3. Inspect and Replace Steering Components

Inspect the power steering fluid:
- Remove the power steering reservoir cap and check fluid level.
- If low, top off with the manufacturer-recommended fluid.
Check steering components:
- Visually inspect tie rods and rack and pinion for wear.
- If damaged, remove the old components using a socket set and replace with new ones.
- Torque bolts to manufacturer specifications.

4. Inspect Suspension System

Check control arms and bushings:
- Look for cracks or excessive wear on bushings.
- Replace any damaged bushings by removing the control arm bolts and replacing with new ones.
Reinstall control arms and torque to specifications.

5. Inspect Wheel Bearings

Check for play:
- Grab the wheel at the 12 and 6 o’clock positions and wiggle to check for play.
- If play is detected, remove the wheel using a socket set.
- Inspect and replace the wheel bearings as necessary using appropriate tools.
