Solution

1. Tire Inspection and Maintenance

Check Tire Pressure: Use a tire pressure gauge to ensure all tires are inflated to the manufacturer’s recommended PSI.
Inspect Tires: Look for signs of uneven wear, bulges, or damage. Replace if necessary.
Balance Wheels: If tires are worn or damaged, have them balanced at a tire shop.

2. Wheel Alignment

Check Alignment: Use an alignment machine to assess wheel alignment settings.
Adjust Alignment: If the alignment is off, adjust it according to manufacturer specifications.

3. Drivetrain Inspection

Visual Inspection: Check motor mounts and axles for any visible signs of wear or damage.
Replace Components: If worn or damaged, replace motor mounts with OEM parts and ensure axles are intact.

4. Suspension Inspection

Visual Check: Inspect suspension components (struts, shocks, bushings) for damage or excessive wear.
Replace Worn Parts: If any components are found to be worn, replace them with high-quality parts.
