Shaking! Suspension, tranny, drivetrain, or WHAT?

I am having a shaking problem.
From a stop, with moderate acceleration, at 5mph, there is a shaking for a half second. I first thought it was bumps in the road, but not the case.
Same goes in reverse.
If I accelerate slowly it does not happen.
If I slow down to 0mph it doesn't happen at 5mph.
It is not when it shifts.
When I try it in L manual, it does the same.
I never have any other shaking at any other speeds.

Any thoughts?

This is on a 2010 V6 Auto DCSB 62K miles.

 

Vibration on acceleration, normal occurrence. Mine has done it since new.

 

As the same choices on fb post, axle wrap , ujoint carrier bearing.

 

These are some things you need to try before you post .Not only will it help you troubleshoot the vibration but it will narrow things down for some of the guys that like to try and help you with your vibes .
Vibrations usually get all mixed into the same pot and a lot of posters try and fix their vibes using what others have done without properly diagnosing their own issue .This causes additional frustration and all kind of cash $$$$$$$$
Take some time and try and narrow it down because the dealer is not going to help you .
Dealers may try and fix the vibration but from what most people have said , nothing the dealer does fixes the vibes and shudders .
Are you effected by the TSB ? http://www.tacomaworld.com/forum/2nd...n-tsb-out.html

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
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
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 .

 

WOW! that's a lot. I have already tried some. I will get on that and report back, thanks.

 

Most likely it is happening right at the connection between the 2piece drive shaft. The first piece is straight off of the transfer case and the angles down. Mine does this now since I lifted it. It's only from dead stop to a quick acceleration. If you have a go pro you could mount it and check out the footage to see if that is the issue.

 

U-Joints...

 

Has it always done this or is it a new problem? From your description, it sounds like the regular problem of driveline vibration under acceleration. Do you have the 3 or 4 leaf pack springs in the rear?

 

@ COLTS TRD, you are the winner? Lol. Super bad U joint. Went ahead and changed all 3.

 

^ wow
