Donny,
I have the same "hum" on my R/T CC. Im not real interested in letting my
dealers "minions" drive my truck @ 90+mph to road test my complaint. Luckily
it is it has gotten better over time and seems to start at a higher speed
now (moving up from 80 to 90 mph) and goes away at around 105 mph. The
alignment shop thought it might be the tires. they found a flat spot on my
right front (that goodyear says is "normal"...Im not so sure about it being
the tires, and I always though a tires normal condition was round... Im
going to wait and see what happens for a few thousand miles. If it doesnt
go away, then Ill get together with the dealer...
BKB

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,
