3. If low, add the manufacturer-recommended transmission fluid.
4. If the fluid is dark or burnt, drain the transmission fluid using a fluid pump.
5. Replace with fresh transmission fluid and check for leaks.
Tools Required: Fluid pump, funnel, transmission fluid.

3. Inspect and Replace CV Joints/Axles

Sub-steps:
1. Safely lift the vehicle using jack stands.
2. Remove the wheel on the side with suspected CV joint issues.
3. Inspect the CV joint boots for cracks or tears.
4. If damage is found, remove the axle nut and disconnect the CV joint from the hub.
5. Replace the CV joint or entire axle if necessary.
6. Reassemble the wheel and lower the vehicle.
Tools Required: Socket set, torque wrench, pry bar.
Safety Warnings: Ensure the vehicle is securely supported before working underneath it.

4. Check Wheel Bearings

Sub-steps:
1. Rotate the wheel by hand to check for roughness or noise.
2. If noise is present, remove the wheel and inspect the bearing for play.
3. If necessary, replace the wheel bearing, following manufacturer specifications for assembly.
Tools Required: Bearing puller, socket set.
Safety Warnings: Wear safety glasses to protect eyes from debris.
