1997 Daihatsu Gran Move Wheel Studs & Nuts

Yes, the 1997 Daihatsu Gran Move (also known as Pyzar, G301/G303 series) uses wheel studs and nuts. This is confirmed in technical references including the Daihatsu Electronic Parts Catalogue (hub/brake sections list “stud, wheel” and “nut, wheel”) and workshop manual hub assembly diagrams for the G3xx platform. Like most Toyota/Daihatsu passenger vehicles of the era, it’s a stud-and-nut arrangement rather than bolt-on wheels.

On this Gran Move, the wheel studs press into the hub flange and the conical-seat wheel nuts clamp the wheel and brake disc/drum firmly to the hub. Their job is simple but critical: provide consistent clamping force, keep the wheel centred, and handle braking and cornering loads without loosening.

As part of routine servicing, owners should give the studs and nuts a quick once-over whenever tyres are rotated or brakes are inspected. Look for stretched or rusty studs, damaged threads, or nuts with rounded hex flats or chewed cone seats. If a stud has been cross-threaded or a nut spins oddly, replace it—don’t try to “chase” badly deformed threads back to life.

• Clean threads with a wire brush, fit nuts dry. Factory guidance for Toyota/Daihatsu family hubs is to avoid lubricants or anti-seize on the threads or cone seats, as this can distort torque readings.
• Tighten in a criss-cross/star pattern to the manufacturer’s specified torque (check the service manual or wheel placard). Re-check torque after 50–100 km following any wheel removal.
• If a stud snaps or spins, the proper repair is to press/pull the old stud out of the hub and seat a new one squarely. Don’t draw a new stud home by over-tightening a nut, use a spacer and hand tools or a press so the serrations seat without damaging the hub.
• When ordering parts, confirm thread size and seat type against the VIN in the Daihatsu EPC, many are M12 x 1.5 with a 60° taper seat, but verify before purchase.

Done right, fresh studs and quality nuts mean the Gran Move’s wheels go on straight, stay tight, and come off easily next time—no dramas at the roadside or during a WOF/rego check.

Popular questions

What size are the wheel studs and nuts on a 1997 Gran Move?
Many Gran Move/Pyzar examples use M12 x 1.5 studs with 60° taper-seat nuts, but there are market and trim variations. The safest approach is to confirm by VIN in the Daihatsu EPC or measure an existing nut’s thread pitch and seat style before ordering.

Can anti-seize be used on the Gran Move’s wheel studs?
It’s not recommended. Lubricants and anti-seize can reduce friction and lead to over-tightening at the same torque setting. Keep threads clean and dry, and torque to spec. If corrosion is present, replace affected studs/nuts rather than masking the issue with lube.

How often should wheel nuts be re-torqued?
Any time a wheel’s been off—after tyre work, brake service, or a puncture repair—re-check torque after 50–100 km. As a habit, have nut torque checked at regular services or when rotating tyres to keep the Gran Move safe and tidy.
