'91 LS400 Hums under NO load
My apologies if this has been answered. I found a ton of posts about drive-train vibrations and noises under load, but I have the opposite problem.
When I back off the accelerator at freeway speeds, I get a deep-pitched humming noise. Almost like wind noise through a door seal or an exhaust note. From the driver's seat it sounds like it's coming from the rear passenger-side door. From the passenger seat I'm told it sounds like it's coming from the left side of the car.
And it's just a hum. No vibrations or anything like that. And the pitch doesn't seem to change with speed.
Any suggestions?
Thanks in advance!
