Vibration @ 40-60km/h

Purchased a 06 4x4 Crew Cab 4.0 a month ago. Noticed it after 3 days of driving. Clearly I didn't test drive it enough. Vibration from rear end between speeds of 40 and 60km. I got new tires put on it this week and balanced and the vibration is still there.

Not sure when the U-joints were last greased, or the dif fluids changed. Was thinking of checking the angles of the shaft & pinion etc. as other threads have indicated.

Any other suggestions for me?

 

Well I climbed under there and from a bit of research I can't grease the u joints cuz its a 4x4 and the u joints appear to be shot. (grease half moon around the u joints.) black crap on them.. etc. So I am thinking this is the culprit. It does kind of clunk when I shift from park to drive. Truck is at 165,000kms.

 

with a 4x4 there should be a zerk on each spider

 

Mine looks worse than this... https://youtu.be/oUjkc8KsJAs?t=28

 

I would change the U Joints and see if that dos the trick .

 

Lifted? 3" approximately?

 

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
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 in 2 wheel drive ?
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 .
