Vibration MEGA THREAD!!!!!!

Very good shaft I was almost going to buy one but I came up with the 4runner fix for much less. Read some of the related links lots of info there.

 

I was about to pull the trigger on a Tom woods driveshaft, I think they are $500? Or around there, anyone take measurements?

 

ok but really, any fix for this?

 

So much for being a MEGA thread. lol

 

I keep looking at all the threads that link to another and the only fix was some guy replacing his driveshaft, the TSBs didnt work

 

And even then I dont think it's a 100% fix. I think I read of some people still having the vib after dumping the money on a one piece DS.

 

For me, I had a vibration that could be felt by my feet in the floorboards and the truck would make a moaning noise that almost sounded like a tire issue. I got this vibration around 30mph but it was really pronounced at 55mph. Dealership initially said nothing wrong but I took it back and their master mechanic said it is likely the right front bearing. I replaced that one and the vibration went away in the passenger floorboard but not the drivers side. I replaced the drivers side front bearing and Glory Hallelujah the vibration was GONE. This made such a huge difference it's like a different truck. It was driving me mad. Dealership wanted over $1,000 to replace each side. I bought upgraded KOYO bearings from ebay and did it myself after watching a couple of youtube videos. It was certainly a do-able job for anyone mechanically inclined. I have a 2010 4-wheel drive Tacoma with 68,900 miles on it. Other posts state that these bearings go out around 70,000 miles.

Vibration? Think about your front wheel bearings.

 

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 ?
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 .

@gearcruncher and other Tacoma sages.

I believe I have two distinct issues:

A vibration upon accelerating from stationary. This is a pretty violent vibration, shaking the passenger seat, the hood, the steering wheel, and floorboards. From 0-10mph. Above that, no issues. For example, say the speed limit bumps from 45 up to 55...no vibrations during that acceleration.

This vibration either completely disappears or greatly diminishes in 4x4. Hard to tell because the roads are so awful here. This all started about a month ago in the middle of a road trip.

My second problem started about a week ago and is a loud clunk when I am slowing down, perhaps at shift points I can feel it in my feet, sometimes it's worse than other times. It seems to happen during braking and coasting alike. It also seems to happen in H2 and H4. It was hard to tell for sure on the road I was on, but this clunk might have gone away in neutral.

Any advice? That's the best diagnosis I could come up with right now. Any help is greatly appreciated!

 

Bump, any help is appreciated.

 

you can try taking out the rear driveline and putting it in 4x4 and driving around. If the problem goes away you know its in the rear driveline. Sounds like you might have a bad u-joint or carrier bearing.
