Dick13, thanks for the information. I have a 2004 4WD V8 Ltd with fewer than 600 miles on it so far. I first felt what some call the "1700 RPM" vibration in 5th gear after about 200 miles. After 400 miles I started feeling it in lower gears also. I haven't fully characterized all the conditions under which it happens, but it seems to be mostly under light throttle, peaking around 1700-1800 RPM. If I accelerate harder, I don't feel it. It is at its worst when I'm trying to hold speed in 5th on a slight incline. (So for now, I shift down to 4th.) I'm taking it to the dealer next week.
I haven't gone though all of the relevant posts to check, but it seems that the problem may be unique to 4WD V8s. I had been wondering whether it was feasible to test with the front driveshaft removed, so it was very interesting to read that your dealer tested with the front axles removed. If you have time, I 'd appreciate it if you could give a little more detail on whom you've talked to. Do you have a name and number for the Tech Rep? (Is he a Toyota Corporate employee?) Do you know where the Engineering group is located?
One reason I waited for a 2004 is that I thought Toyota would have the problem fixed. At least I don't have the axle clunk problem. (At least, not yet.)

As soon as it warms up...meaning above freezing. I'm going to remove it and see if the noise is still there.
It may be a few days...probably this weekend I'll try it.

Dick13 & Toyo:
I'm taking my 4Runner in for service tomorrow for a door rattle and for the vibration problem you both describe. When I made the appointment, the service writer claimed not to have heard of the vibration problem. If either of you (or anyone else) could give me more definitive info about what the Toyota "engineering group" might be doing , along with any names and numbers, I would appreciate it very much.
I'll report what happens on my dealer visit.

See my post above with the links to the thread.
Answer to your question: nothing. Toyota/Lexus does NOT have a solution to this problem. There have been complaints, but no solution.
I would ask your dealership to either:
1. Rebalance your tires and realignment (you get one free before 12K miles), or
2. Switch out your tires. I have heard of one or two cases where the LEXUS dealership changed tires and resolved the problem. I believe the new tires were Michelin Cross Terrains.
Hope this helps.

I just brought my 2004 V8 4Runner (600 miles) in for a vibration problem also. I noticed on the way home from work a vibration at about 30-35 mph and the steering seemed a little sluggish. It also seemed to be louder than normal. Nothing really bad, it just didn't feel right. I was starting to think that it just might be me but brought it in tonight anyway. After reading all these post I'm glad I did.
Thanks!
Not happy about having to bring in a new vehicle though.

Thai,
Thanks for the advice. I pretty sure that a re-balance is not what I need for my particular symptoms, since they are engine RPM dependent and start at about 28 mph. However, it is always possible that a slight imbalance is helping make things worse at higher speeds. Same for tire brand. A brand change seems unlikely to fix it, either, but I have seen some miracles occur after such a change. I'm going on a long trip next week, which will be first chance to see what happens at high speed.
I got my 4Runner back from the dealer yesterday with the expected claim that the vibration is "characteristic of the vehicle." According to the service writer, the technician checked with some Toyota group in Houston and was told that's the way it is, there is no fix. However, he also got the impression that Toyota was still working on a fix. I hope they will try harder. Those of us who have the problem need to make sure Toyota knows we have it and don't like it.

I'm sorry. I should have been clearer. I do feel it in all of the gears, or at least in 2,3,4,5. 1st goes by so quickly it's hard to tell. But it's clearly there in 2nd, and gets more pronounced in higher gears. This is what I reported to the dealer's shop. They experienced it also, but for now are saying it is "characteristic of the vehicle."
Also, perhaps I should make clear that I don't have a bug deflector. I haven't installed anything non-stock yet, except a removable trailer brake controller. Also, I do have the Bridgestones, not the Michelins. I bought Cross Terrains for a previous vehicle. I liked them, but I didn't use them off road.
