Caravan Wheel Nut Indicators

Caravan wheel nut indicators help identify loose wheel nuts caused by rough dirt roads.

Broken wheel studs on caravan and campers occur regularly on Australia’s open highways.

Occasionally, caravanners will spot the loose nuts and tighten, using a wheel brace, immediately thereby averting catastrophe.

Detached wheels cause damage to the caravan wheel well. After exiting the wheel well, sadly, damage can turn to carnage and occasionally, death.


The best solution to loose wheel nuts and to provide a safety device is to install cheap indicators to provide an obvious answer to the problem.

Install a wheel nut indicator on each wheel for $1 each. The pointer tuned to the 5 o’clock position and nestled close to the hub boss.

Road vibration still causes wheel nuts to loosen and move in an anti-clockwise direction away from the hub boss.

However, owners performing routine morning checks in preparation for the day’s adventures can identify indicators that have moved during the previous day’s adventures.

  • 5/8″ suits 5 Stud Landcruiser.  23mm is the measurement across the flats of the nut.

Wheel nut indicators are no longer restricted to trucks and heavy vehicles.
