Front drive shaft rotational noise

Howdy all

I have a 2014 JK Sahara (60,000 kms or 37,200something miles on it)

Recently I've been hearing a really bad clanking and banging noise from the front of the car. It only happens when I'm offroading and the car goes on a side incline or at least when one of the front wheels is higher than the other one (going over a rock or whatever) It's as if whenever there's side pressure on the front wheels it makes that noise.

I know it's not my suspension because we have a lot of speed humps around my area and I don't here any noise when driving over them, or even going on a dirt road.

It only happens when the car is on a side incline. I will try and make a recording of it, haven't been able to yet. But it's really loud, so much so that last offroad trip my friend who was driving in front of me could hear it clearly (a distance of the length of 3-4 cars ahead of me)

Been to 4 garages, no one could find anything. So I decided to get under the car myself and see if I can find it myself. I banged pretty much everything with a rubber hammer and tried to move things without pushing the car of the jack stands. But found nothing. That led me to my second issue with the front drive shaft.

I'm just gonna link the video about the noise/issue:

https://youtu.be/DqPpJIjyRDY

To elaborate, the front shaft doesn't wiggle, as in it only rotates and it doesn't move side to side or up and down. The front side anyway, the back of the drive shaft that connects to the transfer case has a very small give when I push it up and makes a clicking noise, guessing the back u joint needs replacing.

I just wanted to know if the rotation noise is normal or not. I've seen some videos of people showing bad drive shafts/u joints but I'm not sure if mine is in the first stages of going bad.

I apologize for the really long post, I just wanted to be clear about the issues.

Thank you

PS: I don't hear any noise while driving at any speed, I do get a bit of vibration at around 50 mph but goes away if I go slower or faster than 50mph

If it only happens when side loaded it seems to me like it would be a ball joint, unit bearing or u-joint. A shop should have been able to find that pretty easily though.

Ya the shops I went to checked those and said they're fine. They also checked all the nuts and bolts to make sure everything is tight. I didn't get to check the rear parts cause it started to rain heavily. Tomorrow I'll check the rear.

I'll try to do a video of it tomorrow with my GoPro (completely forgot about it) and I'll put up the video.

You might check the torque on your track bar bolts.

I have an aftermarket track bar that has a tiny bit of play at one end and it clacks pretty loud sometimes when I go over uneven obstacles.

Get under it and have someone grab a tow hook and shake the crap out of it side to side. See if you can hear or see anything.

It could be the drive shaft. Inspect the slip joint boot to make sure it's not torn. If it is, you might be hitting your exhaust cross over.

Also check the CV joint near the transfer case. If you see grease flung up under the Jeep near that spot, you may hove torn the boot and the grease is all gone, wearing the joint.

In either case - you would need a new front driveshaft - and I recommend an aftermarket from someone like Adams Driveshaft.

BTW, it's a Jeep, not a "car".

Whoops. Went back and watched the video. I see you already have an aftermarket shaft.

I would check all of your suspension spots. make sure none of the holes has ovaled - like the track bar mounts especially.

Remove the bolts on the control arms and track bar and examine the insides of the bushings. You shouldn't see thread grooves. I would consider replacing all of the control arm bolts with a Northridge 4x4 Grade 8 upgrade kit and retorque everything to spec.

From your description, I am wondering if a control arm or the trackbar is moving slightly under stress and is making the loud pop or crack. It wouldn't happen under normal driving conditions, only under extreme stress on the suspension.

I humbly apologize for calling my jeep a "car" lol I shall move to punish myself for this transgression (aka no icecream for a week lol)

I will get the bolts checked when I get a chance but during the last service (2-3 weeks ago) I had the jeep service guy do a check and retightening of all the bolts but the noise persisted even after all that. But I will get someone to open them up again and check the insides as you said.

I actually had no idea I had an aftermarket driveshaft. guessing the jeep service center did it without telling me the last time I went for service. I was wondering why it's so much cleaner than the rest of the parts lol

I checked the CV joint near the transfer case, there is very small amount of up/down movement (very small) so I will get it checked. but the boot is fine and looks very new (new shaft i guess)

my guess is the trackbar or control arm, or something like that is moving as you said. I'd open everything up myself right now but I don't have the tools to make sure I tighten everything properly again.

Thanks for the ideas thought, definitely heading to the right direction. If I can find my gopro I'll go do a video to reproduce the sound and I'll post it up.

Cheers

PS: Nice to see another photographer on these forums

If you didn't know, then you don't. It just appeared to be different than a stock shaft from the video. Going back and looking at it again, I was probably right the first time.

Keep us posted.

Fyi, my front stock shaft has a tiny bit of play side to side up and down going into the transfer case as well. Curious I crawled under my brothers 4 dr and his front shaft has the same play. I also thought this isn't right. Apparently normal.

I'm happy to report that I believe I found the problem. Last place I would've thought of.

My front driver side bump stop is bent inwards (towards the engine), as in the metal part that is attached to the body. I believe when offroading or any movementthat cause the jeep to wiggle the bump stop kept hitting my springs. Gonna try and attach a pic of it so you guys can see as well.

Funny enough I came for a tire balancing and that's when I noticed the bump stop lol

Will need to visit a body shop so they can pull it straight. Will report back after I visit the body shop.
