Post Life Vibrations

So I've recently installed Bilstein 5100 w/ OME 885 and AAL onto my 2015 DC TRD Sport. I've noticed some pulsating vibration underneath my driver side floorboard while driving. It would occur between 25-45 mph. When I turn on 4Hi the vibration would go away. I tried the OME carrier bearing drop but the vibration is still present.

Any recommendations what it could be (adding rear shims or new bushing)?

 

Google "tacoma needle bearing noise"

There is a warranty part that toyota might replace your needle bearing with. They might decline because of the lift.

The real solution is the ecgs bushing. You can get all the info you need about that from google Too.
