Good luck. :shades:
I will really appreciate an advice.
For the first time, I put the rear passenger windows down while driving and when the windows get about 1/4 of the way down, a horrible and unnerving, low frequency resonance vibration caused by the airflow around the cab started. The way I can describe it is if you've ever heard or seen on TV a show on the new non-lethal weapons the military is designing, they have one weapon that emits low freq vibrations that makes the target sick and very uncomfortable. This sound is what I think that weapon sounds like. It was a "whoop-whoop-whoop" sound w/ about 3-4 whoops per sec. The vibration was not only felt but hear and it hurt my ears and body because it had a very low freq, kind of like when those kids ride by in their cars w/ the pimped out bass woofers that you can feel in your chest and hear from a mile away. The front passenger seatback was vibrating so much that the headrest was moving back and forth about 1/4 in. I was doing 60 mph and tried putting down both windows, then each one individually and it still occurred. It starts about 1/4 of the way down and seemed to soften lighty (but still there) when completely down. It was loudest at about midway. I thought for sure I had the rear windows down before and never noticed. The only thing that may have changed the airflow that I can think of was that I had 4 small 80# bags of concrete in the bed, nothing that I think would cause major disruptions in the slipstream.
I can't believe that this would be a major oversight/design flaw that Toyota let go so I was wondering if anyone else noticed the same problem?
I went to a reputable glass place and had the windshield replaced.
What I noticed after replacement was a high pitched noise (which sounds like a teapot coming to boil) at
speeds between 30-45 MPH. I took the jeep back a week later
and they replaced the windshield again.
The results were the same only the speeds at which they occurred was 40-60 mph.
As you know the windshield has no molding. Has anyone experienced this and found a reasonable solution?

This sounded like it was coming from behind the cd player, but I know it was wind / speed related.
With a tail wind would not hear it at all (below 85mph). Wondering about air leaks at the firewall, or possible relationship to the non functional hood scoop.
Will be dropping it off at Toyota this week to see what they say.
The service guy told me "oh yeah, mine does that too" when I showed him a video of the noise at 65 mph in a 30 mph crosswind. Resorted to recording the noise on my digital camera when it became apparent that I was never going to be able to duplicate the noise here in town.
Mostly at 65mph with Steel rims 245/75r16 tires?
moves back and forth at 65 the dealer has tried everything swapped wheels with alloy
and larger tires seems to go away. From another taco they had in stock that was a TRD edition in reply to the other post those tires are bf goodrich and different size.
Tried different brands of tires up to michellins vibration still there ??
I have had lots of trouble with the Goodyear tires. In fact all four were replaced under manufactures defect over 1 year ago. Since then, I have had this vibration and when I brake, you hear and feel the truck shake . Is there a method to test if the tires are bad?
From another page: "If it only does it when you let off the gas while you're driving, then you definitely need to lube up the zerk fittings on your driveshaft like everyone else has stated. I had this same problem a few months ago and went everywhere to try and got the problem diagnosed, every place I went to could not replicate the noise. I got fed up and bought a grease gun at Autozone, lubed up all the zerk fittings, low and behold my noise went away."
Hope this helps.
The vibration has been there since I picked the truck up and is a low speed vibration when speeds are close to shifting especially at 20mph.
If your in the market for a Toyota be AWARE corporate will not justify fixing the problem if it is not a safety issue!!
There respone is that it is a CHARACTERISTIC trait of the truck.
Good Luck if you buy a Toyota and have a problem....
