Solution

1. Preparation

Park the F-150 on a level surface and engage the parking brake.
Gather necessary tools: jack and jack stands, socket set, torque wrench, and fluid containers.

2. Inspect and Replace Brake Components

Sub-steps:
1. Remove the wheel using a socket set.
2. Inspect brake pads for wear; replace if less than 1/8 inch thick.
3. Check rotors for scoring or warping; replace if damaged.
4. Reinstall wheels and torque to manufacturer specifications (usually around 100-150 lb-ft).

3. Check and Adjust Differential Fluid

Sub-steps:
1. Remove the differential cover using a socket set.
2. Inspect gears for wear or damage; replace if necessary.
3. Drain old fluid and clean the cover; replace gasket if damaged.
4. Refill with the manufacturer-recommended fluid (typically 75W-90).

4. Transmission Fluid Service

Sub-steps:
1. Remove the transmission pan using a socket set.
2. Drain old fluid and replace the filter.
3. Clean the pan and reinstall it with a new gasket.
4. Refill with the appropriate transmission fluid (usually Mercon LV for Ford).
