General Zod Posted June 1, 2012 Share Posted June 1, 2012 (edited) Hi, just want to know when I need to replace my trailer bearings. I took the wheel off and spun the axle around and it seems smooth. The grease still looks new. This is only from the front though. Haven't taken of everything yet. Are there any signs of when I might need to replace the bearings, like any noise when I'm driving etc. Any help would be appreciated.

Catchin Jack Posted June 1, 2012 Share Posted June 1, 2012 Personally I do mine yearly regardless of how they are, gives me something to do over winter. Link to comment Share on other sites More sharing options...
The Incredible Hull Posted June 1, 2012 Share Posted June 1, 2012 From what others have experience and told me, I think you hear it before it goes. Apparently it gives you plenty of warning. I remember a raider telling me he drove his trailer around for a number of sessions with a loud screeching noise (i.e. no grease). Link to comment Share on other sites More sharing options...
austral Posted June 1, 2012 Share Posted June 1, 2012 it depends on how far you tow your trailer, if the ramp is only around the corner then every couple of years should be ok. but if your driving a fair way or regularly take long trips away then every year is advisable..

BFB Posted June 1, 2012 Share Posted June 1, 2012 Bearings will not always give a sign before they go. I would heck and re-pack them every year. It does not take too much time but gives great peace of mind. It is one of the worst jobs in the world to change wheel bearings on the side of the road especially if it is at night and raining.

mr magoo Posted June 1, 2012 Share Posted June 1, 2012 i used to inspect my bearings yearly and change them if there was freeplay or water intrusion in the grease ,i got caught out one day doin it a hundred klms from home ,so i replace them yearly now,and i keep a hub packed with a greased bearing in the car just incase but in saying that i once got 5 yrs out of a set of bearings(single axle)but i lived two minutes from the ramp,i now live 30 minutes from the ramp and its a duel axle set up witch i beleive place more load on the bearing when turning Link to comment Share on other sites More sharing options...
Juggs Posted June 1, 2012 Share Posted June 1, 2012 I do it every 4 4l bottles of 2 stroke oil When I buy a box of four bottles I buy a set of bearings Weird but works for me if I use it more it means I check them more replace them more often Sometimes it's every 6 months By the time you have heard the grinding noise it's highly likely you have scoured the stub axle which if not cleaned up or replaced you will shorten the life of the new set 20k of boat is reliant on $60 worth of bearings Apart from the inconvienenace of breaking down and not getting out Its not worth losing it at speed and destroying the boat or killing someone Link to comment Share on other sites More sharing options...
pjbink Posted June 2, 2012 Share Posted June 2, 2012 They can last a long time if you don't dunk them underwater when launching / retrieving. Ie, 6 years plus. Link to comment Share on other sites More sharing options...
dogbox Posted June 2, 2012 Share Posted June 2, 2012 Wheel bearings on your boat trailer should be checked annually by jacking up the trailer, spinning the wheel listening for noise, holding the tyre and testing for excessive movement that suggests bearing wear near collapse. If in doubt replace your bearings. Dogbox Link to comment Share on other sites More sharing options...
