#How often to repack trailer bearings free#

Make sure the the seal face on the hub is free of pits and rust, a pice of emery and a bit of elbow grease is all this needs. The only thing to keep I'm mind is when fitting these preparation is the key. Locktite on the edge of the seal and on the insert face of the dura hub.

I do dunk my bearings every launch and have had the same set of bearings running on my trailer for six years and they are as quiet as the day I fitted them. I now check my bearings every trip visually and every six months physically , I fitted quality Japanese bearings which usually only cost around five dollars more than the cheapies. They have a clear window in the front face that allows visual inspection to see if the seals have failed and allowed water to enter the hub. They are filled with oil rather than grease. I was in the same situation, checking bearings all of the time ,changing yearly, occasionally finding a grinder - change out. If you overload or underload them - you don't get this effect and maybe thats why some people are having mixed results with them. The bearing budies have a spring loaded plate, and if correctly loaded with grease this plate allows for expansion and contraction of the internal hub contents.

Also as you drive, bearings and hubs warm up, any air in the hub expands - when the hubs hit the cold water this air contracts and can suck in water if your hub seals are compromised. they keep positive grease pressure on the bearing and deter water ingress. You must keep them correctly filled with grease and CHECK the back seal on the hub.the problems usually occur from the back seal. Anyway, bearing buddies are NOT maintenance free. My 2nd trailer came fitted with the plastic type and after a 100km run I found one of the plastic ones had popped off - cheap rubbish. Personally I always fit the more expensive stainless type - they are far more durable. Based on my experience I swear by Bearing buddies.
