Thump when accelerating
I have a brand new 2010 Tundra. I do not have four wheel drive nor the TRD off road package. When I accelerate from a dead stop I occasionally feel and hear a thump coming from the rear end. It is just one thump and then the rest of the power ban is clean. Any ideas as to what this could be. Is it normal or is this anther trip to the dealer to have them look into this. This truck was one of the ones hit by the contaminated oil. Thanks for the help on that from the forum pages on this site. Again any help would be greatly appreciated.

It could be your rear differential, but if your lucky it will only be a U-joint or something simple. I would let the dealer check it out. If they are anything like the dealers around here, you are going to have to take the tech for a ride because they NEVER seem to find anything if left to thier own methods in the garage.

Yeah I have an appt with the dealer tomorrow. They want me to take the tech for a ride to see what it is. I am just hoping that it happens with the tech in the truck. If not when the rear end falls out of it they can replace the whole thing. the choice is there's. I would also like to thank you for hitting up a reply to this problem. I cant believe it, this is the first maintenance problem that I have had ever with a Toyota. I have had 4 of them all in a row. LOL I guess my luck had to run out sometime huh.

I had a 2008 that had the same issues but it never was something that was consistant so I did not bother to bring it in. I traded it in on a 2010 and now there are TSB's out for the VVTi check engine light and the accelerator pedal is being recalled.
Now they have stopped sales of Tundras. What the heck is going on here.
I am losing faith in Toyota pretty fast

It's a known issue with the rear differential. You can take it in, they'll replace the parts, but I've been told by a service advisor that it'll keep coming back. Good luck but at least get it replaced immediately.

I just got my 08 back from the dealer for what sounds like the same thing. The tech said there was a TSB for the dive shaft. They replaced the drive shaft. Crazy thing is they had to replace my radio also cause it went out and the only thing that i heard was fuzz and I could not control the volume....

There is a TSB called Thump/Clunk that deals with a similar scenario you may want your dealer to look up. It involves a quick (< 1 hour) replacement of the center drive shaft carrier bearing in 2007-2010 Tundra.
I don't have it with me for reference number etc., but it should be easy to find. I believe it is valid for 2x4 Tundra.

I have had this happen a few times with my new truck but it is really light. It is hardly noticable. The real thing that bugs me, and it might be normal, is the way this 6 speed shifts. Is it normal to wind out some before shifting. The RPM's don't ever get over 3000. I have never had a truck/car that has been an auto 6 speed so I am not sure how it feels. I am going to have the dealer check the bump issue but I really don't know what to say about the shifting.

Your truck is still learning your driving habits but yes it does take a bit before it kicks into the next gear. Often, it may not hit 6 and you can manually shift into it then.

When you say manually shift, do you mean switching from auto to manual to hit the 6th gear? Also, I read that you can put the truck into tow mode and it will shift normal, or like I'm use to in other vehicles. Have you ever heard this before?

Correct - just use the gear shifter to get it into 6th if it's not automatically doing it for you. When I throw it in tow/haul mode, I only notice it really helps slow my engine down for braking but I'll test it out later this morning. Tow/haul burns a bit more gas so I wouldn't suggest doing it though.
