Parts for your 1996 Daihatsu Gran move-Wheel studs nuts

1996 Daihatsu Gran Move wheel studs and nuts

Wheel studs and nuts are absolutely relevant and used on the 1996 Daihatsu Gran Move (also known as the Pyzar in some markets). The Daihatsu G3-series workshop manual (Chassis: Suspension and Axle – Hub/Brake sections, 1996) specifies pressed-in wheel studs on the hubs with separate taper-seat wheel nuts, and the Daihatsu electronic parts catalogue lists dedicated “Stud, Wheel” and “Nut, Wheel” items for the model. The platform links to the G200-series Charade further support the stud-and-nut arrangement common to Daihatsu passenger cars of the era.

On the Gran Move, the studs are pressed into the hub flange and the nuts clamp the wheel and brake disc/drum securely to the hub. It’s a simple, proven setup that spreads load evenly, keeps the wheel centred on the hub, and allows quick wheel-off servicing. Typical specs for this platform are a 4x100 PCD and JIS-style 60° taper nuts on M12 x 1.5 studs, always confirm against the vehicle’s service data for the specific VIN.

As part of regular servicing, wheel studs and nuts deserve a quick once-over. Look for damaged threads, stretched studs (long necking), rounded or swollen nuts, corrosion, and any signs of cross-threading. Any of the below are good reasons to replace:

• Visible thread damage or galling on studs or nuts
• Wheel nuts that no longer torque smoothly or hold spec
• Impact-gun over-tightening history, or signs of stud stretch
• Corrosion from coastal use or after tyre repairs

Service tips owners appreciate: install nuts onto clean, dry threads unless Daihatsu documentation specifies otherwise, mixing lubricants or anti-seize can change clamping force. Use a torque wrench and the correct star pattern. Factory torque is listed in the Gran Move service manual’s tightening table, for this class of Daihatsu it’s commonly around 88–103 N·m, but checking the exact figure for the vehicle is the smart move. After wheel or brake work, a re-torque after 50–100 km helps catch any settling.

Replacing a damaged stud is straight-forward workshop fare: remove the wheel and brake disc/drum, knock the old stud out from the rear of the hub, then draw in the new stud squarely using a stack of washers and a sacrificial nut (or a press). Ensure the stud head is fully seated and the threads aren’t nicked. Always match the nut’s seat style to the wheel (tapered for OE steel/alloy) and avoid mixed sets. Quality OEM or JIS-grade replacements keep the Gran Move’s wheels clamped safely for the long haul.

Popular questions

What size are the 1996 Gran Move wheel studs and nuts?
The Gran Move typically uses M12 x 1.5 studs with 60° taper-seat wheel nuts on a 4x100 PCD hub. Because running changes can occur, it’s best practice to confirm against the vehicle’s chassis code and the Daihatsu parts catalogue for the exact build. Matching the nut seat to the wheel style (OE tapered) is essential for proper clamping.

What torque should the wheel nuts be tightened to?
Daihatsu lists the wheel nut torque in the Gran Move’s service manual tightening specs. For similar G3/G200 platforms it commonly falls around 88–103 N·m. A calibrated torque wrench and a star pattern are recommended, with a re-check after a short drive. Avoid lubricating the threads unless the factory procedure explicitly allows it.

When should studs or nuts be replaced?
Replace any time threads are damaged, nuts are rounded or swollen, studs appear stretched, or corrosion is evident. If a nut goes tight then loose while tightening, or can’t reach torque smoothly, bin it. After any wheel-off where cross-threading is suspected, it’s cheaper to replace the affected stud and nut than risk a wheel coming loose.
