2. Using a clean funnel, pour in new fluid until the proper level is reached.
3. Replace the cap securely.

3. Check and Replace CV Joints if Necessary

Tools Required: Jack, jack stands, socket set, torque wrench.
Lift the front of the vehicle and secure it with jack stands.
Inspect the CV joints for tears in the boots or excessive play.
If damaged, replace the CV axle:
1. Remove the wheel and tire assembly.
2. Disconnect the lower control arm from the knuckle.
3. Remove the axle nut and pull the CV axle out of the transmission and hub.
4. Install the new CV axle by reversing the removal steps and torque the axle nut to manufacturer's specifications.

4. Inspect and Replace Wheel Bearings if Necessary

Tools Required: Jack, jack stands, socket set, bearing puller.
While the vehicle is lifted, check the wheel bearings for play by wiggling the wheel.
If excessive play is detected, replace the bearings:
1. Remove the wheel.
2. Remove the brake caliper and rotor.
3. Use a bearing puller to remove the old bearing.
4. Install the new bearing, making sure to pack it with grease.
5. Reassemble the brake components and wheel.

5. Inspect and Replace Suspension Components if Necessary

Tools Required: Jack, jack stands, socket set, torque wrench.
Check the control arms and bushings for signs of wear or damage.
If any components are worn:
1. Remove the damaged component from the vehicle.
2. Install the new component, ensuring to torque bolts to manufacturer specifications.
