Just a joke, or is that not allowed. I'm not a reconstituted member, just a regular new member. I'll be sure to check in with you before I make the next facetious comment. If I potentially damaged someones vehicle ill be personally responsible for the repairs.
Those wear metals are out of control. The only thing to do is use some gear oil on the next change. I think that will get the wear numbers back in check
Why would there be dirt in the housing? That's like saying what prevents dirt from getting in the transmission. I have a 2016 Grand Cherokee and Jeep Sahara they both use the filter cartridge and they're by far the easiest oil changes i've ever done.
