Well, the gooseneck is on hold, just got a call from the Ford dealership,turns out the whine that starts at 50 mph is from the rear differential. They said it needs an overhaul! They told me 1800 bucks, I said, not a chance. 850 for the parts, thats the bearings, seals, and the Limited slip clutch packs. I got on the FTE forum (been a member of that since 05), looks like it isn't uncommon for the diff bearing to go bad at 80-90k miles. I took it to another shop, 1100 out the door parts and all. I am ok with that, but that was trailer money, so I have to wait to get the trailer, hopefully in mid to late October.
*sigh, just got a call from the shop, the gears are damaged, replacing those makes the total around 1900. To go with a Jasper rear end, it was gonna be 3100, but I don't drive it enough to make it worth spending that much more. *
