It's audible and you can feel it too? From the front or back? If you
can hear it then it may be axle or wheel bearings.
If it's just a vibration put it in neutral and if it's there it could be
your wheels or driveshaft being out of balance.

Hi All,
Just a quick question--mainly to the other RT owners,
but may apply to all.
I have noticed a strange HUM (drone, vibration, ????)
from my RT at high
speeds. It normally starts about 85-90 and gets fairly
bad by 100+. What
could be causing this? I don't have any other strange
vibrations at any
other speed or RPM level. Could it be tires?
Alignment? Slightly out of
balance drive shaft? How do I explain to the dealer
that my truck seems to
hum at 100 mph?
Thanks,
Donny M Hayes
