Odd Clutch Engagement Noise. HELP!

[justprentice]

I don’t think this is a bearing noise, but maybe y’all have an idea. Upon clutch engagement in 1st gear from a stop, I get a new, strange friction point resistance and a noise that I can’t describe other than a "groan" but can document.

Had a new complete ACT kit w/ flywheel put in via a local Jeep specialist and it seemed to have some jutter from the beginning they they dismissed when I took it back to check it out. It still jutters a bit without throttle but 1/4 inch throttle, but now makes this sound and I have no ideas. HELP?

Your clutch needs to be taken back out and inspected immediately. I wouldn't continue to drive it.

I just messaged the shop.

I wanted to bump this back up, because the initial judder & noise has seemingly become a "groan" and I want to know what y'all think. I have a short YouTube video for reference.

@Actman I was told you’re on here by your team when I called today. Any ideas?

following this... my ACT clutch also developed this "grinding" or "rattling" noise about 2k-3k miles after install
however, I'm not sure if it's the clutch or something else that got loose and needs to be torqued like a bolt on a driveshaft (I'll admit I've been procrastinating to have it inspected but

definitely triggered my ocd) so tomorrow I'll see if I can have it put on a lift and have it checked out

the noise happens about 99% of the time going forward from a complete stop, there's been once or twice that it hasn't made the noise and I also haven't noticed it as much while on reverse

also I was on 4h once and when switched back to 2H it didn't make the noise like the first 2 times

I'll try to record it tomorrow to compare but what do you think @chevymitchell ? I'm suspecting it has something to do with the yoke of the front driveshaft since it was removed during clutch install and I don't remember it being torqued "properly" when reinstalling neither I might have stepped away for a minute while this was happening

I also contacted act customer service, @Actman, and was told that the engineers said since I wasn't hearing it on every shift/gear it couldn't be the clutch, I asked again if 1st and reverse being under the most load mattered and again was told if it was the clutch I would hear it every time it engaged on any gear

Eric forwarded the video you sent and I looked it over. I have a few questions so will send you a PM to discuss. There is no reason to stop driving the vehicle as chevymitchell suggests.

This sounds similar to a sound mine makes on occasion, except I have the OEM clutch. Does a little judder and sounds clunky. Not everytime I take off from a stop though.

Hey Dirk, mine is also doing the same on 1st, do you have an email I could send you a video?

@22Mojave

Couldn't see the videos you posted on the other thread, is it similar to the sound on the video from the OP of this thread?
