This is gonna a head scratcher....so I took a vid of my whiteline diff bushing and In basic words it is moving up and down like a blown oem rubber bushing.There is nothing visually wrong with the sleeve is still bonded with the poly and is sitting flush with the diff cover. I checked the other bushings as well and even up to my trans mount and everything checks out. Not really sure what's wrong here and am kinda frustrated because my poly bushing is deflecting like a blown oem one. Any idea?

There's going to be some movement. Can you post the video? Is everything torqued down to spec?

The poly bushing is supposed to move. It's stiffer than OEM and it's not fluid filled, so it will never leak. It's not supposed to be solid.

If you want to minimize movement further without adding NVH, look into a diff brace. If NVH is not a concern, then go with solid bushings. I'm running with Whiteline diff bushings + Gktech diff brace, this combination in my opinion, is very good for street use. I have not noticed any additional NVH. Little to no slop in the drivetrain compared to stock setup. I'm very happy with it. Note that the front, side (L & R) whiteline diff bushings should have the thicker halves on top, against the body of the car. The Whiteline instructions from years ago depicts the thicker halves installed on the bottom, which is incorrect. It appears that Whiteline has since removed these instructions from their website (link is broken), but you can still find the old sheet if you dig enough.

Yea here it is

Everything is torqued to spec and nothing is loose. In the video I was in first gear on and off throttle around 3500 rpm so pretty torque heavy situation

Yeah, that's pretty normal movement. Nothing defective/broken there, also nowhere near as bad as a blown OEM bushing.

Agreed. Looks fine. I bet you're no longer getting that "clunk" during hard shifts like you would with a blown OEM bushing.
