2025 Subaru Ascent Lug Nut Torque & Bolt Specs

The 2025 Subaru Ascent lug nut torque is 89 ft-lbs (120 Nm) on M12x1.25 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 5x114.3.

Lug nut torque: 89 ft-lbs (120 Nm) · Thread: M12x1.25 · Bolt pattern: 5x114.3.

This page is the OEM-referenced fastener summary for the 2025 Subaru Ascent. 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.

Subaru lug-nut torque is 89 ft-lbs (120 Nm) on every modern model with an M12x1.25 thread and 19mm socket. Subaru is one of the only Japanese makes still using the smaller 19mm socket — bring it specifically. The boxer engine's drain plug is on the bottom of the block (not the pan) and uses an unusual 17mm head.

Common fastener categories on the 2025 Subaru Ascent

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 2025 late-model work: Modern vehicles increasingly use aluminum body and suspension components. Aluminum fastener torque is typically 60-70% of equivalent steel torque, and aluminum threads strip easily. Use a calibrated torque wrench and apply anti-seize on any steel fastener threading into aluminum.

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 2025 Subaru Ascent?

The OEM-specified lug-nut torque for the 2025 Subaru Ascent is 89 ft-lbs (120 Nm) on M12x1.25 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 2025 Subaru Ascent lug nuts?

Most modern Subaru vehicles use a 19mm or 21mm socket. Older Subaru models from before 2000 may use a 13/16" SAE socket on certain trims. Confirm against the actual lug before purchasing aftermarket wheels.

Are the 2025 Subaru Ascent 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.
