      I'm bummed as hell. RalliTek upcharged hard for shipping to a close part of Canada, I'm at $100 for a $30 part. Turns out the huge shipping fee actually had nothing to do with duties and customs, because now they're asking after another $50 on top of how much extra I already paid.

      Should've made my own out of silicone.

      Good product

      No issues with installation or performance.
      Rectified alot of drive line vibration.
      I imagine if i had healthy control arm bushings i would have even less or nondriveline vibrations caused by after market cv axles

      Thanks for the review!

      Transmission Mount Insert Bushing

      Bushing came well packaged and with some lubricant for insertion process. Using a small benchvise to fit the insert to the mount I found some outer lips of the insert needed to be trimmed off with a sharp Stanley knife.
      This was to allow some relief during the start of the press fit proceedings in the vice. The supplied rubber lubricant helped this fitting process as described in video.
      The transmission now is held tight with some flex in the mounts.
      No more rattling on ignition start up and more confidence in off road driving.
