To rule out drive line angles , try adding weight to the box of the truck as a diagnostic and take the truck for a ride .
Its an easy test and will answer a few questions for you .
I will post up my vibration chart . Maybe that will help as well
Lets look at some Vibration diagnostics . Anytime someone asks a vibration question , I copy and paste this .
I believe 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 accelerator pedal ? This is a misfire test for your engine
Does the truck vibrate while holding the brakes and hitting the gas - Automatic ? This is also a misfire test for your engine under load
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 neutral and coast to a slow roll without using the brakes ? What happens when you turn the truck of in Neutral at highway speed ? Can you still feel the vibration ?
Does the truck clunk over bumps ?https://www.tacomaworld.com/threads/tacoma-loose-bed-design-flaw-explanation.388873/
Does the truck vibrate as you are braking ? When was your last brake job ? Consider the front rotors may be warped or the rear drums are out of round .
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 ?
Is the vibration caused by your torque converter ? Tapping the brake pedal at highway speeds will release the torque converter clutch . You are not actually hitting the brakes ,but manipulating the brake switch . If the vibration goes away you can expect a misfire or a converter clutch issue .
Read here for more information regarding automatic transmission diagnostics
https://www.tacomaworld.com/threads...th-pics-for-second-gen-4-liter-trucks.289913/
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 ?
A good vibration technician can tell immediately if your vibration is caused by the rotating speed of your wheels or by the rotating speed of your driveshaft .
If you go through this list carefully , you should be able to narrow down where the problem is .
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 .

You won't believe what it was:

The god damn free grill I got.
Took it off and sound went like the n-sync song " BYE BYE BYE"

So much for my arm chair diagnostic
I hate the fact that I cant test drive over the keyboard .
Maybe someday

Shuddering is a word used in drive train terminology and has nothing to do with wind characteristics

Aerodynamics I knew it. Wind can be very strong.

OP was ready to drive the taco off the cliff because of some front plastic.

Yep. Was pulling my hair out. But I had a few things to check.
