Ok, so my admittedly bad driveshaft angles have killed my rear pinion
bearings, from the other post I gather that it may be a safe bet that
the t-case seals are damaged as well? Also, (my apologies for being
so damn thick) I really really don't get how/where any fluid my leave
my t-case after I remove the rear driveshaft. I will be changing it
this weekend anyway, but I will check the fluid level in the morning,
as the persistence of you and others that I should be losing fluid is
bothering the hell out of me.

The vibration that took out your pinion bearing also likely damaged the
bearing and seal at the end of the t-case. Not for sure, but very
likely.

Even with a closed t-case like my Dana 300, I had to change the rear
t-case seal as well as the pinion seal after my driveshaft exploded.

Basically just have a close inspection for fluid leaking out the back
before you put it all back together.

I would say unless you see fluid leaking from said seals, you're
probably still ok. I had a bad pinion seal from running high angles on
my rear driveline for a year before I was finally able to put in a
slip-yoke elminator and a double-cardan driveshaft, but my output seal
from the transfer case was still fine (of course, it ended up getting
replaced when I did the slip-yoke eliminator kit, anyway).

To tell you the truth, I thought it odd that everyone thought you
would lose fluid out of the transfer case as well; when I did my
slip-yoke kit and took off that tailshaft, nothing leaked then (of
course I was level and the jeep not moving, in my garage)... But,
after a recent trail run and seeing a wrangler with the stock
tailshaft bust, I learned it was true. He was trying to climb a
reasonably steep dirt incline, got on the gas WAY too much, and busted
the rear driveshaft. After the parts finished flying out (one landed
at my feet a full 30 ft. away), there was a LARGE puddle of t-case
fluid that had leaked out of the tail of the t-case where the
slip-yoke would have normally held it in. After some interesting water
bottle, bungie cords, and duct tape application, he was able to limp
off the trail in 2wd. So, I see your point, it doesn't look like it'd
leak out. Right up until the point when it does ;-). We just don't
want you to find this out the hard way when you're miles away from
home!

I have already learned alot from this group; it's been very helpful to
me in the past when I ask about doing one thing and everyone out there
"makes sure" I know another 10 things that might relate ;-). It also
helps out the lurkers who may have a similar question but aren't sure
they want to ask it.

Help me understand this:

I'm currently running with poor drive shaft angle (At the Transfer Case).
The angle at the pinion is ok or very close.

I just, a couple of days ago, went to home depot and bought about 200 pounds
of rocks in bags and put them on my rear side to weigh it down and help
break in the lift springs.

This action helped the angle at the transfer case. However, I still get the
vibration.


My questions here are:

How can one know when rear pinion bearings are shot, what tests can you do?

How can you know if part or parts of the transfer case is shot, what tests
can you do?

I've gone under the jeep and tried to find looseness by grabbing the drive
shaft and try to look for play or looseness. Can't find any.

Please let me know of any diagnostic techniques to understand the current
state of my drive shaft, transfer case, and pinion.


Thank you,

Bill
