Solution

1. Preparation

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

2. Inspect and Tighten Steering Components

Use a socket set to check and tighten all bolts on the steering rack and column.
Inspect the steering linkage and ensure no components are loose.

3. Replace Worn Components

Tie Rod Ends/Ball Joints Replacement:
1. Raise the vehicle and support with jack stands.
2. Remove the wheel to access the tie rod ends and ball joints.
3. Use a ball joint separator tool to detach the ball joint from the control arm.
4. Remove the tie rod end by loosening the retaining nut.
5. Install new tie rod ends and ball joints in reverse order, ensuring proper torque specifications (typically around 30-50 ft-lbs, but check manufacturer specifications).

4. Inspect Suspension Bushings

Check and replace any worn suspension bushings:
1. Remove the affected control arm if necessary for better access.
2. Use a bushing removal tool to extract old bushings.
3. Install new bushings and reassemble the control arm, ensuring proper alignment.

5. Refill and Inspect Power Steering Fluid

Inspect the power steering fluid reservoir:
1. If low, top off with the recommended fluid type (generally ATF or specific power steering fluid).
2. Check for leaks in the power steering lines and rack.
