Parts for your 1998 Daihatsu Gran move-Wheel studs nuts

1998 Daihatsu Gran Move wheel studs and nuts

Yes — the 1998 Daihatsu Gran Move uses wheel studs and nuts. This setup is confirmed in Daihatsu’s own workshop material for the Pyzar/Gran Move (Chassis: Wheels & Tyres), the Daihatsu Electronic Parts Catalogue (EPC) for G30-series Pyzar/Gran Move, and common industry data sources such as Autodata’s wheel fastener torque listings. The Gran Move runs a 4-stud hub (4x100 PCD) with M12 x 1.5 studs and tapered-seat wheel nuts, not European-style wheel bolts.

On this model, the studs are pressed into the hub and the wheel is secured by nuts. Simple, reliable and easy to service — that’s why Daihatsu stuck with it. The wheel studs provide the clamping force path, and the tapered nuts centre the wheel and keep it snug against the hub face. Keeping these fasteners healthy is critical for safe braking, handling and tyre life.

During routine servicing, a quick visual and torque check goes a long way. Wheel nuts on the Gran Move should be tightened to about 103 N·m (76 lb·ft) on clean, dry threads — a value commonly specified for Daihatsu M12 studs in both factory literature and Autodata. Avoid lubricating threads unless a manufacturer note explicitly says otherwise, as torque specs assume dry threads. After any wheel-off work (tyres, brakes, suspension), it’s good practice to re-check torque after 50–100 km of driving.

Replacement is straightforward if a stud or nut is damaged (stripped, cross-threaded, stretched or corroded). Press the faulty stud out of the hub and draw in a new OE-spec stud, always replace suspect nuts, especially if the taper seat is chewed or the hex is rounded. If you’re fitting aftermarket wheels, confirm the seat type (usually 60° taper) and ensure proper thread engagement — aim for at least 8–10 full turns on an M12 stud.

• Inspect studs and nuts at each service for rust, damaged threads or deformed tapers.
• Clean the hub face and wheel mating surface, avoid paint or rust scale that can relax clamp load.
• Start nuts by hand, snug them in a star pattern, and finish with a calibrated torque wrench (not just a rattle gun).
• Use quality replacement hardware matched to M12 x 1.5 threads and the correct seat profile.

Technical reference points: Daihatsu Pyzar/Gran Move Workshop Manual (Chassis: Wheels & Tyres), Daihatsu EPC (G30-series), and Autodata wheel fastener torque charts all document the use of studs and nuts with typical tightening of ~103 N·m for this platform.

FAQs

What’s the correct wheel nut torque for a 1998 Daihatsu Gran Move?
Most technical references list approximately 103 N·m (76 lb·ft) for M12 x 1.5 wheel studs on this model, applied to clean, dry threads. Use a torque wrench and tighten in a criss-cross pattern. If the wheel has been off, re-check torque after 50–100 km.

How can someone tell if a wheel stud or nut needs replacing?
Look for rounded hexes, chewed or conical-seat damage on the nut, and any rusted, stretched or cross-threaded stud threads. If a nut doesn’t run on by hand or won’t achieve full thread engagement (8–10 turns on M12), replace the suspect parts. Any wheel wobble or repeated loosening after correct torque is also a red flag.

Do aftermarket wheels use the same nuts on a Gran Move?
Often yes, if they use a 60° taper seat and 4x100 pattern, but some aftermarket alloys need different nuts (e.g., different seat type or length). Always match the seat profile and ensure proper thread engagement. When in doubt, ask the wheel supplier or a technician and verify against the vehicle’s M12 x 1.5 studs.
