ecgs bushing did not fix vibration. please help

I installed 5100 billys 887 springs 1 inch rear block. had it aligned. and had vibrations at around 25 mph. goes away in 4wd. installed ecgs bushing and still have same vibes. any ideas would be great

 

Did you add a diff drop to the setup? If you did take it off

 

Rear axle shims? Carrier bearing drop?

 

no diff drop,rear axle shims or c/b drop

 

would a carrier bearing drop help?

 

No, for 1" only don't mess with that shit.

If you installed bigger tires too they might not be perfectly balanced

 

ko2 265/75/16. could a bad alignment cause the vibes?

has anybody had the problem not fixed with the ecgs bushing

 

Alignment sheet available? Who installed the ECGS, yourself or a shop? Maybe road force balance your tire....I'm assuming stock UCA?

I've had no problems with my ecgs install.

 

A shop did the ECGS install. Yes stock UCAs.

 

Lift was installed properly with everything torqued correctly(in the air vs on the ground)?

Occured after lift? After tires? Both?

Change wheels? Hub centric? Lug centric? Torqued properly?

Road force balanced? If lug centric, was it balanced using a lug adapter instead of hub cone? If oversized hub bore do you have hub rings? Does it change rotating tires around?

Did you have it aligned after lift?

Does it increase or decrease with wheel speed?

In a certain speed range?

Under acceleration through a certain speed range? Under deceleration through a certain speed range?

Higher frequency than wheel speed?

Feel it in the steering wheel or in the body?

Still goes away in 4wd?

Point being, it could be anything...
It helps to be as detailed and descriptive as possible to help narrow it down.

 

Looks like things I would ask
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 associated with the Tacoma and all the vibrations / shudders get mixed into the same pot when members start posting as they are trying to help . This leaves the guy trying to fix his truck scratching his head . Process of elimination is the key .

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 .
Universal joints need to be lubricated at every oil change . Can you confirm this has been done ?
Have you greased your driveline ?http://www.tacomaworld.com/forum/tec...rks-total.html

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

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 body and frame mounts ? if the body is resting on the frame with no insulator , you are going to feel droning ..Thats for sure .
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 "

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 .

As your suspension begins to age , the drive line angle will change creating issues


Want that vibration gone ?

REVIVE. Hey OP, did you ever get this resolved? I got the bushing installed but my vibration is still there. It got better, but it still noticable. Thanks!

 

Did you ever figure your issue out? My truck also has vibration after the bushing install. Between 40mph and 55mph
