Forgot to add that I went ahead and got the ECGS bushing upgrade and replaced all the seals of course. I didn't like the tool supplied that is shown in the videos to remove the needle bearing and instead used a slide hammer to remove the old bearing. It was stupid simple and no need to shove a part into the diff and prevent things from getting into the diff or worse, breaking the needle bearing apart and having the rollers drop in. Highly recommended. :cheers:
