Mopar LCA swap

[jmcdtucson]

Where is the best place these days to order the longer Mopar LCA and get them quickly? I've read a lot of the older threads but couldn't find some of the suppliers that were mentioned.

I have some concerns about when/how to tighten the LCA bolts/nuts:
If you tighten at fully extended position - the silent blocks will be at the stress in normal driving position and even higher stress at fully compressed position.
It looks that the best way to tighten is when car is at normal driving position (when resting on its suspension). This way it has to flex only half way (+-) during compression/decompression arm travel and should last longer due to lesser stress.

How did you tighten yours?

I used the factory tightening procedure while Fully on the ground.

I don’t recall the torque figure you go to or the degrees the nut is rotated after reaching that torque figure but I chose this method. My 150lb-ft torque wrench would not go high enough so that’s also why I chose the factory tightening procedure. Just use a marker to mark the nut and mark the frame however many degrees after, then hit it with an impact a little at a time to creep up on making the lines match up. No bushing binding.

they are a VS of this forum

forum versus what?

I think one of their shipping centers is in the DFW area.

I read somewhere about mopar parts in Dallas. I did extensive searching on google maps and could not find them so I thought maybe they weren't around anymore, since I had been reading old threads.

Well anyway I'll try to find them again.

He meant a site sponsor, just use the code @FlashGordon posted and you're good to go!

Yeah, I just maxed my 150 ft lb torque wrench than went another 45 degrees w/ my 2ft breaker bar, probably a bit over 190 ft lbs but close enough

Ordered a few weeks ago from https://www.allmoparparts.com/catalogsearch/result/?q=68322798AA
Free shipping code was: FS2020
Ordered on a Wed night and had them delivered that Sunday. Total was $61 for both LCAs.

I ordered today, free shipping code still worked but it invokes "ground" shipping instead of the expensive FedEx option. I'll report when they arrive.

Edit- package arrived Monday Nov. 9, shipped to Texas from New York.

I got the Mopar longer arms. I just couldn't get the right angle on things to break the nut loose. I went by my local shop after work and talked to a mechanic that does the work I don't have the patience for. Played on my phone for a bit and $50 later they were on. I have to get it on the freeway to see how it tracks at speed in the next couple of days.

Love this thread - very helpful! I have two questions that I don't think were answered already:

1 - do you need to get a wheel alignment after installing the longer LCA's? I just had a RC 2.5" lift installed recently and paid for an alignment afterwards. Would anything other than castor change?

2 - I'm in Canada and am looking for the best place to buy the Mopar LCA - is a dealer my only option that won't kill me on duty/taxes/shipping?

Thanks in advance!

Most alignment settings are not adjustable so no need to pay someone to do it. The caster is set by the length(s) of the control arms. Actually if you buy a lift kit containing adjustable control arms then you could adjust the caster but with the mopar LCA you are stuck with what you get. Camber is built into the front axle, can't be changed. Toe-in is not really changed by the lift itself but is the only setting that is easily changed. Whoever does the install for you can easily do the adjustment to center the steering wheel.

Your toe setting won't change with just a control arm install.

Can anyone verify the torque specs?

190 ft. lbs. on both LCA bolts.

Just got mine on my stock JLUR and it drives amazing now. It’s like a totally different jeep.

So just to see if this is an issue remedy for me or I'm I just paranoid? First time jeep owner. I have a 2021 2 door Rubicon. Drives fine up to 50-60 mph. Steering isn't as tight as other vehicles I've had before. at 65 mph and up it's almost scary to drive as the steering wheel has about 1" to left and 1" to right of play before it actually responds. So at interstate speeds it's like I'm always correcting and recorrecting as the road turns. I can actually wiggle the wheel left and right and it doesn't turn. Is that normal or will the LCA improve, or remove what I'm experiencing?

Yes, these will help remove some of the "twitchiness" you're experiencing by getting your caster to where it "should" be. The LCA's probably won't do anything to remove the play in your steering.

I don't doubt when people complain about the play in the steering, especially those who've never driven Wranglers before. My son thought so too when I bought my 2018. But after awhile, he didn't notice it anymore. It never bothered me as I had owned plenty of older Jeeps and the JL seemed much better. The steering design isn't the best (especially if you've been driving vehicles with rack and pinion steering), but it is more robust for off roading, which is probably why the Wrangler still uses it.
