Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical issues.

2. Inspect and Replace Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; if low, top off with manufacturer-recommended fluid.
If the fluid is dark or contaminated, drain the system and refill with new fluid.

3. Inspect and Replace Steering Components

Raise the front of the vehicle using a jack and secure it with jack stands.
Remove the front wheels to access the suspension and steering components.
Check the tie rod ends for wear; if worn, replace them by:
- Loosening the nut and removing the tie rod end from the steering knuckle.
- Installing the new tie rod end and tightening to the manufacturer's torque specification.

4. Inspect and Replace CV Joints

Check the CV joints for damage or torn boots.
If damaged, remove the axle by:
- Disconnecting the lower control arm from the steering knuckle.
- Removing the axle nut and pulling the CV axle out of the transmission.
- Installing the new CV axle and securing it with the axle nut.

5. Check and Replace Wheel Bearings

Spin the wheel to listen for grinding noises indicating bad bearings.
If necessary, replace by:
- Removing the wheel and brake assembly.
- Using a bearing puller to remove the old bearings.
- Installing new bearings and reassembling components.
