2002 Toyota Highlander Lug Nut Torque & Bolt Specs

The 2002 Toyota Highlander lug nut torque is 103 Nm (76 ft-lbs), tightened with a 21mm socket on M12 x 1.5 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.

Lug nut torque: 103 Nm (76 ft-lbs) · Socket size: 21mm · Thread: M12 x 1.5.

This page is the OEM-referenced fastener summary for the 2002 Toyota Highlander. 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.

Toyota's engineering standard for wheel torque is unusually consistent across the lineup — nearly every passenger Toyota from the mid-2000s onward specs 76 ft-lbs (103 Nm) for the lug nuts with an M12x1.5 thread and 21mm socket. The big exceptions are the Tundra and Sequoia full-size trucks (97-110 ft-lbs), and the lug studs on older Camrys and Corollas (pre-2002) used a smaller M12x1.25 thread that does not interchange. Always confirm by checking the alloy stamp on the wheel hub if you are unsure.

Common fastener categories on the 2002 Toyota Highlander

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 2002 model-year work: Always use a calibrated torque wrench for safety-critical fasteners, and replace lock washers and crush washers on every 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 2002 Toyota Highlander?

The OEM-specified lug-nut torque for the 2002 Toyota Highlander is 103 Nm (76 ft-lbs), using a 21mm socket on M12 x 1.5 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 2002 Toyota Highlander lug nuts?

The 2002 Toyota Highlander 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 2002 Toyota Highlander 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.
