Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Allow the engine to cool if it has been running.

2. Inspect and Replace Brake Components (if necessary)

Sub-steps:
1. Remove the wheel using a socket set.
2. Inspect brake pads for thickness; replace if less than 3mm.
3. Check rotors for scoring or warping; replace if necessary.
4. Reassemble the wheel and lower the vehicle.
Tools Required: Socket set, jack stands, brake cleaner.
Safety Warnings: Always use jack stands when working under the vehicle.

3. Inspect CV Joints and Axles

Sub-steps:
1. Lift the front of the vehicle and secure with jack stands.
2. Visually inspect the CV boots for tears or grease leakage.
3. Check for excessive play in the CV joints by moving the axle shaft.
4. Replace any damaged CV joint or axle assembly as necessary.
Tools Required: Socket set, pry bar.
Safety Warnings: Ensure the vehicle is securely supported before working underneath.

4. Transmission Fluid Inspection

Sub-steps:
1. Locate the transmission dipstick and check fluid level.
2. Assess fluid condition; replace if it appears burnt or contaminated.
3. If low, add the correct type of transmission fluid as specified in the owner’s manual.
Tools Required: Funnel, transmission fluid.
Safety Warnings: Keep hands away from moving parts while the engine is running.

5. Check Wheel Bearings

Sub-steps:
1. Lift the vehicle and remove the wheel.
2. Grasp the hub and check for play; any noticeable movement indicates a bad bearing.
3. Replace wheel bearing if any play is detected.
Tools Required: Socket set, bearing puller, torque wrench.
Safety Warnings: Always use safety gear and ensure the vehicle is on a stable surface.
