Thread: Camper trailer hub conversion

I have read this in one of your posts before but is it legal in Australia?
I'd be worried a nut holding the adapter on may come loose or break a stud.
Being in behind the wheel it would not be seen and could lead
to bigger issues.
Cheers, Kyle.

Well they have done a lap including the GRR and no problems. Yes they are technically illegal on a CAR although several cars do have them from new eg Porsche 924 turbo , but so is machining a D2 wheel. Only in Australia BTW not in USA or UK.
I have never heard of a RRC under normal conditions (let alone on a camper weighing 700Kgs or around half the wheel loading of a RRC) breaking a stud as they are enormous. I must say I carefully prepared the hubs by wire wheeling all rust and scale from them before fitting the adapters.

I preferred to keep the wheels legal as there would be very little meat left between the opening and stud holes and the consequences of a wheel failing while on a car would be far greater than an adapter coming loose on a camper trailer.

AFAIK there has been NO loosening of the RRC nuts but I intend to check them and do the bearings before another trip away.

To each their own but the question was asked and I haven't seen another way to do it on an existing trailer using parallel hubs.

BTW I believe the tapered hubs on the pictured trailer have an insufficient safe load rating for offroad use according to trailer building guidelines that I read to double the load rating of the axle for offroad use.
