new clutch now grinding noise?

Just got my clutch replaced at a shop in town. He said everything went good on the test drive. old clutch was a LUK upgrade and he said it looked fine when he removed it new clutch is a valair 06 ceramic-kevlar kit with a new flywheel. The problem is when in neautral and foot on clutch all is good but when i let off clutch there is a horrific grindind sound push in clutch and it goes away. When driving everything seems normal hits all gears no slipping no grinding into gears. The reason i replaced the clutch was shaking during takeoff in first and reverse. Any info is greatly appreciated

There is always the possibility that the noise is from the transmission itself. Did he drain the fluid, remember to refill?

With the clutch pedal depressed the imput shaft is not turning. With the clutch pedal out, you are turing the transmission internals. That is a common complaint when you have had a bearing fail.

I hope for your sake it is in the throw out bearing, but it does not sound like it to me.

A bad throw out bearing should only make noise if you are on the clutch. I don't think this would cause it either, but do you know if he replaced the pilot bushing/bearing(not shure which those trucks have)?

yes the mechanic first mechanic replaced both bearings in there with the ones from the kit. The second mechanic whom is a tranny specialist shop also looked it over and said tranny was fine and it was the clutch set-up. Bighunter how loud is the grinding? mine drowns out the motor inside the cab and walking outside the truck.
