Parts for your 1999 Nissan Navara-Wheel studs nuts

1999 Nissan Navara wheel studs and nuts

The 1999 Nissan Navara (D22 series) does use wheel studs and nuts. That’s the factory setup on its 6-stud hubs, as outlined in Nissan’s D22 Service Manual (Wheels and Tyres section) and reflected in the Nissan FAST parts catalogue and common aftermarket fitment data for the 6x139.7 PCD hub pattern. So, wheel studs and nuts are absolutely relevant for servicing and replacement on this ute.

On the Navara, the studs are press-in fasteners in the hub, and the wheel nuts clamp the wheel securely to the hub face. Their whole job is to provide reliable clamping force so the wheel stays centred and tight under braking, cornering and heavy loads — classic ute duties. For most D22 variants, the studs are M12 with a fine thread (commonly M12 x 1.25) and a 60° conical-seat nut, always confirm by VIN or measuring before ordering parts, because market and trim differences exist.

Servicing’s pretty straightforward. Keep the threads clean and dry — no grease on the threads or the cone seat unless the specific service data for your market says otherwise. Use a torque wrench to tighten the nuts in a star pattern, and avoid hammering them home with a rattle gun. Typical wheel nut torque published for similar D22 applications sits around 100–120 N·m, but owners should follow the exact figure in the owner’s manual or service manual for their build. After a wheel’s been off, a re-torque after 50–100 km is good practice.

Common signs it’s time to replace studs or nuts include damaged or stretched threads, a nut that won’t hold torque, a stud that spins in the hub, or visible corrosion and pitting (especially on coastal utes). Chrome-capped nuts that swell or crack are worth binning. If a stud snaps or strips, press in a new one with the correct knurl diameter and shoulder length so it seats fully in the hub. When corrosion or over-torqueing has affected more than one fastener, replacing the full set on that wheel — and sometimes the opposing wheel on the same axle — helps keep clamping consistent.

Quick tips owners appreciate:

• Always start nuts by hand to avoid cross-threading.
• Tighten in a star pattern and finish with a torque wrench.
• Clean the hub face and wheel mating surface to prevent loosening.
• If running aftermarket wheels, use the correct-seat nuts and verify stud engagement.

Popular questions

What size are the wheel nuts on a 1999 Navara?

Most D22 Navaras use M12 x 1.25 studs with conical-seat nuts and a 21 mm hex. Because there were market differences and plenty of aftermarket wheel options, it’s smart to confirm the thread pitch and seat style before buying replacements.

What torque should the wheel nuts be tightened to?

A typical spec for D22 Navara wheel nuts is in the 100–120 N·m range, but the exact figure depends on the variant and market. The safest bet is to follow the torque in the owner’s or service manual and re-check after 50–100 kilometres.

Can a single damaged wheel stud be replaced?

Yes. A single damaged stud can be pressed out and a new one pressed in with the hub supported. If one has failed due to corrosion or over-torqueing, inspect the rest, replacing multiple studs or the full set on that wheel can save grief later and keep the clamping even.
