Clicking sound when going under 15mph

I am getting a weird clicking/knocking sound when coming to a stop or going under 15mph. There is under 5k miles on it. I upgraded the wheels to 35's and lifted it 2.5" almost immediately after purchasing the vehicle (under 100 miles) so I didn't notice the clicking beforehand. 4 Wheel Parts is telling me it is stuck in 4 wheel drive, because when they put it up on their lift, all four wheels spin in 2 wheel drive (which jeep is telling is a new feature on the JLs). Jeep is also telling me the wheels are too big/heavy. Neither one of them seem to be sure as to what the problem is. I just want my brand new $53k Jeep that has not even been off road yet, to work properly. Please help!

A lot of guys, mostly with Rubicons, have reported a knocking noise after doing a 2.5" lift and large tires. After a ton of trial and error, most of them have attributed the noise to the pinion angle at the rear axle.

These Jeeps nowadays use those crazy driveshaft joints. And, I've heard that Dana has also gone to a less reliable ball bearing style pinion bearing setup (among other changes) to try and squeeze more fuel efficiency out of the driveline. Apparently the new drivelines don't play well with lift kits.

What model is your Jeep?

Do you have the Select-Trac transfer case by chance?

I was asking because Selec-Trac equipped models use CV joints on the axle shafts and I wonder if the noise could be coming from those? They will commonly click when they're stressed or failing.

WXman - I wanted to report that I have been hearing the same sort of noise you described. I have a Rubicon with the mopar lift and 35s. If the noise is due to the pinion angle at the rear axle, is there anything you can do about it? Is it likely to fail?
Prior to reading your post I attributed the noise to the lower control arm nut coming loose. When I hear the noise I get under the jeep and have to tighten up the lower control arm nut in the rear. I was actually getting on the forum to try and find out the specs for that nut cause I wanted to either replace it or get a second set to use as a lock nut.

Like for example would a problem like this potentially be fixed with:
1. 1350 HD Rear Drive Shaft with u-joints?
2. adjustable control arms properly adjusted?

I still haven't found the source. The Jeep dealership keeps telling me it's the space in the center of the wheel (even though they are lugnut centric). It doesn't seem to me like it is the wheel for a few reasons: 1) I dont hear it on all corners of the Jeep, 2) I only hear it when I am going slow or coasting, and 3) The Jeep would be off balance. They are fighting me hard on this, and it seems like it's because that is one of the only things that wouldn't be warrantied. I guess it's time for a third (unbiased) opinion.

I have a 2018 JLU Sahara with the same issue and the sound is driving me crazy. I have the Mopar 2" lift (which really gave me 3.5") and 35" tires.

Have you tried grabbing the draglink where it connects to the passenger side ball joint and rocking it back and forth to see if thats where youre getting that knocking noise? Mine does it bad. There is some videos on youtube and other sites suggesting that mopar shouldve put grease fittings on those ends and that wouldve helped. Im probably gonna try the draglink flip kit. Im on my 5th wrangler so i know mopar well enough to know that they will not be fast about accepting any responsibility.

I attributed a constant clicking sound on my Selec trac equipped 2018 Sahara. I thought it was that or the trac-lok that comes with selec-trac.

Well, all this time, it is the back window's lower horizontal seal rubber that needed to be lubbed. That rubber seal would create a clicking sound against the tailgate due to vehicle vibration.

I was certain the selec trac/ trac Lok set-up was responsible so I didn't second think it.

It is my 17 year old daughter that just started driving, that pointed to the tailgate.... Sure enough, a bit of synthetic grease silenced it immediately.

Just try it.

you guys with the low speed rear clicking and an LSD... do a search for "knock in rear with Dana 44", first link has lots of comments + sound clips and simple way to confirm source

2013 Rubicon Unlimited with 35’s and flat fenders. Mine started doing it about 2 weeks ago. I speed up to about 25 mph and release the accelerator and the sound starts. No sound while under acceleration. Here is a video of it. The only thing I found was that two sections of heat shielding had come loose. One was a tiny metal strap by the collector (fixed with hose clamp) the other was a larger piece that contours the body up. This one is attached by some kind of push nut on a threaded stud. At first I thought this took care of it because I could not recreate the sound as before but after some driving it came back. The exhaust was too hot for me to check it again but I will.
