Alko hub stub axle

[Johno99]

Hi, I’ve recently bought a Bombard 500 and I’ve been refurbishing the Extreme trailer, rollers in the wrong places and seized, bolts and u bolts badly corroded, all replaced in stainless. Anyway the hubs have got tapered bearings, which I prefer, and I’ve managed to get new bearings and going to replace tomorrow. One of the stub axles has slight damage and looks like someone has whacked it. I enquired to Extreme trailers and they have told me that the whole axle will need replacing. I’m sure I can repair the damage but surely this cannot be right can it? So if you damage the treads it’s going to cost many hundreds of pounds to get around plus actually doing the job and scrap an axle! Madness.

These days a lot of stub axles are welded.


Some of the older Alko axles had a bolted stub axle, with a single 22mm allen Bolt on the rear and flanged on the hub side.


I guess you could change a welded stub, but it would be a lot of work, and you would need to make a jig for the alignment before welding in the new stub.

Thanks Gpsguru,
Having a closer look I agree that the whole axle is one piece and the only way out would be to weld on a new stub to replace a damaged one. I’d have to find one, remove the axle, remove the stub, use a jig and weld the new stub on. Not going to happen in reality.
A replacement axle from Extreme could be over £800 depending on the size. Madness just for a few damaged threads. Anyway thank you. Just having a moan really. John

there are other options for a replacement axle, can’t remember the name of the company but I’m sure someone will be along soon with the name, you just give them the measurements and they will build it to your specifications, including taper bearings

If its just a few damaged threads can you use a thread chaser? Example here https://www.amazon.co.uk/Thread-Rest.../dp/B09BVVY4HN
Or buy a die nut the right size & thread?


Google Thread repair stub axle brings up all manner of possibilities.

Thanks everyone. I seem to have gotten around the problem carefully with a junior hacksaw and the nut is running along away. Luckily it’s held with a new split pin. As I said before I’m just having a moan really. I will look at Peak Dynamics, hopefully I won’t need them.

That's what I'd be trying before buying a new axle.

Extreme are well known for being expensive with replacement axles, however, their trailers are generally pretty good.

An Alko unbraked galved axle retails at about £250, and and a fully galved 1500kg Alko axle retails at £600 (ish), but there are also cheaper options.

If my 1500kg Knott axle needs replacing, then I will go with an aluminium axle, also cheaper than the alko or knott
