Solution

1. Preparation

Gather all necessary tools and parts before starting the repair.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery for safety during electrical component inspections.

2. Inspect and Replace Power Steering Fluid

Tools Required: Fluid extraction tool, funnel.
Remove the power steering reservoir cap and check the fluid level.
If low, use a fluid extraction tool to remove old fluid and replace it with manufacturer-recommended power steering fluid.
Reattach the reservoir cap securely.

3. Replace Worn Steering Components

Tools Required: Socket set, torque wrench, pry bar, jack stands.
Lift the front of the vehicle and secure it with jack stands.
Remove the wheel to access the steering components.
Inspect and replace any worn-out tie rods, control arms, or bushings.
- Sub-steps:
  1. Use a socket set to remove the bolts securing the components.
  2. Use a pry bar if needed to detach the old parts.
  3. Install new parts, ensuring they are torqued to manufacturer specifications.

4. Check and Adjust Wheel Bearings

Tools Required: Bearing puller, torque wrench.
Spin the wheel to check for noise or roughness.
If noise is present, remove the wheel and inspect the wheel bearings.
- Sub-steps:
  1. Remove the hub assembly if necessary.
  2. Replace the bearings if they are worn or damaged.
  3. Reassemble and torque the hub nut to manufacturer specifications.

5. Inspect and Replace Brake Components

Tools Required: Brake caliper tool, socket set, torque wrench.
Check the brake pads for wear; replace if necessary.
- Sub-steps:
  1. Remove the caliper using a socket set.
  2. Inspect the rotors for scoring; replace if damaged.
  3. Install new pads and caliper, torquing bolts to specification.
