Trailer woes...

Exactly this !

Hardly an expensive manufacturing consideration, for the road safety benefit.

If this regularly happened to a make of car or truck -we'd all know about it and the manufacturers would soon sort it out !

I guess maybe I'm just too used to wearing seat belts and that 'safety' mindset..

🤔

It wouldn't work as the shaft rotates within the tube and the rubber inserts stop it turning but acts like a very low tech shock absorber, think pinching your finger in a door jam.

 

To make it work the shaft would need to be longer than the tube with an exposed end to allow for the tab.

 

Personally I'd never have a single axle trailer with rubber suspension, seen the rubber fall apart.

 

As Jase suggested solid axle like an old Sankey.

Agreed. Then that would mean springs. 

 

Mine were plenty bouncy enough empty just on the rubber. Put springs on it? 

At least the Sankey had some weight in them by virtue of their construction.

Whilst not a bad idea in itself, a trailer in that weight class is what 120kg empty and I'm not sure of the vosa position if you got pulled.

 

If it was me and that had happened to the same trailer more than once I would be skipping it entirely and buying something else.

Not really as the square tube could have a slot into  which a set screw could locate, the slot allowing the square to articulated in the tube.

 

How are these things put together and what currently holds the square shaft into the tube, I cannot believe it is just friction?

So out of the many millions of trailers, you want to redesign a cheap trailer.

 

And adding a slot & set screw is simpler than just making the shaft longer and a bolt and washer on the end?.

 

Either way, skip it and buy something that's better than a Halfords special.
