Fix for 15-25 MPH vibration

Yesterday I took my car to Roger Daniels Alignment shop in Santee to get an alignment, great work by the way. Got to talking to them about the 15-25 MPH vibration and they said they had a guy come to them with a 2012 DCSB 4x4 with 6" fab tec lift and he had a good vibration.

They said they solved the issue by injecting the carrier bearing with a stronger poly uriethene compound that they mixed. The guy never came back said it completely took care of the issue. I'm taking my truck in soon for them to do the same thing. Its been two years since they did his and its still working great.

Thoughts?

 

I plan on doing just this when I get a chance.

 

Is this "stronger poly injection" only for 4x4's? I have a steering wheel shake on my 2WD @ 50-60 mph (accelerating/decelerating).

I found some info using the search but now I can't find it?

 

Mine has that, it's pretty infamous among the 2nd gen Tacoma. There are threads about it.

 

Sounds like a balancing issue.

 

I'm not furmilure with the 50-60 MPH vibration this is only for 15-25.
