Throw Out Bearing? Please Help!
I recently installed a new remanufactured ZF tranny. I bought the tranny from a local transmission shop, but installed it myself. Wishing I didn't now because I'm having a problem and looks like I'll be taking it out again. Also new LUK Flywheel, Clutch, Pressure plate, pilot bearing, and throw out bearing.
On short trips this problem doesn't occur only if I run the truck 20 miles or more and didn't start till about 1,000 miles after the tranny was in.
The problem is a squeak/grinding noise that is rotational and changes frequency with rpm. The only time it doesn't do it is when I push the clutch in.
I thought maybe pilot bearing, but if the engine is running no matter on clutch or gear the flywheel pilot bearing will always be turning around the input shaft.
I also thought throw out bearing, but I thought it just slides up and down the shaft and doesn't rotate.
Any suggestions please! What am I not seeing?
