1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely lifted using a jack and jack stands.
Disconnect the battery to prevent any electrical issues during repairs.

2. Inspect and Replace Steering Components

Steering Rack Inspection
- Remove the underbody cover if applicable.

- Use a socket set to remove the tie rod end nut.
- Use a tie rod puller to disconnect the tie rod from the steering knuckle.
- Install the new tie rod end by reversing the removal process. Torque to manufacturer specifications (typically around 35-45 ft-lbs).
Ball Joint Inspection and Replacement
- Inspect the ball joints for wear by checking for excessive play.
- If replacement is needed, remove the nut securing the ball joint to the control arm, then use a ball joint separator to detach it.
- Install the new ball joint and secure it with the nut, torquing it to manufacturer specifications.

3. Power Steering Fluid Check

Locate the power steering reservoir and check the fluid level.
If low, top off with the appropriate fluid specified in the owner's manual.
Inspect for leaks in the power steering lines and connections.

4. Alignment Check

After replacing any components, take the vehicle to a professional alignment shop to ensure proper steering geometry.
