2015 Ford Expedition Lug Nut Torque & Bolt Specs

The 2015 Ford Expedition lug nut torque is 150 ft-lbs (200 Nm), tightened with a 21mm socket on M14x2.0 studs. Torque in a star pattern in two passes (snug, then final), and re-check after the first 50–100 miles of driving. Use a calibrated torque wrench — not an impact gun — for the final pass. The wheel bolt pattern is 6x135.

Lug nut torque: 150 ft-lbs (200 Nm) · Socket size: 21mm · Thread: M14x2.0 · Bolt pattern: 6x135.

This page is the OEM-referenced fastener summary for the 2015 Ford Expedition. Use it before any maintenance or repair job where torque values matter — brake work, wheel changes, suspension service, engine teardowns, or oil changes. Specs are pulled from manufacturer service literature, cross-checked against community data, and updated as new chassis variants become available.

Ford lug-nut torque varies more by chassis than most makes — 100 ft-lbs for Focus/Fusion/Fiesta, 150 ft-lbs for half-ton F-150, and 165 ft-lbs for Super Duty F-250/F-350. F-150s from 2004-2014 use a 21mm OEM socket, while 2015+ aluminum-body trucks moved to the larger 22mm. Ford torque-to-yield (TTY) head bolts are standard from the early 2000s — do not reuse them, ever.

Common fastener categories on the 2015 Ford Expedition

Wheel / lug nut torque and thread spec (covered above)
Brake caliper bracket bolts (typically 80-130 ft-lbs) and slide/guide pins (18-35 ft-lbs)
Engine oil drain plug torque — rarely above 30 ft-lbs; always use a new crush washer
Transmission pan, valve cover, and intake manifold bolts (low torque, often 89-106 in-lbs)
Suspension control arm, sway bar, tie rod end and ball joint torque
Spark plug torque (typically 10-15 ft-lbs on aluminum heads — do not exceed)
Differential cover bolts (RWD/4WD only) and transfer case fasteners

Repair guidance for this model year

For 2015 model-year work: This era introduced widespread torque-to-yield (TTY) bolts on head, main, and crank pulley fasteners. TTY bolts stretch permanently when torqued and must not be reused — the spec calls for a fresh bolt every time. Always verify TTY status against the FSM before reassembly.

Tools you will need

Metric socket set (8mm-22mm), 6-point impact-rated
Calibrated torque wrench (10-150 ft-lbs covers most automotive jobs; add a 0-250 ft-lbs wrench for truck lug nuts)
Breaker bar (24" minimum) for initial loosening
Penetrating oil (PB Blaster or Kroil) for any fastener over 5 years old
Anti-seize on stainless or dissimilar-metal threads; thread-locker (Loctite blue) on critical reassembly

Frequently asked questions

What is the lug nut torque on a 2015 Ford Expedition?

The OEM-specified lug-nut torque for the 2015 Ford Expedition is 150 ft-lbs (200 Nm), using a 21mm socket on M14x2.0 thread studs. Use a calibrated torque wrench in a star pattern, in two passes (50% and 100%), and re-check after 50-100 miles of driving.

What socket size do I need for the 2015 Ford Expedition lug nuts?

The 2015 Ford Expedition uses a 21mm socket. A 6-point impact-rated socket is recommended over a 12-point chrome socket — 12-points round off lug nuts under impact-driver use.

Are the 2015 Ford Expedition fasteners metric or SAE?

Metric is the standard for this vehicle. Most fasteners on this vehicle are metric (M6, M8, M10, M12, M14). Bring a full metric set; SAE substitutes can round the head. Bolt-head markings are the fastest way to confirm grade and material at the bench.
