I had my 2010 mustang gt clutch replaced with an Exedy 600hp clutch and Exedy lightweight aluminium flywheel and new pilot bearing and throw out bearing about 13000 miles ago. During the past month it is making a lot of extra rattling noises coming from the bell housing and a tap tap tap noise. When I look up into the bell-housing through the sight hole the clutch seems almost off balance. ( On a side not I do have ford racing hot rod cams so I do have a rougher idol.) I also noted a few small droplets of fluid which I wasn't able to identify at the site of the sight hole. I notice it most of the time when still at idle with the clutch pedal not engaged. I also notice a little extra engine/ tranny movement during hard acceleration. My thoughts are down to: Transmission input shaft, Springs on sprung clutch design, Motor or transmission mounts, throw out bearing being faulty? What advice can you give me?

You most likely have a clutch slave cylinder inside the clutch bell housing that could be leaking and causing the fluid your seeing. Or even the input shaft itself could be leaking. You have a bad/damaged pressure plate if the clutch looks off. If the noise is coming from the clutch housing sounds like you will have to pull the transmission out and have a look inside to see whats going on. Also if you have excessive transmission movement I would check the transmission and engine mounts for being bad.

Could bad motor mounts or transmission mounts have damaged any of those other parts? Also the movement of the clutch pressure plates spin seeming slightly off is relative to the normal sound of the engine hotrod camshaft sound as well. The car is driving and shifting normally other than that. Once disassembled if its the throwout bearing that is easy to replace. If it's the input shaft how difficult would that seal be to replace. If I find it is the input shaft could the clutch already be damaged and an upgrade to a 26 spline shaft clutch flywheel be better. I know I am throwing a lot at you here but would it make sense to go the 26 spline 8 bolt vs 6 bolt flywheel and if so would I also have to change the crank. ( Just forward thinking)

A bad engine or transmission mont isn't going to damage the clutch as far as the input shaft seals goes you would use a small slide hammer with a screw or a large pick to remove it. Putting the seal back in you would have to use something that would slide over the input about the same size as the outside of the seal to put in back in. As fas as splines on the input shaft for performance I honestly couldn't tell you.I dont really get into the performance end of cars. Your local ford dealer could be a great resource or a mustang forum for that kind of info.
