Help me find the noise/clunk

2012 JK Sport 2.5 lift on 35's

It's definitely a clunk/ bang coming from the front passenger aide area. I originally thought it was the door, but with 2 days of no doors the noise still haunts me.

It "sounds like it's behind the glove box are or the A pillR area. I've tightened all the bolts on the sport bar, removed the glove box door.

This noise/clunk happens on sharp bumps or a speed bump. It's not a constant road bump clunk, it's only on hard potholes or a sharp jarring bump.

I do see some movement on my right front shock lower bushing. Could that be causing the noise? They are rubicon shocks up front. Would the sound travel into the interior or the jeep?

I've tightening everything I could find. I even tried to tighten the are near the widnshield and wipers.

any idea ideas? This noise is driving me crazy!

When was the last time you checked lift fasteners for proper torque? Start with track bar... If it's even the slightest bit loose, dis-assemble and check the bolt and bushing.

Those rubi shocks SHOULD be still charged up and would be quiet in most cases, but you never know.

After this I would look very carefully at the suspension travel area below the Jeep. Look for any indications of metal to metal contact that would indicate something rubbing/bumping/contacting.

Good Luck. I hate noises like this too.

Passenger side shock lower bushing is definitely worn and has play in it. Pushing down on the Jeep by hand I can hear a banging from the shock area.

All the other bushing look OK.

I'm gonna order up some Ranchos 9000xls for good measure. I'm also going to order a new steering stabilizer . Anyone have any suggestions?

I still swear that the plastic dash is banging or something is lose behind the dash. Damn thing is gonna drive me crazy

WAIT!!

Wait until March 1 to order Rancho shocks- rebates! They "look" okay or are okay? You can't tell unless you remove the CA's and truly inspect them.

Buy the CHEAPEST stabilizer you can, you don't need a fancy or expensive one! If you're steering is working properly you don't need a stabilizer.

Behind the dash sound driver side? That might be the steering shaft. I used a grease gun with a needle tip and pierced the boot located under the hood and loaded that sucker up. It worked! Wish I still had the DIY link but I deleted it.

Upon further inspection is the track bar(?) that the steering stabalizer attaches to supposed to move extremely easily? By finger tips I'm talking.. the bushing looks smashed and worn out.

Rotating by hand I can hear a clunk noise like it's banging metal.

That's why I've been saying you HAVE TO REMOVE parts to properly inspect them!!!!
