[Wave monkey]

Have a vibration noise sounds only can hear at idle in gear or neutral 1324 hrs computer says everything's good from dealer I can hear sound like whining belt idler pulley can feel roughness while running on muffs on outside of leg had lower unit checked came up good I came up with the driveshaft bushing in the drive shaft housing is there a bearing at top of shaft that could be making this noise

It might help many of us if you can tell us a little more than a vibration and noises? Our ability to read minds is on the Fritz, and our crystal balls have bad batteries this week. Hope to have both back in operation in a month or two.

Seriously a little more info could help.
