Tools Required: Fluid pump, funnel.

3. Inspect and Replace Worn Suspension Components

Sub-steps:
1. Lift the vehicle securely using jack stands.
2. Remove the wheels for easier access to suspension components.
3. Visually inspect control arms, bushings, and tie rod ends for any signs of wear or damage.
4. If any components are damaged, replace them using a socket set and torque wrench to the manufacturer’s specifications.
Tools Required: Jack, jack stands, socket set, torque wrench.

4. Inspect and Replace CV Joints

Sub-steps:
1. Check the CV joint boots for tears or leaks.
2. If damaged, remove the axle by unbolting it from the wheel hub and transmission.
3. Replace the CV joint and reassemble, ensuring all bolts are torqued to specifications.
Tools Required: Socket set, pry bar.

5. Check and Replace Wheel Bearings

Sub-steps:
1. Spin the wheel while the vehicle is lifted to check for noise or roughness.
2. If noise is present, remove the wheel and hub assembly.
3. Replace the wheel bearing using a bearing puller and reassemble.
Tools Required: Bearing puller, socket set.
