Solution

1. Preparation

Gather tools and parts needed.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety goggles and gloves.

2. Inspect and Replace Worn Suspension Components

Sub-steps:
1. Lift the vehicle using a hydraulic jack and secure it with jack stands.
2. Remove the front wheels using a socket set.
3. Inspect the shocks and struts for leaks or signs of wear.
4. If any components are worn, remove them by unbolting from the chassis and lower control arm.
5. Install new shocks or struts, ensuring they are torqued to manufacturer specifications (typically around 30-50 Nm).

3. Wheel Alignment

Sub-steps:
1. After replacing any suspension components, reinstall the front wheels.
2. Lower the vehicle and roll it forward a few feet to settle the suspension.
3. Use a laser alignment tool to check the wheel alignment.
4. Adjust the toe, camber, and caster settings to align with manufacturer specifications.

4. Tire Inspection and Replacement

Sub-steps:
1. Inspect tires for bulges, cracks, or uneven wear.
2. If tires are damaged, remove them and replace with new tires of the same specification.
3. Balance the tires using a tire balancer to ensure a smooth ride.
4. Reinstall the front wheels and torque to manufacturer specifications (typically around 120-140 Nm).
