Viberation 30 to 35

viberation at 30 to 35 mph 2008 toyota tacoma

 

What'd you do to it?

 

Nothing bought used Tuesday

 

Stock suspension? Check ujoints!

 

Looking at your signature it looks like it's had a lot of suspension mods done. Did you test drive it before you bought it?

 

Lets look at some Vibration diagnostics . Anytime someone asks a vibration question , I copy and paste this .
I believe there are at very minimum at least 12 different vibration issues assosiated with the Tacoma and all the vibrations / shudders get mixed into the same pot when members start posting leaving members scratching their heads .

These are some diagnostics to try . If you bring your truck to a shop , they will be trying most of these to narrow your vibration down .
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 slid under the truck and inspected to see if any driveshaft weights have fallen off ?
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 off 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 .

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 that are incredibly difficult to balance ? 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 .

What kind of poll is that?

 

This⬆️

 

Yup, that book is right on the money lol if I was a betting man, I would say Needle bearing. But definitely go through the posts above to narrow down your issue.

 

If your truck is lifted and 4x4, see if you can grab ahold of your driver's side CV joint and check for play where it meets the front diff.

 

That might be the best post in all of Tacoma World.

 

TLDR

 

Check u joint and carrier bearing sir

 

What does that mean if there is play in the cv joint? Im having a similar issue and my cv joint pulls in/out and up slightly and theres a small leak coming from the oil seal as well

 

It is an indication that your needle bearing has gone out in your front diff. If locking into 4wd stop the vibrations that pretty much confirms it.

 

One thing after another.. So my oil seal is torn, my wheel bearing is toast, and my needle bearing has also gone. Jesus I have some work to do lol

 

At least you only have to take it apart once

 

Always looking for the positives, I like that haha. Only disadvantage to having one vehicle is now I cant drive around and buy the parts myself. So its way more painstaking to get replacement parts
