Solution

1. Preparation

Tools Needed: OBD-II scanner, tire pressure gauge, jack and jack stands, torque wrench, basic hand tools (socket set, wrenches).
Safety Warnings: Ensure the vehicle is parked on a flat surface, engage the parking brake, and wear safety glasses.

2. Address Tire Issues

Sub-steps:
1. Check tire pressure using a tire pressure gauge and inflate to the recommended PSI.
2. Rotate tires if uneven wear is detected to promote even wear.
3. Replace any damaged or excessively worn tires.

3. Align Wheels

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Ensure that the alignment specifications match manufacturer recommendations.

4. Replace Worn Suspension Components

Sub-steps:
1. Identify any worn suspension components during inspection.
2. Remove the damaged part by loosening bolts (use torque specifications from the service manual).
3. Install the new suspension component, tightening to the specified torque.

5. Inspect and Replace Brake Components

Sub-steps:
1. Remove the wheel to access the brake assembly.
2. Check the brake pads for thickness; replace if worn below recommended levels.
3. Inspect the rotors for warping; resurface or replace if necessary.
4. Reassemble the brake system and torque all components to specifications.
