Hey there 'Mud,
Just finished the 'rite of passage' front end rebuild on my Vortec '60. (Chromo-Inners, Longfields, TRE's, Steering box, Hi Steer, Brakes/Rotors, etc./etc./etc. and all the bearings and seals)
During this work, I'd had a pesky 1-2 drop a day FRONT pinion seal leak from my axle, so figured I'd put in a new Eco-Seal Marlin Crawler seal, and re-fill with fluid per the FSM. Hopefully Bob's yer' Uncle and all's fixed.
Notably; Pinion felt good, lateral/vertical movement was less than 1mm (not measured, but tested by hand)
But, now, it seems it's leaking more. And, man... EVERYTHING else went in so well.
SO; I've been searching but unable to find a conclusive answer other than what I can intuit about replacing the inner bearing that the pinion gear/shaft rides on. My questions are as follows:
1) Does the entire diff need to come out to pull the bearings?
2) Could the torque of the flanged nut on the companion flange be the cause? (Torques were between 128ft/lb and like 300ft/lbs)
3) Is there any other issue I could have that one of you is familiar with that could cause this new leak now?
THREADS that helped me get this far:
RE: FJ80 with same issue
Any 411 would be appreciated!
Thanks
