Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Gather necessary tools and parts.

2. Inspect and Replace Worn Components

Tools Required: Socket set, torque wrench, jack stands, wheel chocks, screwdriver
Sub-steps:
1. Lift the Vehicle: Use a jack to elevate the front of the vehicle and secure it with jack stands.
2. Remove the Front Wheels: Loosen and remove the lug nuts, then take off the front wheels.
3. Inspect CV Joints: Check the constant velocity (CV) joints for any signs of damage or wear. If damaged, replace with new CV joint assemblies.
4. Check Wheel Bearings: Spin each wheel to feel for roughness or grinding. If bearings are worn, replace them.
5. Inspect Suspension Components: Check control arms, bushings, and struts for damage. Replace any worn or damaged parts.
6. Reassemble: Reinstall the front wheels and torque the lug nuts to manufacturer specifications (typically 80-100 ft-lbs).

3. Fluid Check and Replacement

Tools Required: Funnel, container for old fluid
Sub-steps:
1. Locate Power Steering Reservoir: Identify the power steering fluid reservoir under the hood.
2. Check Fluid Level: Remove the cap and check the fluid level against the dipstick.
3. Replace Fluid if Necessary: If the fluid is low or contaminated, drain it and refill with the manufacturer-recommended power steering fluid.
