Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear safety goggles and gloves during the repair process.

2. Inspect and Replace Suspension Components

Inspect:
- Check for worn-out bushings, control arms, and ball joints.
- Look for leaks in shock absorbers or struts.
Replace (if necessary):
- Remove the wheel to access suspension components.
- Use a socket set to remove bolts securing the strut or shocks.
- Install new components, ensuring all bolts are torqued to manufacturer specifications (typically around 50-80 ft-lbs for suspension bolts).

3. Wheel Alignment

Alignment Process:
- After replacing any suspension parts, take the vehicle to a professional alignment shop.
- Ensure that the camber, caster, and toe are adjusted to meet manufacturer specifications.

4. Tire Inspection and Replacement

Inspect Tires:
- Check for uneven wear and tread depth.
- If tires show signs of excessive wear or damage, replace them.
Balancing:
- Ensure that all tires are balanced properly when installed.
