Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Brake Components

Sub-steps:
1. Remove the wheel using a socket set.
2. Inspect brake calipers for sticking; if they are seized, replace them.
3. Remove the brake pads and inspect them for wear; replace if necessary.
4. Check the brake rotors for warping; resurface or replace if out of specification.
5. Reassemble the brake components and wheel, torquing lug nuts to manufacturer specifications.

3. Check and Inflate Tires

Sub-steps:
1. Use a tire pressure gauge to check the pressure of all tires.
2. Inflate any under-inflated tires to the recommended PSI found on the driver’s side door jamb.
3. Inspect tires for any bulges or uneven wear; replace if necessary.

4. Inspect and Change Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick and remove it to check fluid level.
2. If fluid is low, add the recommended transmission fluid type.
3. If fluid appears dark or burnt, drain and replace the fluid using a transmission fluid pump.
4. Recheck fluid levels after replacement.

5. Inspect Wheel Bearings and Drivetrain Components

Sub-steps:
1. Jack up the vehicle and remove the wheels.
2. Spin the hub assembly to check for roughness or noise indicating bad wheel bearings.
3. If bearings are faulty, remove the hub assembly and replace the bearings using a bearing press.
4. Inspect driveshaft and CV joints for damage; replace as necessary.
