Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the battery to prevent any electrical issues.

2. Check Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check the fluid level. If low, top up with the manufacturer's recommended fluid.
Inspect the fluid for contamination; if dirty, replace it.

3. Inspect Steering Components

Raise the front of the vehicle using a jack and secure it with jack stands.
Visually inspect the steering rack, tie rod ends, and ball joints for signs of wear or damage.
Use a pry bar to check for any excessive play in the tie rod ends and ball joints.

4. Replace Worn Components

If the steering rack is damaged, remove it by disconnecting the steering shaft, power steering lines, and mounting bolts.
Install the new steering rack following the manufacturer's torque specifications.
For tie rod ends or ball joints, remove the cotter pins and nuts, then use a tie rod puller to detach and replace them.

5. Reassemble and Refill

Reattach all components, ensuring they are properly torqued.
Refill the power steering fluid to the appropriate level.
Bleed the power steering system to remove any air by turning the steering wheel from lock to lock several times.
