SYE's
« on: July 11, 2013, 11:19:42 PM »
I might have to put the Atlas 2 on the back burner.  I've got to get the Jeep fixed so it's drive-able for long distances but I can't put a lot of money into it.  So I thinking that I'll do a SYE as a stop-gap.  I should be able to get a SYE for $240 (JB Conversions?) and a driveshaft (Tom Wood?) for $200. that should get the Jeep ready.  It's either that or spend $300 on renting a car.  I figure it's better to spend it on the Jeep.

So I've got a few questions.  How early is Early?  When you see SYE's they list 'Early' 231's having bearings on the sprocket that have to be removed.  Anyone know when the cutoff it?  Also the shifter rail length is different.  One's 10" and the other is 9" which requires you to cut the shaft down.

I'm pretty sure any YJ with electronic speedo is not early.

This is the unit I used on my '94 YJ...  It's Performance Off Road Center one, and I have yet to have any issues with it (Installed it at least 6 years ago), and it's $80 less than the one you are looking at.
'94 YJ 2.5L with 4" RE lift, Superwinch EPi9.0, FoMoCo e-Fan, SD30 and SD35 w/ARB-5.13, 165A alt., 33" BFG KM2 on 15" AR wheels, Sony sound system, Pavement Ends Hardtop, Hydroboost

That's what I figured.  That means I don't have to knock out bearings hopefully not fut anything.

Ah, I was looking at the OEM shaft price!

I always like JB's stuff.  The yoke they show seems to be shorter then all of the other ones as well.

i think there's also a cut/tap option which is cheaper and can be done without splitting the case and without taking it out of the vehicle, i cant remember for sure, just from memory.

That's the OLD Rubicon Express SYE.  Everyone refered to it as the 'Hack & Tap'. I don't even think Rubicon Express/Transamerica Auto make it anymore.  At one time it was cheap but now that HD are below $200, it wasn't profitable since theirs started at $99 but teh YJ was around $160.

what i liked about it was that you don't have to take the t-case out at all (again, that's what i recall - was a long time ago before i decided to get a D300).

its still only 27 spline though.  I saw 4x4groupbuy had the, for $185.  For that price I'd rather have a 32 spline on a 241 shaft.

So looking into what I'll need to do.  I take it I'll need locking pliers as well as snap ring pliers.  What are the ones you recommend.  I haven neither as of yet.

Craftsman is always good for just about any hand tool. Check your local big box store. They have snap ring pliers, or they did a while back I have not checked in a while.

What about the super short kits? Is the JB one of those? That way when you get a Klune you won't need to move the motor.  :wall:   :fya:
Scott~

Using tools you have not used in a while is like shaking hands with old friends. :nod:

i bought one that's reversible with various replacement ends and can do both (not sure if it's meant for both but i was able to use it no problem).

Yeah that's a slippery slope...

For what I need right now, the regular SYE will fit the bill.  I'd be able to drive the Jeep long distances without the noise from the mismatched/steep driveshaft angle at 70 mph.  Honestly, I'm making it a expedition vehicle out of it.  I don't really need, a lower gears.  Fire trails and gravel roads at most I think.  I need the 300-700 mile dependability more then anything else.  I've got a yearly trip to LA and now I have a trip to Delano coming up in a few months.  I'd normally rent a car but I can put that into the Jeep and then be able to do other road trips.

What I mean by slippery slope is if I do a Slim SYE, I've got to get a pulse modulator so I can get the speedo to read correctly.  The SYE is $100 more.  Then pulse modulator is around $100, IIRC.  Then do I get the 1.25" chain and sprocket set as well?  What about a 6 gear planetary since I'm already in there.  How about a 2Lo kit?  I have two months to have it road worthy.  The HD SYE's will pay for itself in the first trip.

The other problem, the JBC Shorty as well as TeraFlex's Super Short aren't in stock.

For fire trails and gravel roads plus highway use, the SYE will serve you well.  No need to spend more than necessary.
