Vibration from 65-75

Had new tires installed in March then recently rotated and balanced. My alignment is spot on. Vibration begins at 65 and then dies off at 75. New carrier bearing. Honestly feels like front end.

Any suggestions?

 

I’m chasing a humming at the same speeds .

Check lca’s bushings, lbj's also front wheel bearings .

drive shafts not balance or put back incorrectly .

 

If they were put on in March, why just balanced? That may be issue now. They were not balanced correctly.

 

Chasing the same issue. I even installed a completely new driveshaft. Still there. Tires and wheels are new and balanced. Seems to be a very common issue.

 

They were balanced at install and I live in mass so our roads are shit. I never do highway and had this issue both times I did get on the highway since March so I figured I’d balance them. I work at a dealership anyhow. I wanted to eliminate that.

 

And the balancing was last week. It’s still an issue with the shaking.

 

Were your tires and rims road force balanced ?
Was the Haweka adapter used when installing the tires on the rims ?
Did the truck begin to vibrate after the new rims and tires ?

Bushings and alignment?

 

I had the same issue around 50-60 mph. Replaced my carrier bearing and two u-joints and that seemed to fix it. Smooth now.

 

I replace my carrier bearing last may with

$100 spicer 211750-1x center bearing compatible with select toyota models 1995-2021

spicer 211750-1x and now it as slack.

my u joins looks originals I think is time for new ones with 187k
@Logans2001 did you feel that humming /vibration on ur gas pedal also like mine?

 

Could be a lot of things. Jack up the front end and look for loose stuff. My first guess is always u joints.

 

Ya wouldn’t hurt to hit those u-joints I bet. My whole cab would vibrate. Came on pretty quickly too like within two weeks it got worse and worse. Use oem.

 

This maybe a wild guess but maybe you lost a balancing weight on the driveshaft? Did you replace the CB with OEM? The aftermarket ones can be complete crap.

Was the CB installed correctly?

Is the vibration dependent on whether you're on the throttle or not?

I was chasing vibrations after i lifted my taco a few months ago so I'm familiar with these woes.
