Mopar LCA swap

[txj2go]

Yea maybe the fasteners had some effect. The bolt kept spinning on the washer regardless of torque... thats why i'm saying it was tough. One hand on the box wrench and the other on the torque wrench and then try to torque to 190 laying on your back pushing up.. I would like to think I'm strong, but damn that was tough..lol. Definatley helped when my buddy showed up to assist. I hope the ride is better and worth the cost and effort. I do plan to get a lift and hate the thought of removing the LCA's again to compensate for the lift height.

Torqing that much with a standard wrench is tough enough when you're in a good position, but for me to do it laying on the ground under the Jeep was not working. I ended up putting a small jack under the end of the torque wrench and pushing up on it. For the backup wrench, you just have to position it so it is pushing against some part of the body or the suspension. and actually for the front of my LCA I clamped a piece of wood on the side of the LCA and let the wrench push against that. Then I could use both hands to operate the torque wrench side of things.

i just installed a steer smarts track bar, tie rod and drag link, got it pretty well set but had the wife take it up to OK4WD to get it officially alligned. i considered replacing the lower control arms with adjustables before getting it aligned, but didn't. interesting enough with the OE control arms my caster is 6.5°.

That's interesting on the caster. Are the uppers stock also?

Uppers are stock.

OEs as in the mopar lift arms? Jeep not lifted?

yes, mopar original control arms and the jeep is not lifted, it's a rubicon.

i found it interesting that since my jeep is pretty heavy my suspension is sagged enough that it puts my caster into that "sweet spot" that people say JLs like.

What length are you guys running the control arms you guys with the mopar 2” lifts? Ordered me some adjustables just wondering what lengths got you guys to 6.3-6.5 on the mopar lift!
thank you

Many will ask how much lift you received from Mopar lift. From what I have read you should start at about 24 3/8s. But many have set at 24 1/2”. Center eye-to-eye.

Maybe I'll start with 24 3/8s and take it to an alignment shop. I have no idea how much lift I gained now. I've added bumper winch etc. and its been three years

anyone else with the mopar lift have any insight on the length they have their arms?

I got my LCA replaced with the 68322798AA on my stock Rubicon this morning, my caster went from 4.81/4.93 to 6.07/6.30.

With the new steel steering box and the longer LCA, it almost handles like a regular car… I’m happy !

Since the front LCA hole/bolt/frame had some play, we did a full front end alignment.

I was surprised that the technician’s computer had different torque specifications. In lieu of the 190 ft-lb as stated in the Mopar 2” Lift Kit instructions, he had something like 103 ft-lb plus 145 degrees, it was the first time that I saw such specs. His torque wrench also had the settings for the ft-lb and the degrees. So he had one beat when he reached the correct ft-lb and another one when he reached 145 degrees after the 1st beep.

Here’s some pictures showing the difference in length between the old and the new LCA:

I just ordered some mopar LCAs for my Moab, gonna be intalling the Teraflex 1.5” spacer lift so figured these LCAs will be a perfect addition.

I just put on the same teraflex

Just put on the same Teraflex 1.5” spacer lift myself wanting to swap out shocks as well with falcons how do you like the ride with the lCA

Another question.. so my new lca’s will help with wandering once adjusted correctly, but what would help with what I’m experiencing when I hit bridges or rough places in the road and the steering wheel shoots left or right? Sometimes it can be pretty violent. I have the newest steering damper and track bar from jeep. There is no death wobble, but it will definitely get your attention.

Is your front axle centered? I originally installed my lift with an adjustable front track bar and centered my front axle within a half of an inch. My Jeep drove fine but I was still experiencing bump steer. I finally got a chance to get back under the Jeep and perfectly center my front axle and no longer experience bump steer.

Anybody use the teraflex sport LCA? I have a rubicon JLU with the tereflex leveling kit.

It should be centered. Don’t have a lift. Just the new adjustable lowers.

Thanks guys for the very informative thread. 100 miles on our new Rubicon and I have just placed my order for these LCA to fix what should be fixed from the factory.
