Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, flat-head screwdriver, funnel.
Safety Warnings: Ensure the vehicle is on a level surface, and use jack stands to secure the vehicle after lifting it.

2. Inspect and Replace Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; add fluid if low.
If the fluid is dirty or contaminated, drain and replace it.
Refill with the recommended power steering fluid type.
Start the engine and turn the steering wheel from lock to lock to bleed air from the system.

3. Examine and Replace CV Joints or Axles

Lift the vehicle and secure it with jack stands.
Remove the front wheels for better access.
Inspect the CV joints for torn boots or grease leakage.
If damaged, remove the axle nut using a socket wrench.
Disconnect the CV joint from the transmission and remove the axle.
Install the new axle by reversing the removal steps, ensuring it is properly torqued.

4. Inspect and Replace Wheel Bearings

Remove the brake caliper and rotor to access the hub assembly.
Check for play in the wheel bearing by rotating the hub; it should spin smoothly without noise.
If worn, remove the hub assembly using a socket set.
Press out the old bearing and press in a new one.
Reassemble the hub, rotor, and brake caliper, torquing all bolts to the manufacturer’s specifications.

5. Check and Repair Suspension Components

Inspect control arms, ball joints, and bushings for wear or damage.
Replace any components that show signs of excessive wear.
Reassemble and ensure all bolts are properly torqued.
