When to replace sealed for life bearings?

As per title...

Trailer is now 9 months old and has been dunked quite a few times in salt and then immediately rinsed with hub flush kit.

Should I replace them over winter?

Are these Alkos?

I can't know what shape yours are in but I ran a set over three seasons and the bearings seemed fine when I sold up. If you have let the hubs cool before launching and not otherwise abused them, I'd give the wheel a rattle and see if there is any give or rolling rumble....

My 2d worth........If you have a single axle trailer and you ever hit a decent sustained speed with it , is it worth the risk not to ?

Bearings by definition must be kept in A1 condition . The moment they start to deteriorate things can only go downhill very quickly and you can write off an axle , maybe damage the rib and cause an accident . I know that's the worse case scenario but if it were to happen it can be scary and will definitely be inconvenient and costly .

I change my Alko bearings every year ( and still give them a quick check before any long run ) . They always look ok as I discard 'em but once bitten twice shy for me .

I have Alco sealed Bearings cooled...(mostly) before dunking 5 seasons thousands of miles...changed one this year more of a precaution than anything..check for noise/rumbles and heat on a regular basis and they should be good for sometime

First couple of years with Alko bearings & I changed them annually, out of habit. I realised I was chucking away 60 quids worth of perfickerly good kit. I still had to do the brakes annually & checked the bearings at the same time.

Thanks gents, I'll take the hub off anyway to inspect the brakes as a matter of course.

I have REALLY babbied them and rinsed immediately after salt every time so I'm curious to see how much the hub flush really does.

One thing, the nut on them is a one time use?

I've had mine 3 years but don't dunk them in the salty stuff. I just jack the trailer up & give the wheels a spin, if it's all quiet and smooth that'll do for me. I also feel them when I've done a few miles on a journey and they've never felt any more than barely warm. I still think the 'old' style greasable bearings are preferable to these for anybody that likes to maintain stuff.

According to Alko then yes one time use only .

( I have taken liberties here with no disasters up until now . I 'd probably tighten them that little bit extra " second time around " )
