Trailer vibration.....causes?

[honyack]

Anyone have any experience on what would be causing the side rails of the trailer to be vibrating excessively when pulled > 55 mph? Just started happening this wknd...??

Wheel bearings. Jack up each tire and spin. Noise indicates the culprit. If you can't hear anything, grab the top and bottom of the tire and alternate a shaking motion. There should be NO movement there either, it should be solid and not rock around. Get it fixed ASAP as I've had to replace axels because customers let it go and it screwed up the spindles. Good luck.

Wheel balance?

I'll check the bearings......thanks for the heads up!! Kind of weird b/c last weekend everything was fine and then all of a sudden the next week its out of whack. I'll get it checked out.

- Maybe a steel belt in one of the tires?

- inside of wheel may have mud/sand caked on and dried?
