Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect Power Steering Fluid

Remove the power steering fluid reservoir cap.
Check the fluid level; if low, top up with the manufacturer-recommended fluid.
If the fluid appears dirty or contaminated, proceed to replace it.

3. Replace Worn Steering Components

If any components show signs of wear or damage, such as tie rods or ball joints, replace them:
- Tie Rods Replacement:
  - Loosen the lug nuts and raise the vehicle.
  - Remove the front wheel to access the tie rod.
  - Use a tie rod puller to separate the tie rod from the steering knuckle.
  - Install the new tie rod and tighten to manufacturer specifications.
- Ball Joints Replacement:
  - Remove the wheel and brake caliper if necessary.
  - Remove the retaining bolts for the ball joint and press it out using a ball joint separator.
  - Install the new ball joint and secure it with the proper torque.

4. Inspect and Replace CV Joints if Necessary

Inspect the CV joints for tears or leaks in the protective boot.
If damaged, replace the affected CV joint:
- Remove the wheel and disconnect the axle from the hub.
- Use a CV joint puller to separate the joint from the axle.
- Install the new CV joint and reassemble the hub and wheel.

5. Check and Replace Wheel Bearings

With the wheel removed, check for any play in the wheel bearings by trying to move the wheel side-to-side.
If play is detected, replace the wheel bearings:
- Remove the hub assembly to access the bearings.
- Use a bearing puller to remove old bearings.
- Install new bearings and reassemble the hub.
