Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Disconnect the battery to prevent any electrical shorts during inspection.

2. Tire Pressure Adjustment

Using a tire pressure gauge, check the pressure in all four tires.
Inflate or deflate tires to the manufacturer’s recommended PSI, which can be found on the driver’s door jamb.
Recheck pressure after adjustment.

3. Tire Inspection and Replacement (if necessary)

Remove each tire using a socket set.
Inspect the tread depth with a tread gauge; replace tires if tread is below 2/32 of an inch or shows uneven wear.
If replacement is needed, install new tires and ensure they are balanced properly.

4. Steering Fluid Check and Replacement

Locate the steering fluid reservoir and check fluid level.
If low, top off with manufacturer-recommended steering fluid.
If fluid is discolored or contaminated, drain and replace with fresh fluid:
- Disconnect the return line to the pump and drain into a container.
- Reconnect the line and fill the reservoir with new fluid.

5. Steering Alignment Adjustment

Take the vehicle to a professional alignment shop.
Ensure that the alignment is adjusted to the manufacturer’s specifications.

6. Steering Component Inspection

Visually inspect the steering rack, tie rods, and other components for wear.
Replace any worn components using manufacturer-specified parts.
