crown sye seal?

last week i installed a crown slip yoke eliminator on my np 231j. i noticed that the new output seal is leaking a bit.. a drip or so every ten minutes.. it only leaks when driving. this particular kit the bearing snap ring seal etc. were already installed in the tailhousing when i purchased it. the yoke has been torqued to 150 ft lb. is this a common issue? anyone else have this issue? and if i am to purchase a new seal does it have to be from crown or is it the same seal as stock?

Are you sure its from the seal and the oil is not slipping through the splines and coming out around the bolt?

yes. the nut and area around it are dry.. i have been driving, cleaning it up, driving and looking very carefully. when installing i put the little rubber star washer and took the extra measure of putting black rtv on splines and nut. i am very confident it is coming from between the yoke/shaft and rubber sealing surface. i just dont understand.. seal looks good.. is plyable like a new seal should be... spring thingy is in place and looks good. im pretty sure seals dont "break in".

Possibly just a bad seal. Is it installed 100% straight? Did the yoke surface where the seal rides look good?

I can get you an industry number tomorrow if you need...I think I wrote it down somewhere at work. They're not a regular stock one, but can be found at most auto parts stores if you have the industry number.

thank you responses. im deffinately gonna buy a new seal... i am starting to think the one i have is in backwards... the little spring elastic thingy is facing outside the t case. every seal i have seen they are facing the oil side/inside. does anyone know? i wanna be sure i am installing the new seal in the right direction.
