Bearing Temps

[MNRon]

I just repacked bearings and replaced all seals last weekend. Today was first day towing again. It's gorgeous up in the UP!!! Beautiful fall colors and temp is still 70 at 10pm. Back to my question.

I measured the temp of the hubs with an IR monitor when we pulled in after pulling 350miles today. Both front trailer tire hubs were ~105degF, while both rear tire hubs were 125-130degF. I suspect it's loading as there's 50gal of water ~5' aft of the rear axle. Should I be concerned for the bearings? I don't think I overtightened them, bet didn't expect to see that much temp variance. This is the first time I've checked temps so I don't have a reference.

Thanks in advance for any comments.

Do you have 4 wheel brakes on the trailer?

Those were our hub temps on a hot (90-degree) day recently, after a bearing repack. In cooler (60s/70s) weather our hub temps were 95-105. Tire temps were fairly similar, but of course warmer on the sunny side of the TT.

Bet if you went across a set of scales (loaded as you were) you will find a big difference in axle weights on trailer.

I've seen those temps but not on a cool day.

Check your brake adjustments also

what was the tire temps? on my mh the rear tires on my tag also run at a higher temp then the drive. and that will make the hubs run warmer, also not as much air for cooling the rear tire & hub.
