves, goggles).
Disconnect the battery if working on electrical components.

2. Tire Inspection and Replacement

Sub-steps:
1. Check tire pressure with a tire gauge; inflate to manufacturer specifications if low.
2. Inspect tires for uneven wear; replace if necessary.
Tools Required: Tire pressure gauge, tire iron.

3. Shock Absorber/Strut Replacement

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the suspension components.
3. Unbolt the shock/strut assembly from the top and bottom mounts.
4. Install the new shock/strut in reverse order, tightening to manufacturer torque specifications (usually around 30-50 Nm for mounts).
Tools Required: Socket set, torque wrench, jack and jack stands.

4. Control Arm and Bushing Replacement (if necessary)

Sub-steps:
1. Inspect the control arms and bushings for cracks or excessive wear.
2. Remove the control arm bolts and detach the arm from the vehicle.
3. Replace bushings if worn, install the new control arm, and torque bolts to manufacturer specifications (typically 60-80 Nm).
Tools Required: Socket set, bushing removal tool, torque wrench.

5. Wheel Alignment

Sub-steps:
1. After replacing components, take the vehicle to an alignment shop.
2. Ensure all alignment angles (camber, caster, toe) are adjusted to manufacturer specifications.
Tools Required: Alignment machine (performed by a professional).
