The rocker panels, rear wheel arches, and even the cab corners are susceptible to severe corrosion. This is often more than just a cosmetic flaw, compromising structural integrity. Repairing extensive rust can involve cutting out and welding in new metal, costing anywhere from $1,000 to $3,000 per side, depending on the extent of damage. Buyer tip: Thoroughly inspect these specific areas, looking for bubbling paint, holes, or visible rust during daylight hours and consider the vehicle's history in salty climates.

WHAT TO CHECK BEFORE YOU BUY

1. Engine Noise: Start the truck cold and listen for any ticking, knocking, or prolonged rattling. Pay particular attention to the 5.4L Triton and 3.5L EcoBoost engines.
2. Transmission Operation: During a comprehensive test drive, observe all gear changes for smoothness, delays, or harsh clunks, especially in lower gears and during deceleration.
3. Oil Condition: Pull the dipstick and check for proper oil level, color, and consistency. Milky residue indicates potential coolant contamination, while excessively dark or sludgy oil suggests neglect.
4. Coolant Reservoir: Inspect the coolant level and color in the reservoir. Look for any oil contamination or sediment, which could signal head gasket or oil cooler issues.
5. Body Rust: Carefully inspect the rocker panels, wheel arches, cab corners, and tailgate for any signs of bubbling paint, rust holes, or repairs that might mask underlying corrosion.
6. 4WD Engagement: If equipped, engage 4-wheel drive in both high and low ranges in a safe area to ensure the system operates smoothly without grinding, binding, or clunking sounds.
7. Rear Window Seal (SuperCrew): Check the interior headliner around the rear window for water stains, which indicate a leaking seal requiring replacement, a common issue on SuperCrew models.

COST OF OWNERSHIP OVER 5 YEARS Owning a used Ford F-150 involves a range of expenses beyond the initial purchase price. Typical annual maintenance, including oil changes, tire rotations, air filter replacements, and brake inspections, generally costs between $500 and $1,000. However, expect to allocate an additional $1,000 to $2,000 per year for potential major repairs, especially if purchasing an older model or one with higher mileage, as issues like those detailed above are not uncommon.

Fuel costs represent a significant ongoing expense.
