An axle-and-hub assembly for a trailer, the axle-and-hub assembly including:
an axle having opposing ends;
a first connecting flange and a second connecting flange positioned at the opposing ends of the axle, respectively;
a first hub arrangement having a first plate that is directly and removably secured to the first connecting flange;
a second hub arrangement having a second plate that is directly and removably secured to the second connecting flange; and
a shock absorbing arrangement between the first and second hub arrangements,
wherein the first plate and the first connecting flange are formed with respective recesses which are in register with each other and which allow for the passage of a first rod which is connected to the first hub arrangement and the shock absorbing arrangement, and
wherein the second plate and the second connecting flange are formed with respective recesses which are in register with each other and which allow for the passage of a second rod which is connected to the second hub arrangement and the shock absorbing arrangement.

### Claim 2 (depends on 1)
