Thread: Disco Wheels on Caravan ?

all the local guys on my small town are telling me its to hard and cant be done. When i used to live in brisbane i could get pretty much anything done, but its all too hard down here

anyone had any luck changing the bolt pattern of an existing axle.

p.s. it has a drop axle with what looks like torana or hq drum brake assemblies on it. i heard commodore is the same stud pattern but with different wheel stud diameter. maybe i can put commodore drums on and get the studs drilled and changed. also maybe going treg hitch so maybe i should just go electric brakes.

Speak to a local Trailer manufacturer in your area.
Hubs are generally made to take GMH or Ford bearings, and the exterior is blank.
The stud patterns can be made to suit ANY vehicle, usually by a computer operated lathe.

When I was working in the Camper trailer business, we could get wheel hubs spun to suit any car or 4WD

Do a search on the forum as there are a few guys that have matching D2 rims on their trailers.

This is a frequent question so yes there are a few threads on the issue.

Best idea is to pop off one of the wheels and take a look at the brand of brakes on the caravan/camper. They will probably be AlKo, then go to your local trailer parts place or a good auto accessories shop and check your D2 rims against the commodore PCD hub/drum assembly.

Your big problem is going to be the GTM (gross trailer mass), this is limited by the type or bearings on the hub (which is not necessarily the same as the wheel it fits)

• Holden bearings are only rated at 1000Kg/axle.
• Ford or "slimline" bearings are only rated at 1450Kg/axle.
• Land Cruiser or "parrallel" bearings are rated at 2 tonnes +/axle.

Un-mutilated Disco 2 rims will not fit over a parallel bearing hub.

Just to add to this.
ALKO will not supply metric studs, so DO NOT try to have ALKO do the job if you want to fit Disco Mags as you will not be able to get nuts to fit .
Ask me how I know.

What I did with my RRC mags in the end was have the hubs redrilled by a local engineeering shop at Erina ( the owner owns a 130), and I bought Rover studs and fitted them myself.

TIP the parallel electric hubs are very thick , so you may have to have a counterbore to have the Rover studs long enough, if you have electric hubs.
So,
1 buy blank hubs/drums
2 have the holes drilled by an Engineering shop
3 Buy Rover studs and have them fit them or fit them yourself.
4 Make sure the studs are long enough by counterboring the hubs if necessary.
5 As posted above you may have to modify your wheels.

Philip, was it RRC studs you used and were they long enough for the hubs being used ? I have a pair of transit pattern hubs which are same pcd but with smaller studs, i have a couple of RRC studs so will only need a few more for a complete set - i thought i might need longer studs as the flange is approx 1/2 " thick.

YES I used RRC mag wheel studs. The ALKO studs by the way have a comparatively larger spline diameter than the RRC studs, so measure them and you may find the RRC stud fits the hole. There should be 1MM interference. Just bash the ALKO stud out with a hammer.

In my case I measured the "emerged" length of the stud from the face of the hub on the car, then I had the Engineering shop countersink/bore a larger hole to the correct depth in the trailer hub, so that the stud was "countersunk" and had the same length available for the nut.

In any case if it is an electric hub the stud has to be countersunk.

Is the Disco2 stud the same as a RRC.? I thought they were smaller.

Yes D2 stud is smaller, mine are for D1 steel rims.

You can really disregard all this if you are fitting steel rims, as the you can use ALKO imperial studs with their nuts.
They will do large studs and supply nuts to suit.
Its only if you use mags that you have the unique problem as the nuts are unique and unobtainable in imperial.

I have a set of imperial studs and steel wheel nuts if you want them cheap. PM me and I will look for the bloody things. They cost me three months of anguish and a lot of money!

BUT I am confused. Your original post said D2.
