Ok so... I'm building an L405 Trailer, I have 8 20" wheels (L405) and I am struggling to find out what stub axxle I need to be able to use my 20" wheels... I know they are roughly 5x112 etc. But I can't seem to find stub axles to fit these wheels.. can any one help? Maybe I am searching for the wrong thing?

I am building it with air suspension and independent trailing arm suspension with it's own onboard battery, charged by a 13 pin caravan plug, this will also power the compressor and leveling valves for the trailer..

Appreciate any help

I should add it's unbraked single axle

I think all RR wheels are 5x120 PCD 2017 4.4 SDV8 Autobiography

Yes you are correct.. mobile phone type O PCD 120..

My only options I think are a 4x100 stub axle and an adapter... but I'd prefer it to be a stub axle that is already 5x 120

You might have a bit more luck at a 5 stud axle from someone that supplies agricultural trailer parts. The ones I’ve seen all seem to be 5 or 6 stud. 2017 4.4 SDV8 Autobiography

Not be simpler using a rear axle setup from a td5 discovery (or P38 RR ) ? ... would be the same PCD for the wheels, track width etc. already compatible for air springs as they were a fitment to that vehicle ( as was the P38 ) so parts readily available.

Strip the diff and halfshafts out, calipers off etc, weight wouldn't be that bad. They go on ebay for around £150 ...

Realistically through ... unbraked ? thats going to limit you significantly weight wise surely ? a total limit of 750kg for the trailer would mean that self levelling would almost be hardly worth the complication. Your 4 wheels alone will rack up to almost 150kg, the trailer frame and body likely another 200kg (if not more )... so your already down for a load capacity of 400kg. How much is that really going to deflect the suspension such that you need levelling ... would springs not be easier, and reduce complication ? V8 or else ...

Stub axle?

Or hub?



Here in Oz, the 5 x 120 is as common as muck and easily purchased from any trailer supplier, auto parts supplier, or eBay. It's probably the most common trailer hub down here close followed by a Ford 5 stud pattern. You will need to match the bearings to the stub axle. Here, there are two groups - Holden bearings or Ford bearings (different sizes). That may apply up there. Have a look at the UK AL-KO catalogue. There may be something there. There certainly is in the Oz version of their catalogue.

It was/is used on a number of GM cars, e.g., the Holden Commodore. Maybe the Opel Commodore or some Vauxhalls use the same PCD Ron B. VK2OTC

VW transporter rear end may be worth a look, they have the same stud pattern

Or just use some adapters, theres many variants availabe.


I do agree with the 750kg weight issue though, you aren't going to have a huge capacity if you want to legally carry much more than a couple of hundred kilograms Current

I was watching the Guy Martin Nürburgring episode and I'm sure he had RR wheels on the rear of his Transit. Transit hubs might be an option. See pic here:

Rear hubs on Guy’s transit were not ford items.

There is a fellow building Volkswagen transporter alike trailers who may sell suspension units with the right pcd?

Bill Blackmore was his name I think, google might be a way to locate him?

Aha! I've not taken much notice of Transits since I sold mine back in the 70s. Ron B. VK2OTC

Must admit they are not my choice, but the pcd on transit wheels seems huge.
My involvement with transits ended in 90’s when I moved on from my first employer.
