Transmission/Clutch Noise, any help?

Fuhaxian said:

I can't catch a break at all. I recently got my clutch replaced due to the clutch springs falling out or something along those lines and I opted to get OEM replacement since the last one survived for so long. I'm about three or four months since getting the new clutch and about a month since the new clutch I've been experiencing this sound: https://youtu.be/lY2GIQ252OM

2010 Jeep JK

This is what I'm experiencing.

Only starts ticking after driving approximately 30 minutes.

Ticking goes completely away when I push the clutch in.

Once it ticks, I can stop the sound for a few seconds by pressing the clutch in, but comes back.

Ticking sound is louder when the clutch is slightly pressed, "ride the clutch".

Ticking sound can be hear in low RPM's when accelerating but is probably drowned out when I start to hit upwards of 2kRPM

It is rythmatic, increases and decreases with RPM in idle.

It sounds almost like a card in a bicycle spoke.

Clutch is brand new from about a few months ago and this sound never existed beforehand.

I can't get the shop to diagnose it because of work hours and I don't have enough time to drive it around to get the sound to replicate. The sound is on-going and once it begins it doesn't stop unless of course I press the clutch in.

A side note: My slave cylinder is going out on me. I have no idea if this could potentially cause the loud ticking sound.

Besides the sound, the Jeep drives normal. I have no issues at all besides the transmission occasionally popping out of first which I found out to be a common issue for 2010 Jeep JKs

Sounds like the throwout bearing. First time I had my clutch replaced the shop didn't replace it. Had to go back to the dealer to get it taken care of.

Had my throw out bearing replaced twice and it came back both times within a month or so. Jeep has said it might be the input shaft/ bearing causing the issue. Frustrating for sure since I am not under warranty.

This is what my throw out bearing sounded like. it seems similar... the dealership replaced the entire clutch assembly and throw out bearing under "good faith" after a bit of resistance as it is a "wear item" and not covered under the factory warranty My jeep had <15k miles on it, and was about 1 year old.

So why didn't they replace the pilot bearing (~$18 part) when they had everything open down there. That's the time to do it especially when they replaced the TOB twice.

I've done a lot of research and every time I think it might be the TOB there's always several posts stating the TOB makes noise with the clutch pressed in. Someone mentioned potentially a pilot bearing. I don't know how the innerworkings of the transmission/clutch work to know enough of what moves and what doesn't move along with what sounds are associated to what entities. Unfortunately I was replacing the slave cylinder and now I have an issue of not being able to bleed it. So there goes my entire week trying to solve this puzzle. I think I might have misplaced the o-ring associated to the hydraulic line so looks like I'll be purchasing a new line just so I can source myself another o-ring.

I love my Jeep but sometimes I feel like it's not worth it or I should have been smarter when purchasing the right Jeep. I have a lot of miles on her from both the previous owner and myself.

sounds like a bolt holding the pressure plate has backed out of the flywheel and is hitting the bellhousing.
the moment you depress the clutch the entire flywheel and crank is pressed forward against the thrust bearing of the engine and the bolt clears the
bellhousing and stops knocking

have this checked ASAP, if that bolt backs out more it will destroy the bellhousing and clutch assembly

I was thinking along those lines too. It sucks but it could cause much more serve damage of not looked into ASAP

I haven't even thought of this, hopefully the shop will be able to check it out and let me know exactly what the issue is. I do know it's gotten worse since when I first noticed the sound. Hopefully she'll survive until next week.

Thanks!
