Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely lifted with jack stands.
Disconnect the battery to prevent electrical issues.

2. Inspect and Replace Brake Components

Sub-steps:
1. Remove the wheel to access the brake caliper.
2. Inspect the brake pads and rotors for uneven wear or damage.
3. If worn, remove the caliper bolts using a socket set and slide the caliper off the rotor.
4. Replace brake pads and/or rotors as necessary, ensuring to apply brake grease on the backing of the pads to reduce noise.
5. Reinstall the caliper and tighten bolts to the manufacturer's specified torque.

3. Check Wheel Bearings

Sub-steps:
1. Spin the wheel by hand to feel for any roughness or grinding.
2. If roughness is detected, remove the wheel hub assembly.
3. Replace any damaged wheel bearings using a bearing puller.
4. Reassemble the wheel hub, ensuring all components are torqued to specifications.

4. Inspect Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick and remove it.
2. Check the fluid level and condition; the fluid should be a clear red color.
3. If the fluid is low or dirty, drain and replace it with the manufacturer's recommended fluid.
