Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to ensure safety during repairs.

2. Inspect and Adjust Tires

Sub-steps:
- Use a tire pressure gauge to check all tires; adjust to the manufacturer's recommended pressure.
- Visually inspect tires for uneven wear or damage; replace if necessary.

3. Brake System Inspection

Sub-steps:
- Remove the wheel to access the brake components.
- Check brake calipers; ensure they move freely and are not binding. Clean or replace if necessary.
- Inspect brake pads for uneven wear; replace if worn down to below specification.

4. Transmission Fluid Check

Sub-steps:
- Remove the transmission dipstick or fill plug to check fluid level.
- If low, add the appropriate type of transmission fluid as specified in the owner's manual.
- If the fluid is dark or has a burnt smell, consider a transmission fluid change.

5. Suspension Component Inspection

Sub-steps:
- Visually inspect suspension bushings and joints for cracks or wear.
- Check for any signs of binding or excessive play in suspension components.
- Replace any worn parts as necessary.
