Slight “clunk” Noise

[Oneshotlucky]

I had the same noise OP. I haven’t heard it recently but it only started like a couple of weeks ago. Even very slight braking makes the noise for me. At first, I thought it was something rolling around in my bed or back floor area.

I’m not sure it matters but I also have some metal cloak parts installed. Just the front track bar and front LCAs though. I’ll poke around when I put the MC rear track bar on this weekend.

It’s such a light clunk/knock noise for mine and I could only hear it with the radio off but it was driving me nuts

I’m thinking I may have isolated the sound to the right front? Almost sounds as if it in the brake caliper? Almost like it loads when brake is applied then again the noise comes up again in reverse whe applied brake. Sounds like set and reset? I can replicate it over and over? Move for, brake, clunk. Move in reverse, brake, clunk!

Yea mine made the noise in reverse too. I also noticed that the noise occurred with or without weight shifting when applying brakes so your caliper theory could be the culprit. Any idea what would cause the caliper to do that though?

Front lower control arms were not torqued to 190lbs! In fact when I checked to see if they were tight I was able to turn them with one hand and the socket wrench! Cranked on both side to 190 and no more clunk! (For now). To think, I spent 2k on tires and almost 3k for the lift and tires to be installed by a well known and reputable shop here in AZ and still wasn’t right!? WTF is happening to the world today!?

Oh damn, I’m glad you got it figured out. Good thing I work from home tomorrow. I’ll check them out in the morning. Your shop wouldn’t happen to be All Out Offroad would it?

Lower control arms are to be 103 ft/lbs plus 145 degrees. That's the JEEP specs right from their tech info.
I believe the 190 is likely from a kit - and aimed at people who can't deal with torque plus angle.

It was definitely not at 145, turned with one hand and socket! Mines an aftermarket Metal Cloak game changer lift so went with torque specs from Mopar 2” lift spec sheet? Not sure if 190 will be an issue long term?? What do you think? It’s no prob to loosen and re-do if needed tho!

The 190 will be fine - it's still MOPAR specs for the 2" lift kit parts.

The 145 is 145 DEGREES after you reach a torque of 103 ft/lbs.
Torque to the 103 and then turn the bolt an additional 145 degrees of rotation - that's most likely well over 190 but I haven't actually measured it ............ yet. I plan on comparing when I strip this JT of mods to put them on the new one.
The control arms, upper, lower, front and rear, are torque plus angle. Torque to the spec mentioned and then turn the bolt another 145 degrees in the case of the lower arms.
145 degrees is roughly 2.4 "flats" of the hex head. A full turn is 360 degrees, turning the bolt 180 degrees is a half turn, and so on.

I had clunks from my adjustable and quick disconnect from endlinks. Make sure they’re greased.

Mine were dry and after greasing them the clunks are gone.
