Cost of ownership metrics, you mean the shit Ford prints in everyone's owners manuals that tells them when they should be doing this thing. God forbid people actually follow the instruction manual. But according to you every single Ford truck owner should know better and it's their own fault when it shit breaks cause Ford is too ******* stupid to actual print "Metrics" that support regular owner usage.
Rear Diff not having a drain plug from factory just means those Manufactures have been dry ******* you all for that long. Funny how every aftermarket diff includes one, and a magnetic plug. Probably cause they know better. I have half a dozen B4G rear diffs here in my shop along with the same amount of Getrag transmissions, so yeah IDK what a magnetic drain plug looks like when it comes out or how that sludge does indeed affect every single thing it comes in contact with and will destroy bearing races in no time.
East Coast Gear Supply here in NC did the repairs on my truck and they even state the 9.75 rears are know for their pinion bearing failures at like 90k. Mine had the same pitted races as every single one they have found or encountered. Hell they do they so much it only took them 5 hours to rebuilt the entire rear end of the truck.
Now that it's all fixed, time to sell it and buy something better.
