Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to avoid any electrical issues during the repair.

2. Inspect and Replace CV Joints

Tools Required: Socket set, torque wrench, pry bar, CV joint grease.
Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the front wheel to access the CV joint.
3. Use a socket set to remove the axle nut and disconnect the CV joint from the wheel hub.
4. Slide the axle out of the transmission or differential (ensure to support the transmission if necessary).
5. Inspect the CV joint for any signs of wear or damage. If damaged, replace it with a new CV joint assembly.
6. Apply CV joint grease and reassemble in reverse order, ensuring to torque the axle nut to manufacturer specifications.

3. Check and Replace Steering Components

Tools Required: Wrench set, torque wrench, ball joint separator.
Sub-steps:
1. Inspect the steering linkage and suspension components for wear or looseness.
2. If any components (tie rods, ball joints) show signs of wear, remove them using a ball joint separator.
3. Replace worn components with new OEM parts.
4. Reassemble all components and torque to specifications.

4. Refill and Test Power Steering Fluid

Tools Required: Funnel, power steering fluid (as specified by manufacturer).
Sub-steps:
1. Check the power steering fluid reservoir for proper fluid level.
2. If low, refill with the recommended power steering fluid.
3. Start the engine and turn the steering wheel from lock to lock to bleed any air from the system.
