On the back of the t-case. Is that supposed to be attached to a speedo cable or sender or something?
Only if necessary. It can be used with the Inchworm adapter to connect to vehicles that need the speed sensor...

I took a quick video as to why I call my self stupid. One quick look at the undercarriage would have answered my questions...

Marlin had a special on their oversized CroMo 30 spine output shafts, front and rear so they are on their way along with a gasket kit. Better to be safe than sorry...

That's a lot of slop.

Yes it is, kind of embarrassing that it got this bad before I noticed it...oops...
Maybe I'm dense, but isn't there an output shaft bearing in the t-case (pressed into housing) that needs to be replaced? Not just swap a shaft and replace the seal?
BTW, nice video. Very helpful with explaining the situation.
edit: read your post on page 1 where you mentioned about replacing the bearing...
With the fluid on the underside, I would recommend checking your t-case fluid level and refilling before you plan on making any relatively long trips.

You got it right Clint. Luckily, Regina is out of town for the next 10 days or so, allowing me to park the FJC for the time being. I'm hoping to get it pulled this weekend so I can rebuild/enhance it during the week.
Here is the link to Marlin's page for all the parts included for this upgrade...

Finally accrued enough time under the FJC to get the Inchworm out and free to clean up/inspect. Glad I ponied up for the cheap Harbor Freight tranny jack.
Fresh out of the mess, just a bit of overspray mixed with sand, makes for a nice and destructive compound...
Hit with some simple green and the power washer, just a bit cleaner...
The drain plug paste is pretty thick and tall, found one small sliver but mostly heavy paste...
Tomorrow, I'll break it down...

Got it open and broken down for the upgrade. Things looked good inside, nothing I could identify as being a problem but I'll be cleaning all the gears up for a close inspection tomorrow...
Since I broke it down, I had to clean things up and consider a color change. As much as I can appreciate the "Inchworm blue", if I had one of the blue FJC's, I'd keep it. One thing I can say is that the powder coat Inchworm is thick and stronger than any I've dealt with before. Sandblasting, the powder coat took it and laughed back so I had to resort to chemicals. Found some "aircraft stripper" and it worked well.
Just too many nooks and crannies, it took me half a day just to get it clean and ready for a new color. Here is the pile of parts that will occupy most of tomorrow playing with and trying to get everything back the way it came out...

looks like a puzzle on the table... but, i do like the yellow.

So, here is the pic of the Inchworm installed.
Took it for a test ride and the noise that started this process is still pervasive. I had my daughter drive me around while I was hanging out the back to see if I could better locate the origin of the sound.
Without a doubt, its coming from the rear diff, don't know why I didn't do this sooner.
So, the quest continues. I'll be tearing the rear end apart to see if its something other than the ring & pinion. One of those mysteries since I can't imagine doing it during the radically challenging runs at the Spring Tide Ride...

Hey Jerry,
Sorry to read about your continued woes. I would bet your pinion bearing might be shot. If the o/p of the tcase was sloppy, it might have radiated back to the pinion bearing, causing advanced wear. Try wiggling the pinion (yoke) with the driveshaft off and see if it's still nice and tight or if there is any slop.
Good Luck.

Good point and I did give it some attention. Clearly, I need to go through a more systematic troubleshooting process. At this point, I'm taking a blow today, sitting around being grumpy for missing the Exped thing...:whoops:
The process i have always used during something like this is to put it on the lift / stands and start it up and put it in gear to see where the noise is coming from. Keep someone in the seat though if you do this on stands for safety reasons ofcourse.

Agreed, it surely needed attention as does the whole rig. 5 years of abuse, its done pretty well all in all...

I have a parallel thread in the FJC section where LT of Metal Tech advised to check the R&P backlash via checking the slop in the driveshaft. He advised that anything more than 1/8-1/4" of movement meant the backlash was out and I would be in need of a new set.
Here is a quick video of the present slop...
In my eyes, its clearly more than 1/4" and its worthy of further investigation. Oh well, such is life in an expensive hobby...

Jeez, I think I have that much play in my diff as well, but it's a low mile FZJ80 diff. When I put mine in it looked perfect.
I guess you've got to pull it and take a look, very depressing...
