How I ruined a pinion bearing by extending my diff's vent tube

the only way you could insure that the crush sleeve doesn't get over crushed is if your pinion yoke were getting installed at the same time as gears/overhaul kit with new crush sleeve or, using the pains taking FSM method that requires the use of a high end inch lb. torque wrench - a vast majorty of mechanics don't do this and really, most of the time, it's okay not to.
Amen to that!

Omg!!
I almost can't believe this!
I went out to the garage to fiddle around this morning and about fainted when I looked under the JK. The mess is all over the inner fender, wheel, tire, suspension, etc. Gear oil, pouring from the right side axle tube.
Can you say "d-e-f-l-a-t-i-n-g" boys and girls?
How about "d-i-s-h-e-a-r-t-e-n-i-n-g"?
I've had the Jeep back for one day since the overhaul kit was installed.
It would seem I was wrong about my vent line puking enough oil to grenade the pinion bearing. Obviously, it was something more insidious (like, my AXLE SEALS).
Now I'm stranded until I can limp this freagin' thing back to the shop on Monday morning.
Seriously bummed....

awe man, that's gotta be frustrating. just to make sure, you weren't seen a leak like this before getting your pinion bearing fixed, right? i mean, if you were, it would have been really noticable, or, so i would think. so you know, in order to change out the pinon bearings, you need to pull apart your entire front end - more than likely, the axle seal was accidentally damaged when pulling things apart or being reinstalled. unfortunately, it happens and i seriously doubt that this is what lead to your inital problem.

Woah, he doesnt use a in/lb torque wrench? I would have a serious issue with that myself. Back on the TJ days I blew my rear pinion yoke replaced it in y garage and since I didn't have an in/lb I took it to the dealer to have them check it. After the mechanic told me I got it in spec I told him I was thinking about getting a in/lb and which one does he use? Then to my surprise he gives me some BS about how he didnt have one but he could tell by feel. WTF? I felt like a cartoon character cause my face was red and steam prolly blew out my ears. I was told by an oldschooler back in the day to run like hell from any mechanic claiming to be a human torque wrench. I guess it stuck.
Goodluck getting it back on the road. Hate to see you broke down again.

Eddie, I'm sure you're right now that I sit and think about it. The seal probably got damaged/dislodged when the axle shafts got shoved back in.
Miraculously, my local stealer has a pair of seals in stock, $22 apiece. At least I'll have parts in hand when I can get my Jeep back to my gear guy Monday.
