Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and ensure it is in 'Park' or gear.
Disconnect the battery for safety.

2. Inspect and Replace Tie Rod Ends

Sub-steps:
1. Lift the front of the vehicle using a jack and secure it with jack stands.
2. Remove the front wheels using a socket set.
3. Locate the tie rod ends and check for any visible wear or play.
4. If replacement is needed, use a tie rod end puller to separate the tie rod end from the steering knuckle.
5. Install the new tie rod end and torque it to manufacturer's specifications (typically around 50-60 ft-lbs).
6. Reinstall the wheel and lower the vehicle.

3. Check and Replenish Power Steering Fluid

Sub-steps:
1. Locate the power steering fluid reservoir.
2. Remove the cap and check the fluid level against the dipstick.
3. If low, add the recommended type of power steering fluid (often ATF or specific PS fluid) as per the owner's manual.

4. Inspect and Replace Steering Rack (if necessary)

Sub-steps:
1. If loose steering persists, inspect the steering rack for wear.
2. Disconnect the steering shaft from the rack.
3. Remove the mounting bolts securing the steering rack and disconnect the power steering lines.
4. Install the new steering rack and torque the bolts to specifications.
5. Reconnect the steering shaft and lines, and check for leaks.
