Solution

1. Preparation

Tools Required:
- Socket set
- Torque wrench
- Pliers
- Fluid catch pan
Safety Warnings:
- Disconnect the battery before working on electrical components.
- Ensure the vehicle is on a flat surface and securely supported with jack stands.

2. Replace Power Steering Fluid

Place a fluid catch pan under the power steering fluid reservoir.
Disconnect the return hose from the power steering pump and allow old fluid to drain into the pan.
Reconnect the return hose and fill the reservoir with new power steering fluid as specified in the owner's manual.
Start the vehicle and turn the steering wheel from lock to lock to purge air from the system. Check fluid level and top off as necessary.

3. Replace Worn Steering Components

Identify any worn components (tie rods, ball joints, or steering rack).
For tie rod replacement, remove the cotter pin and nut, then use a tie rod puller to detach the tie rod end.
Install the new tie rod end and torque the nut to the manufacturer’s specifications (usually around 50-55 ft-lbs).
For ball joints, remove the wheel and brake assembly, unbolt the ball joint from the control arm, and replace with a new one, securing it with the appropriate torque.

4. Perform Wheel Alignment

After replacing any components, take the vehicle to a professional alignment shop.
Ensure the alignment is adjusted to the manufacturer's specifications for proper steering response.
