No what I am saying is that negligence of maintenance is the default stance taken, and that proving that negligence has not occurred in the case of tyre blowouts is extremely difficult for a layman, I would assume the situation would be the same in the event of a bearing failure.
The owner of the tyre has to prove nothing. The injured party who is looking to claim has to do the proving.

Asking on behalf of a mate...my wheels haven't fallen off!!

Yesterday on the way home from a drifting event, my friend's trailer wheel fell off, bounced down the road and was brought to a sudden halt by another motorist. The wheel bearing failed. Castle nut and split pin left on the hub along with the inner race and bearing parts, brake drum and wheel nuts still on the wheel and the brake internals scattered and destroyed. Photo evidence of this was taken.

All four trailer wheel bearings were replaced at once, two months ago, and the trailer has only had two outings since. Regardless of who fitted bearings (I think my mate did them himself - they aren't exactly a specialist job), who should take the blame. Insurance details have been exchanged, but I think blame (and therefore the damaged motorist's costs plus repairs) should fall to the bearing supplier or manufacturer. Any advice on how to proceed? I have advised him to use tact and diplomacy, but should he contact his insurers first thing in the morning, or wait out for the suppliers?
You are friggin kidding right? Seriously nobody can be this arrogant can they?

The only way it would be the bearing companies fault is:

-if you could prove that the accident was 100% due to a fault with their bearing.

Something you'll never be able to do.

And even then, you'd likely need to prove negligence on their behalf for knowling selling a bearing that could cause such an accident.

And even then, it'd still be just an 'accident'.

Not true.

If he could prove it was 100% due to a faulty bearing, he wouldn't have to show they knowingly sold it as faulty. He wouldn't have to do anything, other than tell the tp that the bearing was faulty and therefore deny any liability on his part. If would then be for the tp to deal with the bearing supplier.

Even if the bearing was faulty, it would be near impossible to prove it was the sole and only cause of such an accident. So I don't think it's really an issue to solve.

Hmmm, that'd be something to see!

I'd bet that most, if not all, bearing manufacturers would be able to justify their manufacturing process a lot better than the OP's mate could prove he'd fitted the bearing properly.

I'd also bet the failure was because they'd been overtightened when fitted which will likely be the manufacturer's stance and very hard to disprove. It's so easily done if you don't know what you're doing.

I don't disagree with any of that. But it was being claimed that if you could prove the bearing was faulty, the trailer owner would still have to do this and that. He wouldn't.

If you have the pieces then a decent metallographic investigation should be able to determine cause or at least the initiation point certain failure modes would be entirely within the part, other could be influenced by the fitting. Expect to pay north of £500.

injured party claims from your mates insurance - mate takes it up with either his insurance or bearing manufacturer or both , gets the runaround from both then concedes defeat

this is what will happen

I wonder how far into the process the OP's mates insurer will get before they start asking questions about the trailer spec/drift car make and comparing those numbers to the car they are insuring to tow it with............very easy to fall foul of the weights

Apologies for derailing this slightly, but I tow regularly and have told my insurers about the towbar on the car. In this instance would the car insurance cover the damage to the other vehicle, or should dedicated trailer insurance be in place?

I have checked my insurance documents which say

All UK policies by law have to provide tp cover for towing. So tp injury or tp property damage caused by something you are towing would be covered (providing, like any claim against you you are negligent).

What kind of failure mode couldn't be influenced by incorrect fitment?

I'm struggling to understand the failure mode if it is a taper bearing.

If you over or under tighten them they will fail quickly, but they will not detach from the stub axle because you can't actually fit the stub over the castle nut, let alone the washer under the nut. Is the big washer still there? If it is, then something very odd has happened - you could asssemble the thing with no bearing at all, it would run like crap, but it would stay on.

If he left the washer out, and the design has a tiny castle nut .... maybe.

Incorrect size / quantity of balls / rollers?
Non-metallic inclusion in the housing resulting in a fracture?

This is what I meant. In both those examples failure would be accelerated by incorrect fitment.

I assume you meant that the hub won't come over the castellated nut? I thought this but I'm not so sure; I think there are designs where, if you lost all the rollers, the outer races and therefore the hub would come over the inner face and the nut/thrust washer.

I'm with RXE, I don't think I've ever seen a wheel on a trailer where the bearing could come of over the washer and nut no matter what happened. Need to go and have a close look at mine, but I would very much like a photo of this trailer cos I think this isn't possible if put together correctly

Yes, I meant get the hub over the nut. The only vehicles I have with taper bearings are an Alfetta GTV and a couple of land-rovers, none of these could fit the hub over an installed nut and washer.
