The wheel studs sold by Couplemate are high-tensile.

Yes, however, high tensile steel studs still require checking each morning when travelling. Wear and tear from rough roads has disastrous consequences, as shown in the image below.

How do wheel studs become loose?

Firstly, we rarely see loose wheel studs due to faulty manufacturing. It is important to note that all wheel nuts are tightened correctly.

One loose wheel nut often causes all the wheel nuts to become loose.

Long-distance travel and corrugated road travel mandate checking the tightness of wheel nuts every morning before breaking camp.

Loose Axle U-bolts cause highway havoc.

We are also able to supply custom-made 10″ drums and unbraked hubs.

Is wheel stud sheer common?

Yes, worn wheel studs are more common on caravans than trailers.

The left is a simple example of sheer where the studs can be replaced.

Most reputable caravan and trailer repairers carry wheel studs for common hubs and drums, such as Ford, LandCruiser, and Holden.

When the stud is loose in the hub or drum, the entire part needs to be replaced.

Hole size is critical for the stud knurl to lock into position; therefore, any sign of a loose fit can be expensive.

It is also a good idea to tighten the wheel nuts on your spare wheels. It is not uncommon to lose a wheel on rough trips.

Finally, stripping wheel nuts is uncommon; we do not see it with high-tensile equipment. The stud will shear before a nut will strip its thread.

How can I identify loose wheel nuts?

A very cheap and easy solution for identifying loose wheel nuts is plastic wheel nut indicators.

These indicators slide over the wheel nut and provide a positive indication should the nut move.

There is an excellent article on lug nuts here.
