I put on new tires this year and found that one of the hubs needs to have the bearing replaced - a second one should be done also (I have a dual axle). This is my first year with the camper so I was somewhat surprised to see that the wheels have bolts and not stubs like a car - what a PAIN that is! So while I'm looking at doing the bearings I ran across replacement hubs that have studs and they're only a little more expensive than buying the bearings and caps - I'm looking at about $25 each (http://www.etrailer.com/Trailer-Hubs...r/34822BX.html
). So my question is, has anyone every replaced their hubs with new ones? I'm not sure if it's worth it but I think all it would take is one dark night on the side of the road replacing a tire to convince me...
