In over 300,000 miles and 18 years my old 1985 F350 never leaked a drop from any seal other than one rear wheel seal and that was after a 6 hour soaking in a swift sandy creek which took a 450 John Deere crawler to get back on dry land. In 23,000 miles I have already had a pinion seal and rear main seal leak (still have that one, but Ford says the "assembly lube" should work it's way out and quit leaking any day now). I'm afraid to look at the front seal.

She said it was out of warranty but she also said that Ford will authorize up to two repairs in which I must pay a very small percentage. I asked her what the dealer will charge to replace the seal (diff does not get opened up) and she replied with $250 dollars. With the amount of things "possibly" going wrong with this truck I will eat my Pinion seal replacement and save my discount for something bigger, ie, transmission, etc. The truck is a 2003 F350 that is running great after they finally figured out the bad FICM. Still not happy with any drivetrain problems 7 miles after warranty runs out.

My 88 bronco's seal started to leak at about 10K, fixed it myself, thought I would have to replace crush collar, but you need to put a heck lot more torque on the pinion nut to crush the collar, than you need to tighten the yoke to the pinion. Still own truck, 150K, and still working.
Anybody interested in a never (brand new) used crush collar for an 88 Bronc?

I looked at my 2 invoices and neither one of them have a mileage difference which is bogus because every day they would test drive it and the mechanic even drove it home one night 15-20 miles each way. Anyway, the first invoice said mileage in/out 35514 miles. The second invoice said mileage in/out 35550 miles. Both RO's were closed the same day they were opened, respectively. Something fishy going on at this dealership? Second time they had it, it was in for over a week but it doesn't show that on the invoice, how do I prove this to the field service rep?

Well,the rep is going to have to do some investigating.you cant because you cant get access to the repair orders.But in order for the tech to get paid for road testing he is supposed to punch in and out and document the miles that he drove on his test drive.He also would have monitored the readings that you engine was sending to your pcm with a WDS (scanner) which also would verify your milage if he had docked the WDS before he deleted the session.Im not sure if it still gives the info to Ford after deleting a session.
