D2 Disc Hubs for my camper

[Redback]

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:twisted: 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:twisted:

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.

What about a 19/32" or 15mm drill? :p

Maybe if you left it in the car, you wouldn't forget it:rolleyes:

[Redback]

Well the good news is no grinding of the factory alloys or the trailer alloys, as the Commodore disc hubs fit perfectly:D:banana::banana:

Hi Bazz
The mob I used did fit 14mm studs,I had to provide them.
If I used the discs I would have got away from having to grind the alloy wheel too,but I wanted electric brakes so the disc option was out.

Yep i wanted electric as well, but these came up at a bargin price so i snspped them up, maybe sometime down the track when electric discs become more popular and cheaper i go electric then, but for now these will do:D

Hi there,
I'm doing the D2 trailer hubs also.

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:confused:

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.

Not much point - I can't use it on the P38A. :(

Wait on, with the Kaymar rear bar, maybe I could!

Ron

[strangy]

Yep, the VE commodore has a different PCD to all other Commodore models.
Coulnd't tell you what it is though.

Yes you can Ron, the Kaymar has hilift jacking points.

We have VEs at work, i'll check them out.

Wheel warning for Commodore

The Drive Team, The Sydney Morning Herald, 15/12/06







Holden has told its dealers that the new VE model's wheels won't fit old Commodores.

https://www.aulro.com/afvb/images/imported/2007/09/82.jpg
Holden VE Commodore: production line at the Elizabeth factory in Adelaide.


When Holden introduced the all-new VE Commodore in August it changed some crucial dimensions of the wheel-locating system. This was done to avoid confusion on the production line (as the Holden factory will be building both new and old models for some time yet) and to cope with the new Commodore's extra weight, width and grip levels.
Holden sent the following statement to Drive on Wednesday: "Fitting VE wheels onto a VZ [or earlier model Commodore] is not recommended or condoned by GM Holden as it raises some safety concerns as there are two major differences in the wheels."
Holden said the VE Commodore has 14mm wheel studs and earlier Commodores have 12mm wheel studs.
"If a VE wheel were fitted onto a VZ [or earlier model Commodore] there is a concern that there would not be enough bearing area under the retention nut on the aluminium wheel, which, worse case scenario, means the wheel could potentially fall off."

Aaaaarrrr so it's only the wheel stud that is different, basicly it's the same as the Disco, i wonder if the thread pitch is the same:unsure::unsure:

I had a look at the rims on the VE at work yesterday and they look as if they have the same offset as the Disco steel rims.

Might do a trial fitting one day, they are 16s too.

[Slunnie]

The 14mm stud matches the disco wheel nut also doesn't it?

are you saying that you can get a kaymar rear bumper for a rangerover p38????

Not any more. But mine has one.

Sorry for my ignorance on this, but in summary, does this mean that if I fit VE hubs to my trailer, I can use D2 wheels??

Bump :angel:

[Redback]

OK I finnally got around to seeing if the new Commodore wheel nuts and studs are the same pitch and thread as the D2 AND yes they are, got a wheel nut from a new Commodore (mag wheel) and put it on the stud from my camper and bingo fits perfectly.

Baz.

[Hastykiwi]

Does this mean a commodore 16" wheel will fit a D2? Go easy on me here as I am assuming a great deal here, like, they make a commodore 16" wheel. etc.

Yes and Yes the new Commodore VX/VY has 16" rims.

Baz.

[Hastykiwi]

OK, so does this mean any commodore 16" 5 stud rim will fit, or are there restrictions in terms of the models they come off.. i'm assuming that commodore rims are relativley cheap compared to the ridgey didge LR option.

Nick

[waz]

Hi Nick,

I don't think Commodore wheels will on a DiscoII because of wheel offsets. But if you get hubs from a late Commodore and put them on a trailer, Disco II wheels will then fit.

Please correct me if I'm wrong.

only if the wheel center is big enough for the hub end cap - that was the problem with doing this for d2 wheels with the old commodore hubs (pattern was right but had to change the studs as commodore was 12mm) the wheel needed to be machined, and some here will say that that won't work - but there are many (i owned one) running around like that

actually will still have to change the studs as trailer parts are imperial so you will get 9/16 studs... unless you use automotive parts.

14MM studs are available for trailers, from any good trailer specialist, there should be no need to put 9/16 studs on, I have 14MM on my camper trailer AND I also have them on my new disc hubs that I will be fitting soon, also I have D2 rims on my camper and they fit well and the centre hole is much bigger than the centre cap on the hub, it's not an issue on a trailer.

Only the new VX/VY 2008/09 Commodores have 14mm wheel studs so only the rims off these are suitable (no drilling out of stud holes)

Acually any trailer place that makes hubs, should be able to make trailer hubs in the 120PCD with 14mm studs, if they make commodore hubs for trailers then it's only a matter of making the stud holes to suit a 14mm stud, after all melbourne trailer made mine no trouble and Martins in WA made Landyandys no trouble either, so i don't see what all the fuss is about.

do you mean vx/vy and 2008/09 commodores cos their is a VZ after that then the VE . VX came out 2000 i think and the VY was 2002 . VE came out 2008 .

No, I mean whatever the current Commodore is, 2008/09 only, sorry I'm not up on the prefexs on Holdens these days.

[DiscoDan]

So I got to buy Holden stuff for my trailer, I sort of can live with that (just) Saying that my trailer has Tojo 5 stud but I might change now.

Forgetting wheel offset, I am not sure as to whether a commodore wheel would handle the weight or off road stresses. I am sure someone would enlighten us all.

After going thru many threads about the D2 hubs for a trailer, I decided to be safe and use Melbourne trailers.
They were great, easy to deal with , can get the hubs to suit D2 with 14mm studs, no problems. They had it listed on their landy list of hubs.

They arrived, and damn they dont fit the alloys due to the bearing hub/cap not fitting into the alloy.

These are non braked hubs, so they must be using different hubs now that are larger, or just have more meat in them.

Just thought I'd put this up, as its still not a definte fit with the alloys.

I dont want to grind out the alloys, so might start looking for some steel rims instead.

The alloys have a two stepped 'hole' for the bearing/hub cap. Steel is 70mm (just measured it) them same as the first or larger step of the alloy.

I have the wheels but still haven't got hubs organised yet. How much did the hubs cost you?

Also what axle do they fit?
