Solution

1. Preparation

Gather tools: socket set, multimeter, torque wrench, and safety goggles.
Disconnect the negative terminal of the battery to prevent electrical shock.

2. Remove Starter Motor

Locate the starter motor (usually near the transmission).
Disconnect the electrical connections from the starter (note their placement).
Remove the mounting bolts using a socket set.
Carefully pull the starter motor out of its position.

3. Inspect and Repair

Inspect Starter: Check for worn brushes, damaged gears, or burnt contacts. Replace any faulty components or the entire starter if necessary.
Check Flywheel: Inspect the flywheel for damaged or missing teeth. If damaged, the flywheel must be replaced.

4. Reinstall Starter Motor

Position the starter motor back into place.
Reinstall the mounting bolts and torque them to the manufacturer's specifications (typically around 25-30 ft-lbs).
Reconnect the electrical connections.

5. Reconnect Battery and Test

Reconnect the negative terminal of the battery.
Start the engine to check for the grinding noise.
