Troubleshooting vibration at 55mph

2012 DCSB off road stock with 265/75/16. 50,000 miles

Any time I get between 53-58 mph and am either coasting or not accelerating I get a vibration. It doesn't register through the steering wheel just the truck. I just had the tires ballanced and rotated. Could it be an alignment issue? There's no record of an alignment being completed on the truck at the dealer where the previous owner had maintenace done. is the dealer the best place for an alignment?

 

Usually No. Find a good shop that does front end work. Probably cheaper and better.

 

Most likely a drive line vibration, some trucks end up leaving the factory with vibrations.

The U-joints probably have never been greased, so grease them and start from there.

 

Could be an alignment issue, poor wheel/tire balance, or even front diff needle bearing (though that's usually 30-45mph and it pulsates). My Taco has less than 10k on it and I've got a front diff vibe when in 2WD.

 

I've greased the drive shaft every oil change since I bought the truck so that's doubtful. I was thinking it was driveline vibe as well but my speeds were much higher. To test that theory I'd just shift into 4h on a straight road when it's vibrating and see if it stops?

 

Based on your initial post, it only happens from 53-58 and there is no load from the engine accelerating the vehicle? What happens above 58? If you coast in 4th gear and start at 65, the vibration begins at 58 and then disappears as you drop below 53mph?

And this occurs throughout the truck- specifically NOT in the front wheels and ONLY when the rear wheels are not acclerating the vehicle.

Does it happen if you hit 65 and put it in neutral and coast down through 58 to 53 mph?

 

Lets look at some Vibration diagnostics .
I beleive there are at minimum at least 12 different vibration issues assosiated with the Tacoma and all the vibrations / shudders get mixed into the same pot leaving members scratching their heads .
Have you greased your driveline ?http://www.tacomaworld.com/forum/tec...rks-total.html
Do you know how to grease your driveline properly http://aftermarket.federalmogul.com/...%20FAQ%27s.pdf
Have you checked your carrier bearing https://www.tacomaworld.com/threads/how-to-replacing-carrier-bearing.260283/
Does the truck vibrate in park or neutral and does the vibration change with accelarator pedal ?
Does the truck vibrate while holding the brakes and hitting the gas - Automatic ?
Does the truck vibrate in neutral at a stand still ?or coasting in neutral ?
Does the truck vibrate in 4x4 ?
Does the truck " Only vibrate " from 1st to 2nd gear ? https://www.tacomaworld.com/threads/vibration-when-accelerating-from-stop-anyone-fixed-it.300155/
Does the truck only vibrate in 2 wheel drive ?https://www.tacomaworld.com/threads...differential-bearing-vibration-thread.152173/
Does the truck vibrate with the serpentine belt removed ?
Does the truck vibrate cold or hot ?
Does the truck vibrate if you select nuetral and coast to a slow roll without using the brakes ?
Does the truck vibrate as you are braking ?
Does the truck vibrate with weight in the truck or empty ?
Does the truck vibrate while upshifting ? Have you checked your trans fluid ?
Does the truck vibrate while downshifting ? Have you checked your trans fluid ?
When was your last transmission fluid service ?
Now that you have a lift kit installed the truck vibrates . Did you cancel your drive line angles ?
Have you looked at the condition of your tires ? Toyota says to rotate every 5000 miles .Tacoma tires must be road forced balanced using the Haweka adapter on the tire machine tsu00296.pdf
When was the last time you rotated your tires ? Are you using LUG centric aftermarket wheels ? have you considered " HUB centric rings " http://www.amazon.ca/s/?ie=UTF8&key...vptwo=&hvqmt=e&hvdev=c&ref=pd_sl_7ybe1f1pby_e
Have the balance weights fallen off the tires ?
The proper and only way to test for bad universal joints is with the driveshaft removed . You cant tell if the universal joints are seized or tight spots with the driveshaft on the truck . You may see play in the universal joints , but you wont be able to properly check the u-joints without removing the driveshaft .All it takes to create a vibration is one seized universal cup and there are 4 cups within each joint .
With this said , you cant tell if that cup is seized with the driveshaft connected .
Removing the driveshaft and manipulate each universal joint by hand from side to side feeling for tight spots as you go is the only way to check for bad u joints
If you beleive its bad motor mounts or transmission mounts , grab a big pry bar and pry at the mounts to see if the rubber is torn or weak .

well done sir.

 

I will check tonight

 

I just found the cause of my vibration on my '07 TRD Sport 4x4- it is the center drive shaft support (carrier bearing). Give yours a shake...
