I have since installed the T-case drop, as you will see later in this thread. It solved the problems I had in the "UPDATE" below. Suspension feels wonderful, the Jeep handles obstacles beautifully. I also removed my rear trac bar. Didn't notice a big difference on the road, but I can see better articulation off road. Removing the rear trac bar seems to be all benefit, no downside (for me).
After driving to work and back (hitting 75), I started noticing a slight vibe between 20-25mph. I also noticed a strange feeling/sounding "rotation" when I either lay of the gas, or clutch when travelling above 35mph. I can hear what I think is my drive shaft spinning and it sounds like there is some friction.
I plan to grease or possibly replace my U-Joints and possibly install the T-case drop. SYE and new DS would be nice, but not really interestied in dropping the coin/spending the time. SYE seems to be overkill with 2.5-3" of lift. I will post before and after shots of my DS angle if I decide to go wth the TC drop.
The time finally came to install my ARB Old Man Emu (OME) suspension kit this weekend.
Running stock leaf springs and cheap replacement shocks on my 1989 YJ (2.5L, soft-top). I installed the ARB Quadratec Edition Stubby Bull Bar with M8000 winch last fall which casued significant sag in my front end. Researched lift kits, narrowed it down to OME and BDS very quickly. Ultimately decided to go with OME.
Measured day after lift, may settle some.
Front: 2.5" - 2.75"
Rear: 3" - 3.25"
(4) CS036R OME leaf springs. These are the HD, 5 leaf varietal.
37R's in the rear were considered. I run a soft top/no top, and have no accessories in the rear.
(2) N33 OME Shocks, (2) N34 OME Shocks
(custom bent at a local spring shop)
(6) .5" x 2.5" x 7"
(2) .5" x 3" x 7.75"
These were all way too long. I had to go back and cust them all down with a Sawz-all, which was a bit of a PITA. Could probably get away with 1 - 1.5" shorter on all 8 U-Bolts.
(4) MOOG SB 373 Rubber Bushings
(8) MOOG SB 376 Rubber Bushings
I went with rubber bushings because (a) I got them for free - I used to work for Federal-Mogul, the manufacturer, and (b) I was told they would be smoother and quieter (by Dirk at DPG).
(1) MOOG SSD107 Heavy Duty
(2) 3-ton jack stands
(1) 2-ton bottle jack
(1) Floor Jack
18V Dewalt Impact Drill
1/2" Ratchet with deep sockets (3/4", and 7/8" were most used)
3/8" Ratchet with sockets
Cheater bar (1" x 18" steel pipe) - COULD NOT HAVE DONE IT WITHOUT THIS!
Steel pry bar (probably the 2nd most important tool)
Total installation took ~8 hours (from start through clean-up).
My Jeep is a very rare and endangered YJ - it's rust free. This helped a ton with removing bolts, but the U-Bolts and frame side (not shackle side) spring mounts were VERY stubborn. I hit everything with PB Blaster three times - 2 weeks out, 1 week out, morning of.
Started with the rear, removed springs and shocks, realized there was no way I could get my Moog bushings into the springs using the "threaded rod with two big washers and two nuts" method. Brought the springs and bushings to a local shop, had them pressed in for $44 and a six-pack. NOTE: The guy at the shop showed me the 20-ton bottle jack he broke in the process. He said it was a HUGE PITA installing these... Remember, these were MOOG rubber bushings, not the poly bushings most people use.
I would heavily reccomend taking your springs and bushings (especially if you are going rubber) to a shop and have them press them in. Save yourself the headache.
Installed the springs and shocks, did the same to the front, and we were done.
Rough Country installation instructions are pretty helpful (although we didnt consult them).
Shackles: 75 ft/lb
U-Bolts: 90 ft/lb
Before I could torque the U-Bolts, I had to cut them all shorter with a Sawz-All. Deep Sockets were not deep enough (and didn't want them to be the new "low point" on the Jeep).
Took the Jeep to a local trail the next day (yesterday). The first obstacle caused LOTS of metal on metal sounding popping. I pushed through and never heard it again. Not sure what it was - perhaps just "stuff settling".
Still bumpy as hell on trail (yep - it's a YJ), washboard handling was MUCH improved, road ride is similar to stock. No vibrations at 75mph (did not use the OME T-case drop kit -PM me to purchase).
Very happy with the new stance - 31" Duratracs next!
