Vibration problems

Hey Guys:

I have this weird vibration. I saw the same exact description in another thread after a search but it did not have a resolution. I am reposting below since the problem is exactly like mine. I have a 2005 4Runner V8 Limited with 132 kilometers on it. I think perhaps its a wheel bearing but I am not sure. Can anyone comment. Steering from left to right seems to fix the problem for a second. As soon as the truck straightens the problems begins again.

Here is the description I found that is identical to what is happening to me:
"I have had my 2004 V8 Limited for a few months and it has 74,000 miles on it. It is evident based on the maintenance records and condition of the vehicle that the previous (and only) owner took decent care of the vehicle. As you all know, once you have had a vehicle for sometime you become aclimated to how it runs and how it sounds. And this Toyota runs smooth, the engine is quiet, the transmission shifts normal and smooth.

However recently, and I am sure it was not like this when I purchased it, I have noticed something. Basically, at around the 1500 rpm range, while accelerating or anytime the engine is increasing power to the drivetrain, I get a resonating noise similar to a 4 cylinder car with a exaust beginning to go bad. I can feel the vibration through the pedal, steering wheel, shifter and hard plastic floormats. Now anything above or below this RPM range it is not noticeable. Also, this does not happen 100%, but I would say a majority of the time it is present. I would say it resembles two mechanisms not quite meshing together smoothly...that's about as well as I can describe it."

Would a slight harmonic/resonation in the in the steering rack cause your issue?

I have a slight vibration the may be related to the steering rack. (Thanks 810Moto!) Look at this product description, does it fit your symptoms? It fits mine even though my tires are not huge. Mine did it somewhat with stock tires too. The reason I am even barking up this tree is a guy at an Indi Toyo shop suggested he might be able to fix it by messing with the rack mounting. He had to study the bushings first. I suspect he was alluding to the kit in the link.

I thought this was going to be a brake or wheel vibration thread.. lol..

I noticed something similar in my truck today. I'll see if I can duplicate it to get more familiar with how it's happening.

it's a high frequency vibration right? Like in a stick shift car, flooring it, overloading the engine with too high a gear in the low rpms?
 
Thats exactly right Midnight Runner.

It feels like the car is in the wrong gear. My friend says to me today why is your car revving at 3K rpm. I said its not its actually 700 RPM. He thought it was stuck in 3rd gear.

I don't know what to make of the vibration. I'm on stock wheels and tires, so I don't think it has anything to do with the steering rack.

I doubt it will cause any issues. It's probably just the harmonic resonance of the engine at that rpm.
