I've had the rear upper control arm spacer for a while now. I need to tackle this in the next couple days.
I bent my tie rod playing in the mud though so I got to change that out as well. Good thing I got a couple laying around.

|Bigrigr||I dont really see the big deal with the control arm bushings myself...I swapped out mine a couple months ago, and could see no reason to install them any which way? The bushings have a square spacer impregnated into the rubber bushing, but the control arm bracket that they slide into has no slot or grove to line up with. I believe the square spacer is more stable than just round spacers when everything is torqued down. There is little to no way that spacer could slip or twist with the square shape, so i think thats why it designed that way. I know many people have talked about sending their new control arms back because they are not aligned a certain way, but i couldnt see any reason for this myself. Just make sure they are torqued to spec, as the bushings will walk around if they are not tight. I wonder if we dont have more of a problem with getting the proper torque on the bolts, versus the orientation of the spacers.|

|Hodgelodge||Any updates on this ? I do remember when I changed my rear upper control arm the bushings were installed 90 deg out, could that be allowing side to side play ? I know I'm REALLY reaching now.... any one|

|Hodgelodge||Thank you. I had watched that video before where he makes a spacer out of cutting boards. I'm at my wits end with this , theres got to be a way to make it drive better. Thats why I went with only a 2" , to avoid all this. All I really found was elongated bolt holes at upper rear control arm, I torque striped it after I put it together and was getting no movement. everything else back there is new.|

Hodgelodge, I’m running a 2 1/2” spacer out back with a 3” lift , it was a definite improvement. From what I read iro has a 2” spacer. It might be worthwhile looking into. It was easy to install, just a little pita getting the longer bolts in there and mine took a 22 mm wrench as opposed to the original’s taking a 21 mm.
There were a couple of good, older threads that delved into the spacers. I believe they were from 2015. Dude named tollmtn seemed pretty knowledgeable. Good luck!

|Hodgelodge||I've been through this too, still am. Changed alot of parts, only have a 2" BB, the addco sway bar helped, so did the adjustable track bar. However it still floats around, I'm interested in the rear upper spacer, I too have noticed a pretty big angle on the ball joint with even a 2" lift. That is my next plan of attack, how thick of a spacer are guys trying? I would guess with 2" lift- 2" spacer however no one makes one. I really don't know what else to try but its driving me CRAZY that I can't figure it out|

But with the coil rear in this situation itís the rear thatís sidestepping.
I may also find the rear upper control arm bushings are failing prematurely because my lift does stress them. If itís that Iíll need to reconsider my rear suspension decision.

I too fell into the trap of buying the cheap amazon control arm kits... wondering now if that's going to bite me in the end.
I originally bought my jeep in winter time and never really drove it before I did the lift, wheels and tires, rust repair, etc. (winter project)
When I first test drove the jeep before buying, it drove super loose but I noticed the tires were low on air and I assumed that's why it was driving goofy. It had the on/off the throttle wiggle in the rear end which is why I originally replaced the rear controls arms and upper A-arm. Those parts cured the on/off the throttle wiggle but not the drifting around on the road.
BDW- how did you determine if your drifting on the road is due to the front end or rear end?

, if youíre asking about mine, I replaced every suspension bushing two years ago as part of a complete mechanical restoration. After that it was tight and drove perfectly. But the obvious play in the rear now (After not many miles) has me questioning the parts quality. I sourced some of the control arms from Amazon because IIRC they were out of stock from Mopar at the time.
It just came on gradually and feels exactly like ďnormalĒ bushing wear, but at low mileage. I donít drive the Jeep daily, so it doesnít get a lot of miles.
Iíll report back on my findings when I get into it. My gut feel is buying parts online was a mistake.

I have some steering wander in mine as well. Iíve narrowed it down to the rear end. And hereís the thing, every bushing and all the control arms front and rear were replaced two years and less than 15k miles ago.
I think when I get back into it Iíll find some of those control arm bushings or the rear ball joint is shot. Which if true means the parts were junk quality. Supposedly all Moog, but Iíve been seeing reports lately of counterfeit parts floating around.

|Zrsnopro97||Thanks for the encouragement man! I know of a couple 4x4/Jeep specialty shops around maybe I will give them a call. I’m not sure if they do alignments in house or not but maybe they can at least point me in the right direction! I’m pretty happy with the ride quality and comfort of this Jeep honestly, it’s just won’t drive straight for the life of me. Feels like I’m driving a boat in water with the constant back and forth with the steering wheel to try and stay in a straight line. Any gust of wind or bump in the road and it’s going to go in a different direction lol.|

Woah now! lets not get crazy yet.... We install lifts and leave them on because we installed it for a reason! Ha Ha Thats like getting your wife new boobs for Christmas, and then deciding their too big. (no such thing)
It's to bad you dont have a qualified and trustworthy alignment guy, a good one can be invaluable with stuff like this. You need to find one that can think outside the box, because a lifted Jeep is a "custom" Jeep.T he alignment specs now become more of a direction to head in. But depending on the tires, wheels, lift, and air pressure, the specs your Jeep needs could be different from stock. Usually bigger tires need more toe-in to compensate for the greater forces acting upon them while rolling down the road. The lift and tires can cause drift/pulls to become more apparent from the added leverage on the suspension. This usually requires some trial and error with Caster adjustments. (IE-creative differences between left and right specs to "make" a pull that opposes a pull in the wrong direction), etc.
If you double check all your frontend and rear suspension parts and nothing comes up, I would say you need to take a roadtrip and find a guy that does lifted trucks on a regular basis. They are out there, but you have to look for them specifically. Offroad shops and 4x4 outfitters around you can point you in the right direction as well. Dont give up! The answer is out there. I DO believe that a nice driving WJ with a mild lift is achievable. Mine drives like a Cadillac compared to my last offroad machine.
