1999 Daihatsu Gran Move wheel studs and nuts: what they do and how to look after them

Wheel studs and nuts are absolutely relevant on the 1999 Daihatsu Gran Move. Technical references back this up: the Daihatsu Electronic Parts Catalogue for the Gran Move/Pyzar (G3-series) lists press-in “wheel studs” and matching “wheel nuts” on both front and rear hubs, and the factory Workshop Manual’s Wheels and Tyres section specifies a wheel nut tightening procedure and torque. Major aftermarket catalogues used across Australia and New Zealand also carry replacement wheel studs and wheel nuts specifically for the 1996–2002 Gran Move/Pyzar. Put simply, this model uses studs pressed into the hub, and the wheel is secured with separate nuts.

On this little MPV, the wheel studs and nuts do the straightforward but critical job of clamping the wheel evenly to the hub. Good clamping keeps the brake rotor located, prevents vibration, and stops the wheel from fretting on the hub face. Over time, studs can stretch or the threads can cop a hiding from rattle guns, nuts can round off or the taper seat can score. That’s why they deserve attention at service time.

For routine servicing on a 1999 Daihatsu Gran Move, it’s smart to:

• Clean the hub face and wheel mating surfaces so the nuts achieve correct clamping without debris throwing out torque.
• Inspect each stud for damaged or pulled threads, corrosion (especially on coastal vehicles), and any sign of bending. Replace any suspect stud—don’t try to “chase” badly damaged threads.
• Check wheel nuts for cracked tapers, rounded hexes, or stretched threads. Replace damaged nuts as a set on that wheel.
• Refit wheels by hand-threading the nuts first, then tighten in a star pattern with a torque wrench. Avoid lubricating the threads or seats unless the service data for the vehicle explicitly allows it.
• After tyre or brake work, recheck nut torque after 50–100 km of driving.

Replacing a worn stud on the Gran Move involves pressing or drawing the old stud out of the hub flange and pulling a new one in square with washers and a spare nut, or using a press with the hub off the car. If more than one stud on the same hub is suspect, replacing them as a group is good insurance. Always support the vehicle safely with stands, and if a nut won’t hand-thread easily, stop—cross-threading a good stud will quickly turn it into a bad one.

Popular questions

Do all 1999 Daihatsu Gran Move models use wheel studs and nuts?
Yes. Across the Gran Move/Pyzar range for this era, the hubs use press-in wheel studs with separate nuts rather than European-style wheel bolts. This matches the setup described in the Daihatsu parts catalogue and workshop procedures for wheel removal and refit.

How tight should the wheel nuts be on a Gran Move?
Daihatsu specifies a torque in the workshop manual for the model, use a quality torque wrench and a star pattern. If the exact figure isn’t on hand, check the owner’s handbook or a trusted service database before tightening. Avoid rattle guns for final torque, and don’t oil the threads unless the service data specifically calls for it.

When should wheel studs or nuts be replaced?
Any time threads are damaged, a nut won’t hand-start smoothly, the stud looks stretched or bent, or the nut’s taper is cracked or chewed up. After any event where a wheel has run loose, replace the affected studs and nuts on that hub—once clamping is compromised, it’s cheap peace of mind to renew them.
