Parts for your 2012 Holden Captiva 5-Wheel studs nuts

2012 Holden Captiva 5 wheel studs and nuts: what they do and how to look after them

Wheel studs and nuts are fitted to the 2012 Holden Captiva 5. Technical documentation backs this up: the GM Holden CG Captiva service manual includes a Wheel Stud Replacement procedure describing pressed-in studs and separate wheel nuts, and the GM Service Information for the mechanically related 2012 Chevrolet Captiva Sport/Opel Antara details the same arrangement and refers to wheel nuts torque. So, this Captiva doesn’t use wheel bolts, it uses studs in the hubs with nuts to secure the wheels.

On this model, the job of the wheel studs is to provide sturdy, fixed threads on the hub, while the wheel nuts clamp the wheel and brake rotor hat firmly against the hub face. That clamping force is what keeps the wheel centred and secure while coping with Aussie and Kiwi roads, corrugations, and daily commuting. If the studs or nuts are damaged or under‑torqued, clamping drops, which can lead to brake vibration, wheel wobble, or, in the worst case, a loose wheel.

As part of routine servicing, it’s worth giving the Captiva 5’s studs and nuts a once-over whenever tyres are rotated, brakes are done, or a puncture’s repaired. Look for:

• Damaged or pulled threads, rust pitting, or any sign a stud is spinning in the hub.
• Nuts with rounded hexes, distorted seats, or gritty threads that don’t spin on by hand.
• Corrosion build-up on the hub face that could reduce proper clamping.

Best practice during refit is simple: start all nuts by hand, seat the wheel, then tighten in a star pattern using a calibrated torque wrench to the factory spec shown in the owner’s manual or service information. Avoid lubricating the nut threads unless the manufacturer explicitly calls for it, lubrication changes the torque-to-clamp relationship. A light smear of anti-seize on the bare hub face (not the threads or nut seats) can help prevent the wheel sticking to the hub, which is handy in coastal conditions.

Replacing a damaged stud is straightforward workshop work. Typically the brake caliper and rotor are removed, the broken stud is driven or pressed out of the hub flange, and a new stud is pulled in squarely using appropriate tools. If access is tight, the hub may need to come off. Always replace any suspect nuts at the same time, and recheck torque after 50–100 km of driving.

• Are the Captiva 5’s wheels held on by bolts or by studs and nuts?
  They’re held on by studs and separate wheel nuts. This follows the GM Holden CG Captiva service procedures and GM Service Information for the related Chevrolet Captiva Sport/Opel Antara, which detail pressed-in wheel studs and specify wheel nut torque.
• Is it safe to drive with a missing wheel stud or nut?
  It’s not recommended. Losing even one fastener reduces clamping force and can stress the remaining studs, risking brake pulsation, wheel movement on the hub, or additional fastener failures. Get it repaired promptly.
• What’s the correct way to tighten the Captiva 5’s wheel nuts?
  Start nuts by hand, snug them in a star pattern, then torque them evenly with a torque wrench to the factory specification from the owner’s manual or service data. Avoid using a rattle gun for final torque and recheck torque after 50–100 km.
