THE LJ IS ALIVE AND THRIVING!
The day is finally here. The LJ is drivable, operable, and I am beyond excited about it.
The Revolution Gear Chromoly Shafts were delivered earlier today.

I spent about an hour or so pulling the shafts out, and getting the races pulled out of the axle housing..

THIS is the extent of damage, of installing Disc shafts on a Drum housing.
There's a difference in the Retainers, which I knew about and tossed in the back of my mind, and it ended up being a costly mistake.
(note, the retainer plate is SUPPOSED to be completely flat...)

100% the source of my shaft play & seal leak.
Got the new Revolution Chromoly Shafts lubed up & installed within a few minutes.
(this process is soooo much quicker due to Revolution shipping the shafts with bearings/retainer/seals pre-pressed. Mine were also pre-greased on arrival)
I still took some time to lube up the inner splines with Gear Oil, as well as saturating the outer bearings with gear oil before install.

Then I threw the LJ in the air one last time to double check torque specs on everything, as well as fill the differential fluid back up.
Once everything was triple checked, I FINALLY pulled it out of the garage for the first time in 8 days.

I drove it about 10 miles total (don't have a tag on it yet, so I can only do so much until I can make it to the DMV)
It surprised the hell out of me during those 10 miles.
Drove straight as an arrow. No pulls, no weird tendencies, it drove as good if not better than stock.
Return to center is great, and the entire driving characteristics were far beyond what I was expecting on the 'maiden voyage'.
Better than my TJ EVER drove, and my TJ drove great!
I blame some of the driving characteristics on how deep I decided to go when setting up the Control Arms, and also learning what I was ACTUALLY doing, and how it would affect the various geometries.
But, there's a few small kinks I'd like to work out before officially calling it "done".
I've got a front passenger brake that is making some 'scuff' noises (assuming I probably under-tightened something, or possibly some fluid on the rotor)
Also I have a driveline vibration around 65mph (blaming this due to the lack of an SYE)
I could adjust some rear pinion angle to alleviate the driveline vibes, but I doubt I'll mess with the rear pinion angle much until I get an SYE ordered and installed.
(if anyone wants to chime in on the SSYE vs SYE debate, let me hear it!)
For now, it's handling far beyond my initial expectations, and I am absolutely STOKED that it is not only back in operable condition, but with how great it felt on the road.
I went into this not knowing what to expect, and even surprised myself some along the way.
I'm no stranger to tearing things apart, but the anxiety of tearing TWO perfectly good things apart, and getting them back together is a shocker to me.
This one deserves a beer or seven.![]()
(if everything goes smoothly, the TJ should have a Track-Bar installed tomorrow, and hopefully will be in good driving order)
Congratulations man, I know how that feels and it's awesome!
I'm sure you noticed, but I threw some 3/4" coil spacers in the box with the bump stop extensions, just in case the springs sat different under the LJ than they did on the TJ. Not saying you need them, if you do it's not obvious from the photos.
Ok SYE, there's not really a good reason to go super short on an LJ...the shaft is a mile long. I have one because I bought it for the TJ. I do appreciate having a speed sensor and an electronic box to adjust rather than buying a Speedo gear, but at this point I'm pretty much done making adjustments.
However...doesn't the TJ have a SYE? I'd be kinda surprised if the shaft and pinion ended up in the right relationship with stock control arms and no lift, so you may actually need to take it off and go back to stock...have you had it up to highway speed since getting it rolling?
