SYE Seal leak
67 Attachment(s)
Just did the Ax5 to Ax15 swap. Had to intall the 23 spline input shaft myself into the transfer case planetary gear assembly. After everything is back together, now my seals on both front and rear driveshafts are slowly leaking. I dont understand, did I not torque the bolts down tight enough? What could I have done wrong or not done??

Should be 150 ftlbs of torque... if you are leaking, my bet is the seals are worn. Even if you weren't leaking before, you may have disturbed them enough to cause the leak.

Replace both seals and re-torque. Use a pipe wrench to hold the yoke while torquing.

The seals probably didn't seat correctly. My front one is leaking too after I did the SYE.
You said you pulled the shaft and replaced it with another right? I'm just assuming that you had the Tcase all opened up.
