2008 Infiniti Ex35 Lug Nut Torque & Bolt Specs

The 2008 Infiniti Ex35 lug nut torque is 98 ft-lbs (133 Nm), tightened with a 21mm socket on M14x1.25 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.

Lug nut torque: 98 ft-lbs (133 Nm) · Socket size: 21mm · Thread: M14x1.25.

This page is the OEM-referenced fastener summary for the 2008 Infiniti Ex35. 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.

Nissan lug-nut torque is 83 ft-lbs (113 Nm) for nearly every passenger model since 2000 with an M12x1.25 thread (note: tighter pitch than Toyota/Honda's M12x1.5 — the lugs do not cross-thread cleanly with neighboring makes). Socket size is 21mm. Titans and Armadas use a larger M14x1.5 thread at 133 ft-lbs.

Repair guidance for this model year

For 2008 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
