Need opinions…might “try to” return 2011 Tacoma (vibration)

Still sounds kind of fishy to me. I'm a mechanical engineer and I pay real close attention to sounds, vibrations, etc. and my new DC doesn't have any vibrations that I've noticed. No "ticking" from the engine either. My previous chevy truck knocked all the time which is one reason why I got rid of it. It makes a little buzz noise right when I accelerate but it only last for a split second so I'm not really worried about it.

 

I agree it is weird, i'm not a 100% satisfied, but what am I going to do. Over the years it is going to experience worst things.

 

I have an 06 with over 100K miles and my truck has not had 1 problem. No vibrations. And dude the ride is like a cadilac after driving a jeep jk for 2 years. now that thing is rough.

 

If it worries you more then take it to a mechanic other than the stealership and see what they say. I have seen forums on driveshaft vibrations but it was usually on lifted trucks, never a new one.

 

It was interesting reading about your experiance with the vibration issues. If you review my past post, you will see I had similar experiances with three different Tacomas I owned. The problem was indeed identified as a torque converter issue and in my case the Toyota Engineers responded to the dealership after I opened a case and tried flushing the transmission fluid several times plus re-programed the transmission. Unfortunatly, the final answer from all the Toyota brains was "truck performing as designed" I was even given a new identical truck in a different color at no extra cost but it also had the problem. I also drove several other Tacomas and for what ever reason I felt the same type of vibration if I drove them long enough. The bottom line; most Tacomas have this very irratating vibration and I believe they don't know how to fix it! For the owners that somehow escaped this problem, consider yourself lucky. I was advised there was a TSB rear transmission mount designed to reduce the vibrations in 2009's and earlier but was told this mount is installed on the 2010's and 11's and not available at no cost. I do like my truck but certainly don't believe with all the technology this kind of issue should be acceptable for new vehicles.

 

anything here helpfull ?

I regret to inform that I too now feel the vibration at/around 20 mph. I first thought it was my tires but then I realized why would I feel my tires at 20 mph. The vibration is very similar to new mud grip tires when first accelerating. Good thing is that it is the only speed that I can feel the vibration. Once I go in for my 5000 mile oil change I'll ask the service tech about it and see what they say. I'm sure I'll get "It's normal." I'm glad I know it is coming from the Torque Converter thanks to this thread.

 

Vibration @ 20 MPH accelerating through 20 and coasting/braking down past 20 -

I felt the EXACT same issue on one that I test drove - decided to buy but refused that particular truck because of the vibration issue - test drove another one and no vibes so I ended up buying that one. Sorry to hear of your difficulties, not sure what you can do but keep hammering Toyota

 

There is a TSB out for Vibration between 15-25MPH...

T-SB-0132-08 JUL 08 Drivetrain - Driveline Vibration Between 15 - 25 MPH

I have the same Vibs but am waiting for an oil change to have them look at it.

 

Got the service department to look at the vibration yesterday. They first thought it was the tires off balanced, so they re-balanced all the tires. Still did not fix the the problem. I guess the good thing is the mechanic felt the exact vibration I was feeling and he didn't give me a line of BS. He wants me to bring it in and leave it so that he can properly try to diagnose the problem. The service man said the last truck he saw that had the same similar problem the guy had to get his driveshaft replaced. I might try to take the truck tomorrow and leave it to see if they can figure it out. I did have firestone ride-rite bags on it and he told me to take them off so that they know the truck is completely stock to check for the vibration. I took them off and noticed the vibration is not as significant now. Maybe when the rear end is higher (due to bags, or AAL) the vibration is stronger. Does sound like a driveshaft alignment issue. I'll repost if they figure out what the hell is the problem.

 

this may have been covered but the ticks are what seem to be the electrical plugs leading to the spark plugs, its them giving the signal. at drive throughs you hear them pretty loud

 

if it makes you feel any better, I just bought a used 05 and don't have any of these issues, so maybe it does just go away.

 

Could it be as simple as tire preasure too high? I know my ride is much better at 30 than even a few psi higher.

 

I was under the impression that this was mostly valvetrain noise, every Toyota I've ever listened to sounds the same way.

 

Of course. By lifting the rear with the bags your changing the angle of the driveshaft.

 

I've decided to leave the bags off. The only thing I tow is a 4-wheeler and I shifted most of the 4-wheeler weight to be over the axle of the trailer so that my rear doesn't sag that much. Seems to ride fine without the bags. I'll be trying to sell the bags on here soon if anyone is interested!

 

The stiff ride, yeeah thats a thing to get used to about driving trucks. It's why I hate driving luxury cars because everything is so "soft" and "plush"

Ticking noise is normal, when I first got the truck I thought there was something wrong, but nope it's fine.

As far as vibrations go, maybe it could be something as simple as a tire balance problem?
