Last time I trailered my Montauk a few hours, I noticed one bearing was warm to the touch. While it was not hot, it definately was warm - is this a sign of a problem?

Heat will kill a bearing in no time...

But, if you can touch the bearing cap/hub for any length of time, I would not worry too much. Often, a warm bearing is a sign of too much grease. Usually, the excess grease will leak out and then the temp will return to normal.

Here in the Northern California interior the air temp is often 100-110 degrees in the shade. If you touch your hub it always feels warm. I have noticed when I go to the coast my hubs feel a lot cooler. I think that the outside tempature is a factor to be considered when checking your hubs.

What do others thinks?

If it is hot outside, feel your tires then feel the hubs.

If the hubs feel warmer than the tires, check the bearings.

You may had been lucky and caught a bad bearing before it left you on the side of the road.

If you have a jack, lift the axle and with your hands on the top of the tire, shake the tire to check for too much "play". (axle nut too loose)

If you just changed the bearings and the hub is too warm, you may have torqued the axle nut too much.(too much friction)

Pull the cap and cotter pin and re-torque.

Often when on the road and hauling a trailer, one side of the trailer will be in direct sun while the other is in shade (from the boat). It is my experience that the bearings and tires on the sunny side are always warmer to the touch than the ones on the shaded side.
