Vibration when towing?

[Lima-18]

I have an 01 F-350 that I bought new. I recently noticed a vibration when towing (light load). I have changed trailers and the vibration is still there. The vibration is not there when I don't have a trailer connected. Does any one have similar issues or does anyone have any ideas what might be causing the vibration? Thanks in advance for any insight.

The vibration is like an intermittent hum that is present during all operations. It is more noticeable at higher speeds and can be felt throughout the whole truck. Its like the lines in the road letting you know a stop sign is ahead.

Check to see if any part of your receiver is loose.

Great place to start. Thank you

Check anything in that drive line that moves. When you tow depending on your load, you are changing the ride height of the truck. The pinion angle will change a bit and so on. Look at U joints, carrier bearings, anything like that.

Thank you Galaxie! Turned out that my carrier bearing was going bad. I just got around to replacing it and pulling a trailer. Great info. Thanks again

How do you like the MBRP exhaust? Like I said my truck is a 2001 7.3 f-350 crew cab long bed. I am thinking about changing out the stock exhaust. Any suggestions?

Glad to hear you fixed it! Ya, with a 7.3, as long as you remove that muffler it will sound sweet! I have the MBRP on my 6.0. I like it.
