People misunderstand mechanical maintenance. They see a part still in working condition but prematurely due for replacement, and hesitate to change it before it actually fails. This approach may seem sound in theory, but the maths simply don’t work out that way in real life, and the full picture usually includes a lot of money.
It is cheap and simple to change a wheel bearing when it turns rough-running due to wear. It is also very costly to wait until the bearing actually fails in use, at speed, especially with hub damage and possible damage to the stub axle as a result. The scored and normally serviceable bearing is merely collateral damage from the initial failure, but that damage is a direct result of the preventative maintenance failure to change the bearing before it failed.

The same is true for any component of the trailer, including but not limited to brake components, couplings and especially tyres. The cost of replacing a worn part late, including the part itself, the damage caused by the failure and the cost of recovery, road use and repair, is simply not justified by any kind of logic.
And of course, one must not overlook the safety part in this financial calculation.
The prospect of a bearing failing at seventy miles an hour on a motorway is expensive, but far more than that, it is simply dangerous. Maintenance cost cannot be measured against that.
The worn part should always be replaced early, because that is the cheapest version of the problem. Every delay in doing so makes it more expensive and serious.
