hey guys. the rear oil seal on my transmission has been leaking and i guess i'm going to go to ford to try to find it this time. i went to a few different auto parts stores the first time i messed with it and none of them ever gave me the right one. the spring had fallen off of the original one and caused it to let go so i put the spring back on to get it back home and it is still holding to this day.. just leaks very slowly. anyone have the number for that seal and the nut that holds the pinion on the back of the tranny? i was told that nut is a one time use only nut, but i put it back on last time and already had to put it back on again b/c it fell off(thankfully it doesn't fit between the u-joint).. thanks guys.

while i'm at ford i'm going to pick up a fuel pump, dipstick tube o-ring, rear oil seal for tranny and nut, and a flywheel inspection cover b/c mine flew off somewhere and i don't feel like going to the junkyard. would rather get everything at one spot at the same time. sounds like work huh?

 

Sorry no part number but I had the same problem with the nut falling off and a small leak. I did get a seal at a local parts dealer but I think the leak might have been from driving around with the nut off. There was enough play between the yolk and the splined shaft to let the tyranny fluid by. When I replaced the seal I used lock tight on the nut and used a little silicone on the flange of the nut and the nut is still on and the leak is gone.

 

Hope this helps. Not sure what th kit has in it. May have to call
