slight vibration on acceleration
I just picked up my new (to me) '05 RL with 33k miles on it this week. Looooooove it. It is replacing my '97 3.2TL that was totaled.
I have gone through all the "known problems/quirks" posts and watched my intro DVD and read the phone book sized manual. So generally I am pretty up to speed but still finding treats each day.
My question and I do have one.....
I feel a slight vibration when I accelerate. It's not the motor because it doesn't happen when I rev in neutral, even if rolling.
I saw that there was a post about a grinding but that seems much more severe, performance loss etc.
There are no other symptoms. Motor pulls hard, all systems seem fine.
So is this just a quality of the drivetrain or is there something wrong?
Thanks,
Adam

Are you feeling the vibration around 1500rpms? This would be under light acceleration. You would feel it through the steering wheel and possibly the accelerator pedal.
If so, that's considered normal for this car. Considering it's all wheel drive, I'll cut it some slack

It is light and I do feel it from several points. But it seems to be across a wide RPM range. Maybe I should go "test drive" some others and see if is the same.
How do I get the drive shaft bearings checked out? Just ask a dealer to take a look? I assume that is in my 4 year warranty, which is up next year.

Here is some info on the bearing problem from the May 2008 Acura Service News. See the sticky at the top of the 2G RL Forum.
From this, it sounds as if it is not the propellor shaft, and if it is, it is not yet very bad, i.e., no howling or squealing noise.
You can search the site for more info using google and the search term
site://rl.acurazine.com
plus a search term like "propellor shaft" or whatever
Whine, Whistle, or Howl
Between 30 and 40 MPH
Currently Applies To: ’05–08 RL
A bad propeller shaft center support bearing can
cause an annoying whine, whistle, or howl if you’re
driving between 30 and 40 mph and the bearing is
cold.
To check for a bad center support bearing, here’s
what you need to do:
1. Raise the vehicle on a lift, and make sure that it’s
securely supported.
2. Have someone start the engine, shift into Drive,
and slowly accelerate until the speedometer
reads between 30 and 40 mph.
3. While standing under the center support bearing,
use a stethoscope to listen for noise coming from
the bearing.
• If you hear noise coming from the bearing,
replace the propeller shaft. Refer to pages
16-42 thru 16-45 of the ’05–08 RL S/M.
(Online, enter keyword PROPELLER and
select Propeller Shaft Removal and
Propeller Shaft Installation from the list.)
• If the bearing is quiet, continue with normal
troubleshooting
