I had to get up early this morning to go down state for a funeral
had time on my hands waiting for my wife so I figured I'd give the img code a try guess it works

[okcrawler]

Hey, I was wanting to try that also. So, I hope you don't mind if I borrow your thread.... :)

For those of you interested in how TT is going to do a front only output mod, here's something to look at. This is the output shaft from the Sami transfer case. To your left is the splines for the rear output flange, to your right is the spines for the front output disconnect collar. In the middle is the coupler for the high/low range gears......

And to test the multiple post thingy, Here is my rock proof front drive shaft that I built last night sitting next to one of my old, VERY used ones. :D

P.S. - The main body of this shaft is 1-1/4" 1018 bar stock! :rasta:

No body asked me, but I gotta put in my $0.02 here on this rear output disconnect deal. I think this is a Questionable idea at best. I mean, you are putting all the stress on your front end - yes, those vulnerable Birfields. It seems like even if you didn't break one, you would be fatiguing them every time you use this option. I think it is a Very Innovative idea - another score for Brent & Trail Tough, just have to question it. Kinda like biological weapons - sure we can make 'em, but Should we?

Like I said - I know noby asked me :D

By looking at the TT Disc brake set up which uses the subaru calipers- I can see how easily cutting brakes could be installed which would compliment this rear Tcase disengage. However The birfield:rainbow: problem is still there.


wait..... I need the BIG Suzanna now.....

So with that setup up front it is viable and understandable....

AH! Brent's plan is Revealed! :D

Since I've been in this sport I've see SO many questionable things....
Such as:
Full float 26 spline Samurai axles... why??
Hybrid Tracker/Samurai axles... why why??
Z-link (as advertised to reduce/remove bump steer)... yea right
BIG drop link shackles.... just scary

And the J@#p guys are even worst..... I can't count how many time we've drug a broken 35C out! Yet someone will still put 38s on one!

However, everyone's circumstances are unique. With my Dana 44 front axle, I would not be afraid to run front only out of the T-case. Not to say it's indestructible, because I have killed a 297 joint, but it is avoidable with a little caution. Frankly I've just got tired of arguing... They'll figure it out sooner or later..... ;)

Anyone can be a skeptic.....
I like new ideas.. I've got the one's that worked :) on my truck and a box full of the others :( in the garage :rasta:

ROTFLMAO!!

Oh Man, that one has go to be the BEST!:rasta:


You won't hurt a D44 front with the "FrtWD" option, but have you ever seen the gear that drives the front output shaft on a Samurai t-case? :nuke: Like you said, let 'em figure it out:)

I'm glad your going to guinea pig the Klun in front of the Sam case. I was really concerned that the case could not handle the GRSII when I installed it. I have been very happily surprised! However, I'm rather skeptical that the case can handle a 4:1 going into it. I believe the key to it's survival so far is the divorced mount (especially after seeing dual and tripple case setups break transmissions and bell housings :nuke: )! I've become a big fan of the rubber mounts, so I'll be real interested in how your project goes together and holds up.... :D :D :D

I'll sit quietly, watching and learning..... Well, maybe not too quiet... :rasta: .....

[0ILBURNER]

Yes I had my reservations about that also. But I have Seen a sam t-case hold up to V-6 power in an S-10 pickup (weight), as well as the various V-6's (even a V-8) people shoe-horn into Samurai's. Anyone who has been on the trail with me knows I'm not exactly one to "rawhide" his way up an obstacle. This does not answer The question, though.

Will it hold up?

We'll have to see, won't we? :D


Needless to say, though, I will be carrying Plenty of spare parts!

[okcrawler]

Yea, I have changed a T-case in 20 min. I don't know if I would go as far as considering it a tril repair though. But, on out of town trips I do have my trusty 4:1 ready, back at the truck ;).

What gears will you be running in your Sami case?

Stock, and 5.29's in the axles.

.....TT setup does look interesting but just my o2 seems like just another stress point to break.:smokin:

[Rockrat]

Hey okcrawler shaft looks good but notice the new one has far less spline than the old one reason?? just cureous:smokin: :smokin:

Yea, a couple reasons.
1 - I have twisted two long ones (yes they are 1/2 ton 1-3/8x16 spined shafts!). When that happens all hell breaks loose, well mostly they lock up in the splines and rip the xfer case loose on the next bump! :D The first one happened at Moab, and we had to chain the drive shaft to the trailer and use a HighLift to separate it!

2 - I got rid of the :barf: Shackle reversal so I don't need all that travel any more. Of course, the small one still has about 2" more travel than a stock Samurai... :p

That counts as another lesson learned the hard way... Exposed splines are BAD - if they get damaged stuff stops working :rolleyes:

[Rockrat]

That does make sence I was toying the idea of going square stock for my front shaft seeings how its trail only vehicle but it all depends on how much cash I have left after I get a cage from fatkid:rolleyes:

[Trail Tough]

Hi Okcrawler, Rockrat, and Oilburner -

I guess I have to answer a couple of your wise questions. Do a SPOA on your buddies Samurai, use no steering correction whatsoever ie; stock draglink and see how bad your bump-steer is and how it drags along the spring on the passenger side as well. Then put a Z'd-Link and you will find it works much better - not as good as knuckle-over, granted, but there are plenty of lower budget builders - that is why.
Regarding 26 spline full-floater axles - first off one improvement we have made is that it is a chrome moly axle shaft, stronger than the originals. As a matter of fact, we have sold many and haven't had to send a replacement yet! So I assume none have broken. Next benefit is that alot of people like to flat tow and it is alot easier for the ol' boys who don't want to crawl under and disconnect their driveshaft for long trips. So there is your 'why,why".
Front wheel low option - 2 reasons, for momentary use for repositioning without forward motion for a better line. A life preserver option so-to-speak. I am not talking about trying to run a trail in front-wheel drive. Another benefit is once again, the flat-tower. The rear output is completely disconnected from the internal transfer case therefore no need to select neutral in the t-case, which would spin the front driveshaft and no need to unbolt the rear driveshaft to avoid that circumstance. I have also driven out of the trails on more than one occasion on the front axle with the rear driveshaft removed with a crashed R&P in the rear - 6 times to be exact (before we figured out our Hybrids with a larger ring and pinion were so much stronger and have not broken a rear R&P since). So, 6 times being able to drive home on the front axle only from various levels of trail obstacles tells me that momentary use of front-wheel drive for repositioning is more than likely not going to be a breakage issue for the transfer case because I have used the transfer case in this way - although I haven't tried to pit it against some overweight Jeep axles. I prefer to design from experience as opposed to mere speculation. So there you have your "why, why,why's".

[Rockrat]

TT I comlpetely understand your point and i guess because where I wheel Geographically, that option for use has never come up allthough I aplaude anyones vision to try and make something better I guess I may have been thinkin outloud. Ya know what they say if you build it they will come so..( Keep on design a quality product)

[okcrawler]

Point taken Brent....

Please understand, I'm not knocking these products. I understand all of them have their applications. Believe me, I have a friend who lacks the ability/skill/knowledge or money to install Dana axles. However, he still wants to run 33"+ tires and go the same places I go. Most of the time I just don't know what to tell him, except what I know. From my experience, I installed a GRSII and 33" tires with a stock EFI motor and it took me less than an hour to destroy two stock axles :nuke: . Unless someone can make those axles out of Kryptonite, a 26 spline axles would not last me more than one trip to Disney :D... Along that line, a bigger ring and penion does not save axles shafts. Being the engineering type I am, I set out to put numbers to my experience. Based on information extrapolated from Moser Engineering's alloy shaft data, places a 26 spline axle good for 3,576 ft-lbs of torque. A stock Sami motor with GRSII and stock R&P with locker is capable of 3,900 ft-lbs of load. For my case, and several others (non Sami) I've found this data to be surprisingly accurate.

With all that said, everyone's condition is different. Most people don’t run their equipment as hard as me, and most don't have the severe terrain we play on. But, when I'm feeding out my $.02 worth, I have to assume the worst…… ;)

(For anyone interested, the full axle chart and torque calculator can be found im the Tech section of Oklahoma Rock Crawlers web page)
