(Un)lucky Day!

Overnight I pulled the RIB from Somerset, through Glasgow, and to Campbeltown, stopped twice on the way for fuel etc, checked wheels and hubs each time, no real heat etc, all seemed fine. Last stop was just after Glasgow.

We finally got to our destination, and as we went through the gate to the causeway to the Island, one of the wheels of the trailer fell off!

It was very hot, sizzling noisily in the wet grass, so I guess the bearing had failed!

As we did not have too long to get across, we crawled over on 3 wheels!

Of course I had no spare hub, so will order 2 complete hubs!

Luckily we are here for at least 3 weeks, so we will launch as is, put the boat on the mooring and fix it.
Also pointed out was as though it was unlucky to have failed, at least it did so only a mile from the destination, and all off road.

Note to oneself, Always carry a spare hub!

Why not replace all four (4) hubs?

I had a brake shoe fail (most likely due to rust), and the entire bearing, after smoking a lot, burst into flame. A fire extinguisher and lot of water bottles later, it was towed to a place that replaced everything on the left side, and shoes on the right.

Not exactly an ideal trip.

Glad you made it with as little problem as you did.

I think you were lucky. Did you tow it across the causeway to Davaar?

Check your shoes and cables too.

The most common reason for the brakes cooking, ergo dispersing any grease and making the bearing fail, is due to the brakes seizing / dragging. And the most common reason for that is seized cables.

Check that the shoes are ok too, and not delaminating, as the linings are only glued on nowadays and often the heat cooks the glue off.

If you've still got the drum then you shouldn't need a new one. Just clean up the inside face and fit new bearings and you should be fine.

The aft axle was added last year for just such an incident, bought it brand new, so I am happy with them. I will probably renew both, and keep the old hub/bearings as an emergency spare.

Poly, yes I did, we are staying here for a while, lovely place, we have a mooring, and jetty to use here, although the jetty is only a couple of hours either side of HW

Thanks for the advice, will do once I get the boat on the mooring.

I didnt think I can change the bearings, the axle is by peak, and when I ordered the axle last year I had asked for a spare set of bearings, and they told me that they were not replaceable.

Sounds like an excellent reason not to buy stuff by Peak!
Are they saying you need to buy a complete hub/brake drum assembly?
I'd have a look at the bearings to see what numbers are on them, then see if a decent bearing supplier can sort you out.

Its one of the plus sides of twin axle trailers. Many years ago we bought a brand new caravan. On its inaugural run we were heading south on the M1. I noticed that a number of people were passing us & pointing downwards. A quick stop on the hard shoulder revealed a completely shredded tyre. I had no idea when it happened as there was no change in the caravan. Pulled off at the next off slip & changed the wheel.
