i have a 03 durango output shaft seal was replaced on transfer case twice and the thing is still leakin any ideas what else can be goin on causing this?it is a 4wd.thanks

 

Welcome to DF
The seal thats leaking, is it on the transmission tail housing or the transfer box?

 

tailhousing of tranfer case where driveshaft goes in

 

Did you replace the Yoke and seal?


Also please post the motor of your Durango?

 

no didnt replace the yolk just the seal and it is the 4.7L.

 

Are using a dodge oem seal? The spring could be coming off the seal when installing it. Or there is a nick on the yoke of the drive shaft, I have also seen the yoke leak from the soft plug. Meanning its not seal,but the yoke. Here is what you can do, add dye to the transfer box and ck with a black lite to find the leak.

 

^+1^ A worn yoke will cause the seal to leak. Old seal put a groove in yoke causing it not to seal properly with new seals.

 

yea both of them that i put in were oem dodge seals.so i think im gonna try with the new yolk, will let u guys know how it goes thanks

 

New yoke and a new seal. Remember to lubricate the seal surface and the yoke surface before mating them to keep any abrasions from happening.

 

thanks i ended up replacing yoke,seal and universal and no more leaks.the yoke had a groove that was lettin the fluid leak.all fixed thank you guys
