Thread: D2 Disc Hubs for my camper

Now there aren't any photos for this at the moment, but i'll descibe what i've done to get the same stud pattern on the camper as the tow car, many may think this is easy and yes it is if you have a Defender or Disco 1, Land Cruiser, Patrol, Holden and so on, but for those of us that have a D2 or P38a, it is a PITA.

This also for those who have the current model RRS and D3.

This is for those who want the trailer to have matching wheels for that extra spare when travelling in the bush and to make them look a little better and match the car.

The biggest, and ONLY problem is the stud size of 14mm on the D2, trailer manufacturers will only use 12mm for cars or 9/16 for 4WDs in their trailer hubs, some camper trailer mobs will do it when buying a new camper, but for getting the hubs after, NO WAY.

This is the frustrating bit, they can do it when buying a new camper, but not if buying the hubs only

So this is what i did, i purchaced Holden Commodore trailer disc hubs, pressed out the 12mm holden studs, got a 5/8 drill bit, (9/16 drill bit is a tad to small to use) linished it under size approx 1mm but not quite to get a tight fit (it's essential at this point you do test holes on something other than the new hubs to be certain first of a tight fit)
Then once i did my test holes and pressed the D2 studs in to the test holes to insure a tight fit, i drilled the holes out on the Commodore hubs.

Any LR workshop will know where to get the D2 studs.

After this i then pressed them into the Commodore disc hub, i used grease to help them go in as it is a tight fit.

And there you go, done.

Why Commodore disc hubs, well, they have the same PCD as the D2, put in Ford heavy duty bearing as that's what my trailer axle is made for, then buy the caliper brackets grind off my drum brake brackets and weld the new caliper bracket to the axle and bolt them on.

One thing i didn't mention is that some trailer companies will make you hubs, but they will not put D2 studs in the hubs, they will only put 9/16 studs in, this is fine if your using steel rims on your trailer, but if you do you can't use the Disco rims on the trailer if you get a flat and visa versa, although in an emergency if you or another vehicle had spare 14mm wheel nuts for D2 steel rims it may get you out of trouble by putting the steel rim on your D2, but if you get a flat on the trailer, your stuffed, because you can't use the Disco alloy on the trailer.

Have done a trial fitting and the P38a alloys on the trailer i got to match the Disco alloys fit perfectly on the new Commodore disc hubs, no grinding was needed, so all is good.

Photos will be on soon.

Just for info I have found the VE Commodore studs are 14mm (same as D2) and will work for steel or alloy wheels.

Genuine Holden bit @ $8.00 each. from any holden dealer or $12.00 each from Tyre Power!

I just specified blank hubs with the big bearings and and had my local engineering shop drill and fit the studs for 120mm PCD (commodore prior to VE) cost $50.00 Bargain

That's good to know, is the VE a different PCD to previous model Commodores

I did a fitting using the P38a alloys i have on the trailer, fit perfectly, i thought i would have to grind the centre of the alloys to fit over the bearing housing but no need too.
