Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the battery to avoid any electrical issues.

2. Inspect and Replace Power Steering Fluid

Tools Required: Socket set, funnel, power steering fluid.
Check the power steering fluid level using the dipstick or reservoir sight window.
If low, top off with the manufacturer's recommended power steering fluid.
If dirty, drain the old fluid using a turkey baster or fluid transfer pump, then refill with new fluid.

3. Inspect CV Joints and Axles

Tools Required: Jack, jack stands, socket set.
Lift the vehicle and secure it on jack stands.
Remove the front wheels.
Inspect the CV joints for tears in the rubber boot and excessive grease leakage.
If damaged, replace the CV joint or axle assembly.

4. Check Wheel Bearings

Tools Required: Torque wrench, bearing puller.
Spin the wheel by hand to check for roughness or play.
If the bearing feels rough or has excessive play, remove the wheel hub and replace the bearing.
Torque the hub nut to the manufacturer's specifications during reassembly.

5. Inspect Suspension Components

Tools Required: Wrench set, pry bar.
Visually inspect control arms, bushings, and struts for signs of wear or damage.
Use a pry bar to check for play in the bushings.
Replace any worn or damaged suspension components as necessary.
