Another Vibration Thread

Ok, I have read more threads then I care to remember and none seem to deal with this :

2008 Double Cab Auto

Only when under load, I get a vibration felt in the steering wheel and the pedal, it's not a wheel balance type of vibration, it feels like engine feed back, like if you had a bad motor mount. It is there through the rpm range but only under load, let off and it goes away. Rev in neutral and it wont do it. If you are on the highway cruising, you wont get ut until you hit a hill or accelerate. I cant see anywhere that the motor is grounding out when it tourqes. Its not a violent vibration but it annoys the hell out of me. On a long drive on the highway under load it would make your hand and foot numb

I have had it to the dealer 5 times. They have replaced all the motor mounts with no change....and now basically say that is how they are. I have been working on cars my whole life. I have never had this type of issue that was not due to something needing be replaced.

I have driven several other same model Tacomas and some of them have a much similar vibe but much fainter.


Any ideas? Anyone else get this?

 

My truck was doing the same thing at 57-62 mph and 1800 rpms. I lifted my truck and now it does it at 30-40 mph.

 

mine isn't speed specific, it does it at any speed under load. did it stock, with 5100s no change.

 

Same issue around 60 to 70 mph. Dealership said it was the allignment but it still does it.

 

if it is speed specific, in a certain range, I would look at rotating masses...like wheel balance or something.

 

They just balanced the tire again yesturday, as soon as they get done with the supercharger today I'll see if it was fixed.
