Just to wrap this up. I finished everything on Monday night. Everything went well with the swap and I drove it for the first time yesterday in 10 weeks! It felt great to drive again. Took about a solid 12-14 hours of actual work. A lot of that was spent making sure the diff was properly supported and not going to fall off and crush me since I did it by myself. Overall not a bad process at all. 2 of the 3 mounting ears of the diff housing were cracked and the last one was sheered off. The case also had a decent size crack which is where the fluid was leaking from. I replaced the transfer case fluid too while I was under there. I was hoping to install the thicker IWE rings from RPG that I had ordered but its been over a month since I ordered and they don't have an ETA when they will come in. I'm very happy this whole thing is over and I can get back to driving my truck. Already have a trip planned to Glammis dunes to test everything out. Overall this experience has left me pretty disappointed in Ford as a company but I have never missed driving any vehicle as bad as my Raptor. It felt so great to drive again! Thanks to everyone for letting me vent on this thread throughout the last 10 weeks!
sorry to hear about everything you had to go through but happy to hear you’re back up and running.
If it were me, I’d submit this to small claims court. Long ago I got tired of trying to figure out who is denying what and for what reason. Far easier to pay the filing fee and have them lay out their case in front of a judge who in my experience, don’t put up with handwaving about how things happened. Make them show how what you did caused the differential case to crack. If you have pieces, there are places that could do failure analysis and determine if it was a casting flaw or something.
Your state/county should have good resources on how to get started. Typically you send a certified letter saying “pay me
this amount in 7 days or I will sue for that amount”. I am not a lawyer and this is not legal advice but maybe something to look into.
