Buzzy Vibration at certain RPM's..read before buying!

So mine is " abnormal" because it does not vibrate?!

 

no. mine is 4x2.

 

Take it to the dealer asap!!

 

Just picked mine up today. I can feel a slight almost unnoticeable vibration between 2100-2300 rpms. I only feel it when it's in those ranges and accelerating. Once I'm up to high way speeds and maintain it at those rpms I don't feel it. Hopefully that remains the case.

 

that is a nice looking truck - congrats. hope the vibe issue fades away for you!

 

just don't let them re-tighten the engine mounts

 

Is that the oem cover?

 

Yep, OEM tonneau cover.

 

I have been really trying to convince myself that my truck is not having this issue. However I am at a point where it is hard to ignore. I have a DCSBOR manual transmission and have been noticing this same thing. I think it is getting worse with time. I noticed it the first time with about 500 miles. I have 2300 miles on it now and just finished a 300 mile drive @75mph. Feet and legs are tingling as I type this. I notice it at most speeds, and RPMs, when the truck hits grades and works harder I notice it more. I feel it in steering wheel slightly, floor board mainly (I can feel my jeans vibrating against my legs), drivers door, and seat as well. Feels to me like its coming from the engine as I can sit in nuetral and rev into the 2000+ RPM range and feel the same floor board vibrations albeit less than when at speed.

 

That's a beautiful truck! Same color and model as my relative's new Limited. Love the color and interior. Although the vibs showed up on his, they are very minor compared to mine--probably 80% less intensity. I'd take a reduction to those levels.

Congrats on the truck! Sounds like you had quite a long wait.

 

My first thoughts was potential motor mounts being loose/overtight. But it seems some have had them re-torqued with no improvement.

 

Actually, those that had them re-torqued caused it to get worse....

 

Wonder if it is a bad torque spec on the motor mounts? Does anyone know what the proper torque spec is? I would like to check mine and see if they are even close to what they are supposed to be. Many have found rear u-bolts that are under torqued. Is it possible that the motor mounts are over torqued? It really feels to me like it is motor vibration coming through the frame.

 

Definitely wouldn't let the dealership re-torque the engine mounts. They did that on mine in an attempt to fix it and it got worse.

 

So that right there tells me it is something to do with the motor mounts. If they touched them, and it changed the vibration in any way, then the two have to be related. I'm not saying that it is all of the problem but if: Re-torque = more vibrations .....then vibrations and motor mounts are related.

 

If we know what the spec is supposed to be, we can check our specs against a couple of members that do not have the issue and see if there is any correlation. Sometimes it is much easier to trouble shoot these things ourselves than let Toyota do it and wait 2 years for a TSB. Maybe I am all wet here on the motor mounts being the issue. But your experience with the motor mounts seems to be the only thing attempted to fix and since it changed the characteristics of the problem, there must be some correlation.

 

What his post said Toyota did was loosen mounts to let the engine settle, then re torque. So it could be drive train angles of sorts? But maybe mounts too

 

Thanks for that clarification. So it could be that they changed the drive train angle to a position even farther out of spec. But the mounts are still the common denominator. In some way @DRBANE has an issue that changed by loosening and re-tightening the mounts. An interesting test would be with the engine mounts loose is the vibration present? Can @DRBANE or the OP verify that when the truck is in Neutral and the engine revved to their problem RPM range that the vibration is still felt to some degree? In my manual I can still feel the same vibration when I rev above 2000rpms while sitting still. The vibrations are subdued, but still felt in the same locations.

 

I can confirm the vibration is not present when I rev the engine to those RPM ranges in Park or Neutral. It's only there when in gear and the engine is under load.

 

Hmmm..... I will have to test mine again. I am now not sure if I had it in neutral or if I just had the clutch pushed in while in gear. However, I am sure that I could still feel the buzzy vibrations (best way I can describe it) in the floor board.
