slight vibration at 1800 rpm..

anyone else truck have a slight vibration start at about 1800 rpm and kinda disappear at 2100 rpm? this is in every gear, 2006 auto DC 4x4 SR5. can feel it in the gas pedal, floor and steering wheel, almost feels like a power band kickin in on a 2 stroke dirt bike, ...

I also have that very vibration in my 2010. Did you get yours fixed or is it "normal?"

 

Is your truck lifted?

 

Mine is not lifted. I do not feel it in the seat, under the seat, in the shift knob, dash, etc. Only the wheel. The front end has been aligned. It did it from day 1. I have all of 3500 miles on it. It is a like a buzz in the wheel - like a vibrator - not a shake or shimmy or shudder.

Only in the power band, only during the application of gas - even a light application of the pedal (or via cruise control).

In 2WD, all speeds, in the RPM range from 1800 - 2100. Fades at 2100.

It has to do with the engine/transmission, I think.

 

holy thread revival batman

 

I've got it too, but mine's a prerunner. It's got 4400 miles on it.

 

I went to a dealer and a senior tech and I drove another, identically equipped, new on the lot, access cab 4.0 auto trans and it did it too.

My current conclusion is that it is an annoying behavior of the truck, that's all. It is really like a hum, but no sound, a harmonic thing during those rpms. Something about the combo of the V6 and auto trans creates this harmonic when the engine works and the steering column transmits it. I drove a manual and it didn't do it. Am going to another dealer to do the same thing and see.

If this can't be fixed, I may not keep it.

Not done with this yet. Try what I tried, and let us know what you find out.

However, my truck is great in 4-lo in the muck and ruts. So many great things about this truck. What other PU will do that as well?

 

I noticed today, after driving on the freeway for the first time since it (5100s 1.75 and No TSB), that my truck is kinda all over the place. I looked at the front tires at they appear to have alot of postive camber. I'm bring back to shop in morning, let them adjust the alignment, rotate tires, then I'll see what happens.


edit:
I realize just looking at the wheels isn't an indication but the appearance along with the slight lift, wandering, and general available information, I'm only assuming too much camber. I neglected to get a printout before I left. My bad there...

 

its how every toyota tacoma I have ever drive drives. my personal thought on it is its the rear gear whine/vibration

 

Went to another dealership and drove both a 2010 V6 Manual and 2010 V6 automatic. The automatic has exactlly the same 1800-2100 buzzy thing in the steering wheel as mine and the other one I drove - the manual doesn't. The odds of three of them at three different dealerships being screwed up exactly the same way are really small. It is all about the transmission, and it's the norm.

Annoying but normal -- Toyota should TSB this. Probably would have bought the six speed had I noticed it on the test drive. But the auto has its advantages, too.

I'm going to find a neoprene steering wheel wrap thing and forget about it unless it gets bad.

Hoping for at least 200,000 miles from this otherwise good truck. I really like the way I can crawl it super slow off road without killing it - easier with the automatic trans.

 

Cold, my 2010 6 speed does it too dude.. it started after about 1000 miles.. the difference with the 6 speed its way less noticeable (I have driven an auto and its very noticable).. mine only does it at 2100 rpm exactly , no other rpm.. with a load (towing my boat) or uphill/high winds..etc its more noticeable.. I have a hunch its the rear mount..

 

Now normally, I'm completely adverse to casting Life on a thread. However, this thread here is of a particular importance to me. I, too, experience this slight shutter at the aforementioned RPMs. I test drove this beauty before I bought it, and I was slightly unnerved by what I felt. I asked a very mechanically-inclined friend who works for Lexus what he thought the problem may be. Without actually driving it, he offered it could either be a bad alignment or an imbalanced tire(s) issue. After the purchase, I had an alignment test done, and the tires deflated/inflated to reflect proper specs. The shutter is still there...

It's at this point I joined the forum (today). In my mind, I was using what little mechanical knowledge I have to guess the problem: bad motor mounts, stabilizer bar (?), misfire in the motor somehow... I have no idea, lol. I'm not that mechanically inclined, so I was preparing myself to call a shop (more money I don't have). After reading this thread and seeing that quite a few of these babies have this symptom, I'm rather relieved. And I agree: Toyota should have this officially documented and released to the public somehow. May be bad for business (who wants to buy a truck they know will "shutter" - oh wait, Jeep I'm looking in your direction LOL), but it'd save us a lot of unneeded worry. Guess I'll just learn to live with this shake. That just sounds sooo bad to say tho, vehicle-care-speaking >.<

 

LB, i have know way of knowing but i think mine is doing the same thing.
is it just a bad drive shaft carrier bearing?

 

I have the same thing. I thought it was a mount, had them all replaced under warranty..no change. If I rev it in neutral in the driveway at the same RPM I feel it, so that removes rear end.

I heard from one master tech that is a harmonic vibration from the exhaust traveling close to the steering rack and column and it transfers up to the steering wheel.

I am wondering if anyone who has experienced this has upgraded their y pipe and if that made any difference?

 

Here is what I did: I went to a Nissan Dealership and bought an Off-Road Xterra with 30 more horsepower, a fully boxed frame and a glass-smooth driveline. 30K miles later it is oily smooth and awesome. Same powertrain in the Pro-4X Frontier. One piece driveline, fully boxed frame, a better truck in every way, IMHO.

Fixed it permanently, that's what I did...

 

anyone?
