Solution

1. Preparation

Gather necessary tools and parts for the repair.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Belts

Tools Required: Socket set, belt tensioner tool.
Remove the engine cover if applicable.
Inspect the serpentine belt for signs of wear. If damaged, remove the belt by releasing tension with the belt tensioner tool.
Replace with a new serpentine belt, ensuring proper alignment and tension according to manufacturer's specifications.

3. Inspect and Adjust Tire Alignment

Tools Required: Tire pressure gauge, alignment tools.
Check tire pressure and adjust to manufacturer specifications if necessary.
Inspect the wheel wells for any signs of rubbing against the tires. If found, adjust or replace affected components to prevent contact.

4. Brake System Evaluation

Tools Required: Jack and jack stands, brake cleaner.
Lift the vehicle and remove the wheel to access the brake components.
Inspect brake calipers for proper function; check for any signs of sticking or overheating.
If calipers are found to be seized, replace them with new ones. Clean the rotor surfaces with brake cleaner and reassemble.

5. Final Checks

Reconnect the battery and start the vehicle.
Allow the engine to reach operating temperature while monitoring for any unusual smells or noises.
