Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and the engine is turned off.
Disconnect the battery to prevent any electrical issues during inspection.

2. Inspect Engine Mounts

Sub-steps:
- Locate the engine mounts (usually located at the front and rear of the engine).
- Visually inspect for cracks, tears, or separation in the rubber.
- Use a pry bar to check for excessive movement when pushing against the engine.
Tools Required: Pry bar, flashlight.

3. Check Power Steering Fluid

Sub-steps:
- Locate the power steering fluid reservoir.
- Check the fluid level and condition (should be clear and within the marked range).
- If low, top off with the manufacturer-recommended power steering fluid.
Tools Required: Funnel, power steering fluid.

4. Inspect Tires and Alignment

Sub-steps:
- Check tire pressure and inflate to the recommended PSI if necessary.
- Inspect tire tread for uneven wear.
- If uneven wear is found, consider rotating or replacing tires and performing a wheel alignment.
Tools Required: Tire pressure gauge, alignment tools (if necessary).
