Re: gees cost of factory d80 setup
I have gone round and round with Ford myself, back in the early 90's. We had an F-350 for a company truck, and it was back 19 times in 32,000 miles.
It seems out hubs locked themselves in all the time, and the front end would slam and then grind. Every time I took it to the dealer they claimed everything was normal and they couldn't find any problems. So one day I did like you describe, I ignored the grinding and drove it until it puked, then brought it in. They claimed it was not under warranty either, until I pointed to all the slips of my complaints. They had no choice but to fix it under warranty even though the time limit had expired. It turned out to be excess grease and the 1/4 turn throw of the Ford hubs, the grease had dried out and solidified (there was some rust as well), and the outer bearing heating up just a little expanded the whole mess and locked in the hub. When they took it apart it was completely toast from the hub to the U-joint.
Just because they never found a problem with the rear end doesn't mean there wasn't one, the fact you reported leakage is enough for them to have to address your current problem. Also, make them show you where in the contract it says the rear axle isn't part of the drivetrain.
Yes, they do make a Detroit for a D80.
