Another vibration thread

I know there are a bunch of threads on this already and yes I have read them all. However none of them ever offered me a solution to my problem.

Here's the deal: I have a 2011 Tacoma access cab trd offroad 6MT and 12k miles.

In first gear at full throttle the truck severely vibrates. In 2nd gear full throttle 1500-redline the truck vibrates. These vibrations only happen under load and completely disappear in 4wd. It has to be driveline related.

The only thing I've noticed is the slip yoke on the rear shaft has some rotational play but not significant. The front shaft slip yoke has 0 play.

Has anyone had the dealer actually fix this problem?
What did they do to fix it?

Just trying to get some information before I take it in a waste my time. I will definitly be taking the shop foreman for a ride to show him.

 

anyone?

thanks however none of those apply to my issue. i have a vibration that shudders my dashboard not a noise.

 

No one has anything to offer?

 

When you excelerate hard the rear springs flex letting the rear axle rotate causing a sharp penion angle causing the shudder.I think most do it.Put on a set of traction bars like the old musule cars of maybe stiffen up the springs.I suggest just leave it alone unless you floor board it every time you take off.

 

Well the warranty department is gonna love me Traction bars are not the solution and I wouldnt consider anything like that anyways. This is something the dealer needs to correct cause its pretty bad.

The vibration in 1st gear and 2nd gear is way to severe. The dash board shouldnt rattle in a 2011 truck with 12k miles on it because of a gimpy driveline.

On steep inclines when taking off the driveline binds so badly that it seems exactly like clutch chatter. I can reproduce the chatter on every steep incline when starting in first. However in 4wd there is no problem at all. On level ground its not as severe because there is less torque on the driveline.

I can reproduce every symptom on a test drive with the foreman. Truck goes in next week updates to follow.

 

GL!

 

UPDATE:

Truck was dropped off at the dealer today. I had a technician drive the truck with me riding shotgun. We reproduced everything i described about and he told me that it wasnt normal. Ill hear back from them tomorrow.

Also my blower motor and clutch pedal assembly are getting replaced.

Ill keep you posted

 

Does your clutch assembly make a creaking sound when depressing the clutch pedal?
