Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent any electrical issues.

2. Inspect and Replace Power Steering Fluid

Sub-steps:
- Locate the power steering reservoir and remove the cap.
- Check the fluid level; if low, top off with manufacturer-recommended fluid.
- If fluid is dark or contaminated, drain the old fluid by locating the return line and disconnecting it.
- Refill with new power steering fluid and check for leaks.

3. Adjust or Replace Steering Components

Sub-steps:
- Inspect the tie rods for wear; if they are worn, replace them using the following:
  - Loosen the jam nut with a wrench.
  - Remove the tie rod end from the steering knuckle.
  - Install the new tie rod end and tighten to manufacturer specifications.
  - Reattach the jam nut and align the steering.
- Check the rack and pinion for play; replace if necessary by:
  - Disconnecting the steering shaft from the rack.
  - Removing the rack mounting bolts and any attached lines.
  - Installing the new rack and torque bolts to specifications.

4. Inspect Suspension Components

Sub-steps:
- Check control arm bushings for signs of wear or damage.
- Replace any worn bushings by:
  - Removing the control arm from the vehicle.
  - Pressing out the old bushing and pressing in a new one.
- Reinstall the control arm and torque bolts to specifications.

5. Alignment

After replacing or adjusting components, perform a wheel alignment to ensure proper steering geometry.
