Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles.

2. Tire Pressure Adjustment

Tools Required: Tire pressure gauge, air compressor
Check and adjust tire pressure to the recommended levels indicated on the driver’s door jamb.

3. Wheel Alignment

Tools Required: Wheel alignment tools, jack, jack stands
Lift the vehicle using a jack and secure it with jack stands.
Adjust the alignment angles:
- Toe Angle: Adjust to manufacturer specifications, typically around 0 degrees.
- Camber Angle: Ensure camber is within allowable range, usually between -0.5 and +0.5 degrees.
- Caster Angle: Should be set according to specifications, generally between 3 and 5 degrees.
Tighten all adjustment bolts to the specified torque values.

4. Inspect and Replace Worn Components

Tools Required: Socket set, wrenches
Inspect tie rods, ball joints, and bushings for wear or damage.
Replace any worn components with OEM parts.
- Sub-steps:
  - Detach the old component using a socket set.
  - Install the new component, ensuring all fasteners are torqued to specifications.

5. Power Steering Fluid Check

Tools Required: Rags, funnel
Check the power steering fluid level in the reservoir.
If low, add the appropriate fluid type (usually ATF or specific power steering fluid).
Inspect for leaks if the fluid level is consistently low.
