    I have read several posts about vibration during acceleration and have a similar problem with my 09 Tacoma (6 cyl auto, 4WD, 1000 total miles.)

    When I accelerate at a normal rate in first gear, I can feel a vibration in the steering wheel/center console as I go through about 2000 rpm or 10 mph. It does not happen in any other gear or at any other speed.

    I cannot notice it when I let the vehicle idle down a hill and then slowly accelerate. It is also not very noticable when accelerating up a very steep hill. It is pretty minor and you must be on a smooth road to notice it...it is almost as if the back tires are going over a series of very very small speed bumps.

    Any of you Tacoma gurus have any thoughts on this? Should I have the dealer look at it? One of the salesmen told me it was the result of "loading up very tight leaf springs with no resistance (weight in the back.) It will get better."

    My truck has been doing that since new and it has never gone away. In fact, I now have a vibration between around 42 and 48mph in addition to the 18mph vibration. Have about 13,000 miles on my truck and as soon as I pay it down a little bit more I will off it...not a happy camper at all.

    First, Salesmen are stupid.
    Second, Its probably the carier bearing. Mine does the same thing, and has since it was new. No biggy in my eyes, but if you want, you can try and use an axel shim inbetween the leaf pack, and drive shaft to help. Or, you can install a one peice drive shaft. :)

    42 to 48 mph vibes sound like a tire out of ballance.

    i've got the same thing on my 09. first gear only. it doesn't really bother me, so as long as it's not causing any problems i'll probably just live with it. unless they come out with a TSB for it, which seems unlikely.

    I did it again. Got tired of paying truck payments and gas and traded in for a 2015 Honda Accord Sport since I enjoyed my 2013 Sport so much.
    The only vibration I get is when I get into the 1800-2000RPM range.

    Seems normal enough.

    to me it doesnt really seem like a vibration but more of a "shudder" through the truck. mine does it all through 1st, up to about 22mph and it is magnified when towing heavy loads. it seems its most definitely the center carrier in the 2 piece rear drive shaft, the cross member just isnt rigid enough. swapping to a one piece shaft sounds like the best solution but is there a real reason that toyota made it the way they did?

    ehky go for a road test with a tech to show him the vibration you are feeling then ask him about this tsb they have an updated rear trans mount for driveline vibration between 15-25 mph.http://www.tacomaworld.com/forum/at...acoma-auto-v6-access-cad-trd-t-sb-0132-08.pdf

    Great News! Thanks for mentioning this Beef! I've beat my head on the service manager's desk several times over my 'shimmy' at 15MPH. I've even had a tech ride w/me and had them 'document' the issue....now I have the goods.

    I'm on the phone tomorrow to set this up. :proposetoast::proposetoast:

    beeftaco,

    I think that I'll do that. I appreciate the info. Just one question, though: If in fact it is a faulty carrier bearing, wouldn't the shudder/vibration get much worse with increasing RPM's? As I said, the only time I feel it is between 10-15 MPH in first gear only.

    The TSB is for replacement of the rear trans mount the shudder is not in the drive line itself according to Toyota.
    I think it might balance its self out at higher rpms or your just not feeling it. I have a shudder right around 12 13 mph but haven't changed the mount to see if it goes away or not I am blaming it on the tires right now.:p

    Not to keep beating this horse, but has anyone has this TSB done to their ride yet? Driveline Vibration between 15-25 MPH 0132-08. It came out in mid July.

    Curious to see if this actually solved anyone's problems...

    I have a 2009 and jsut recently had an OME read spring pack installed with new shocks. I had the front done too. I had the front done a few weeks ago and did not notice any change. They just finished the rears today and now the thing vibrates like hell in the low RPM and speed range. DAMN IT! i woudl say yes, looks like it carried over. The odd thing about it... I either did not notice it at all during the first 4000 miles of driving or it came about as a result of the rear leaf pack... thoughts?
