Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely lifted using jack stands.
Disconnect the battery if working on electrical components.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; top off with the manufacturer-recommended fluid if low.
Inspect for leaks around the reservoir and hoses.

3. Inspect and Replace CV Joints/Axles

Remove the wheel and tire assembly.
Inspect the CV joint boots for tears or grease leakage.
If damaged, proceed to remove the CV joint:
- Remove the axle nut using a socket and torque wrench.
- Disconnect the lower control arm to free the CV joint from suspension components.
- Slide the CV joint out of the transmission or transfer case.
- Install the new CV joint by reversing the removal process.

4. Inspect and Replace Wheel Bearings

Remove the wheel assembly.
Inspect the wheel bearing for play by shaking the wheel.
If worn, remove the brake caliper and rotor.
Use a bearing puller to extract the old bearing from the hub.
Install the new bearing and reassemble components.

5. Check Suspension Components

Inspect ball joints and bushings visually.
If any components are worn or damaged, remove and replace them using:
- A socket set and torque wrench to ensure proper fitment and torque specifications.
