Weird Vibration/Rattling

**cLockWise** · 05-01-2014, 01:15 PM

Alright guys, here is the back story. I took my car to have the following done: O2 Sensor bung replaced since it was cross-threaded on x-pipe. I had the clutch redone with the King Cobra I bought from MHS (10.5" as my car is a 2000). Bearings were replaced, I also added the UPR Extreme Microclick adjuster, MM Quadrant and the stock cable was used (I did not buy a new one, I used the one that was on the car). I also added in the LDC Freeplay Mod since I heard it was a good thing to do for our cars.
I have quite a bit of pedal vibration when I first put my foot on the clutch, just resting it before pushing it in, I can feel it vibrating my foot. The clutch grabs okay and seems to be okay. I notice a tad amount of chatter on the upper end, but nothing severe as this clutch needs broken in and I'm sure it will go away.
I've had to adjust this UPR FWA about 3 times now because it seems that it keeps "backing out". I marked the adjuster and drove it, but the adjuster never moved as I thought that was the issue. The marks were in the exact same spot, unless for some amazing reason it turned around that many times onto the exact markings... Which I highly doubt that.
The Vibration I am about to post below is of the car when I am driving and not using the clutch at all. When I'm cruising and on the gas you can hear this vibration and when I let off the gas, it goes away. I start back up it comes back. I notice this a lot more in 5th gear however, I can get it to do it in all gears depending on where I'm at. I can hammer 3rd and it'll start then let off the gas and it goes away. Hammer 3rd again same thing. If I do it through any gear it will start. I don't know what it is, but I'm guessing it is clutch related considering the car had 0 problems other than a bad clutch that was letting out up at the very top when I took it in to the shop.
Additionally, the TOB is a pile of garbage, it is squealing already. I'm not sure if these issues are ALL related to the TOB, if there is a clutch cable issue, or what.

Here is a video of this Vibration in action:

Pilot bearing??? Maybe the driveshaft got dented??? Dies ir vibrate at all when you rev it in neutral??? With or without the clutch depressed

I don't hear it in neutral when I rev the car. I hear a whining when the car is idling, but I'm pretty sure that is just the TOB. My buddy just sent me a text and said it sounds like the clutch fork from the freeeplay mod.

It's not driveshaft due to the fact it goes away when you let off of it....driveshaft is always spinning when car is rolling

Ttk said he thinks it's the free play mod. He said it sounds like the clutch fork rattling from that stupid mod. He said it was junk and he threw his away. Same thing I'm probably going to do.

What TOB did you use?

**cLockWise** · 05-01-2014, 01:58 PM

Was supposedly a FRPP TOB as that what was claimed when I bought the entire kit. I have a second FRPP bearing I bought it extra in case I needed it that I can put in.

Yeah I'd just stay with new clutch cable and no mod... if this freeplay mod is the only thing that changed, probably a safe bet as to where the issue lies.

Is the bearing retainer scored on the tranny? Lots of folks upgrade to the steel bearing retainer during a clutch upgrade, as the stock alum piece is easily scored and - I think - then causes the TOB to hang up a bit?

Just an update for everyone, the issue ended up being a junk TOB. I knew it was squeaking, and I had ideals in the end that it was a TOB, but I had never actually saw anything quite this bad to the point where it was shaking the entire clutch fork, the clutch, and then making the rattling noise that you all heard in the video. The FRPP TOB went in today, and the car is perfectly fine now, no issues at all. I just figured I'd update for anyone else who may ever come across this issue like I did.
