leak i\'m lost

[TWO71]

ok if i park on a slight grade with front of truck higher than back my tranny leaks at the tail shaft now get this its not leaking out of seal its coming thur the hole in the drive shaft input splines any of you had this the only thing i can think of is i had the shaft made and i dont like the lenth that goes in the tranny maybe 2 inches needs another inch i think my guestion is if the shaft is not in far enuff would it leak is there an inner seal of some sort thanks also where can i get the rear end spacers you know the ones that sets it foward that is if we find out that i dont have the right lenth in the tranny thanks

sounds like your problem is the front yoke on the driveshaft..there should not be a hole at the end of the input splines for fluid to come out. If the yoke is two inches inside it should be past the seal and should be fine. there is only one seal.

actually you need the hle for your yoke to slide back and forth and yes the front yoke needs to be inside the tailshaft houseing more than 2 inchs,you will wobble out your bushing ect and have the leak that you have when you are to short... you want as much splined surface area (coverd by the yoke)as this is what seals the hole you are encountering

[alz]

also keep in mind that you need to allow the driveshaft to float in and out without bottoming the yoke on the tailshaft

I stand corrected dont\' know what I was thinkin! Yoke should be all the way except for 1 to 2 inches and hole allows air to escape allowing the yoke to slip easily. DUH

2 Types of yokes

1st Yoke with small hole in rear. Needs yoke tube seal [Inside tail housing]

2nd. No hole. Cap at rear can come loose and leak[Replace yoke or weld in place]
