Thread: Six wheel studs to five wheel studs - why is it so hard?

I had similar issue and ended up ditching the LC compatible axle and 6 stud hubs altogether. As I was building a camper (simple frame- Navara tub/ARB canopy,roof top tent etc) the weight was not an issue. Fitted 45mm round axle with 10" off road "Commodore" Alko hubs, "outback" heavy duty magnets for electric brakes, slimline (Ford) bearings.

Got hubs drilled with Commodore VE PCD and pressed in 14mm wheel studs obtained from Holden dealer. Thickness of the hubs is a lot less than the standard Commodore disc rotor and therefore, 9mm wheel spacers are needed to pad out studs with alloy wheels otherwise studs are too long to accept standard D2/P38a wheel nuts.

Did not want to cut the studs...besides which there's not enough threaded section to properly torque up the nuts unless the wheel spacers are used (about $20 from Autobarn). Hope this is of some use....

BTW, the machined length on each end of the axle, dictated by the size of the bearings, precluded any need to enlarge the spigot hole in the alloy rims...

I'm on my phone at the minute, so I'll reply in depth later

Just thought I should point out that the alloys won't even fit over the Holden/Ford (LM/SM bearings) hubs as they fowl on the bit the centre caps clip into, so spacers are needed (they are illegal iirc), no machining of the alloys should take place, they go over the bearing 'housings' (for want of a better word), however they don't locate so a collar must be made up, machined and fitted to locate the alloys on, this however is not needed for steel wheels as they locate on the studs.

Also as mentioned above the hubs that's use te larger bearings (same inner and outer) fit RRS wheels (we did a Kimberly a while), not sure about D2 off the top of my head. However any hub needs a flat (round, not tapered) surface turned on it to either fit a collar or act as the spigot itself.

Incidentally I fitted D2 steel wheels to my trailer today (unbraked as its only for a dune buggy). Not a hard job at all.

Mat can you tell me what type of bearings the caravan runs, it may be a very simple job (HQ brake drums as drilled out to fit the bigger studs).

Oh and to answer your question, it is cos it is a land ro ver, they are weird (one syllable for ya haha)

Would that be the SLM (same bearing OD) or TF9 (same bearings) bearing configuration? Are 12" electric brakes available?

I'm not sure, all the details are on the Alko website, just don't have time to look right now, the axle bearing surface is parallel and they have the same I.D and O.D (so its inner bearings all round). Alko will tell you if the hubs are available, I'd advise ordering through a trailer store, (we get ours from Classic trailers as dad knows the fella)

Don't know where you got your information... I actually built mine ...no machining of hubs, enough clearance to clip in the wheel centres if needed... wheels centre themselves on the studs as they do on the P38.
9 mm wheel spacers are not illegal on a trailer....

Sorry Hoges, I was referring to when the spacers aren't fitted. I know for a fact that the alloys don't fit over an I brakes hub without spacers, however all our conversions with brakes had spacers anyway so they fitted like yours.

I'm very glad to hear the spacers aren't illegal thanks

However I'll pull you up on the wheel locating part, LR alloys (expect freelander 2 (maybe 1 aswell, never been near them though)) locate on a centre spigot, the nuts only hold them on and transfer the torque. The holes are parallel drilled the whole way through to the width of the shank on the nuts. The taper is for cars with a steel spare. As a result when the nuts aren't tight they eventually get balance issues and can break studs. I would recommend getting centre spigots made up to locate your wheels properly

Also I think I might have quoted the wrong post haha, can't remember now, was the one about bearings and fitting I think. So wasn't a dig at your trailer

The trailer is UGLY...but it does the job!!

I had a look at an Alko parallel bearing 1.5T hub today. I'd be surprised if it can't be machined sufficiently to allow fitment of LR 5-stud 120mm pcd alloy rims which is likely what was done to fit RRS rims. The hub can take 12" drums so plenty of braking capacity for larger diameter tyres. I've emailed Alko for comment/confirmation. Vehicle Components' equivalent hub is rated for 2T but its spigot is far too big for LR rims.

Yes that's exactly what we did!! there is so much meat there it's not even funny anyway.
