Legend!

Thanks so much for the great YT content showing how to install the new TPU part - unfortunately, I did not test my new 8170 using junk era commons before realizing I had an issue.  Thankfully, I caught the issue quickly, and I'm super frustrated to have to buy a part to fix the issue, but I'm super thankful you've provided us a trouble shoot option.  I think I can handle the part of putting the spring and loader arm back together, but I'm a little confused on how to remove the housing that it goes into (the part that slides out where you remove the wheels from).  Any chance you can post a walk through on how to remove that housing?  

Please disregard, I see you uploaded a separate video on YT with a step by step for this.  Thanks again!

Thanks man.  I found your video from about 3 years ago, but I'm strugging with that tab releasing the right side on mine.  I'm not nearly as tech/mechanical savvy as you are, and I'm petrified I'm going to snap something off.  

Sure, I will make an updated video for you on this and post it tonight if that is ok
