Trailer axle knock

[wickedinhere]

Today i was checking my tire pressure on my trailer and i pushed on the tire with my foot and the axle made a knocking sound. I was wondering if this could be
a sign of bearing failure its about 3 years old i have never greased the bearings
but there not making any noise. I will jack it up tomorrow and see whats goin on
any suggestions?

I'm sure that you already know that we a little more info than that

Tell me what you need.

Bearings somewhat snug? how much end play when you wiggle top of tire and does it make a noise when you spin wheel ? for starters , does it spin freely? without weird noises

I got it jacked up and checked the rear axle. Both tires spin easily with no niose
and both of them do have some play when i try to wiggle them but not very much. I was thinking maybe the axle nut is slightly loose? I not sure how often your suppose to repack the wheel bearings.

The easily and no noise is a good thing
and the re-pack bearings will come up with a search unless someone else comes up with it, I wish you were here, we could do this in minutes

Thanks for the help, i have changed and repacked bearings before so hopefully it will go easily. I am gonna do the back axle tomorrow and if it goes pretty easy i will do the front axle also. Thanks again for the quick response and help i will update you tomorrow and let you know how it went.

Axles are easy, no top play and good smooth sound when ya spin them, any grinding sounds are not good at all

It's not unusual for a little play after the grease from a previous packing job has basically run out of the bearings but still there....make sense...

I think most of the "experts" recommend annually, but I doubt that anyone actually does that. If there's very much "play" at all, I'd do it, though. It's not a difficult job; just messy.
