True but it keeps the input shaft concentric with the crank rotation as the clutch disc can slide around
So a damaged pilot bearing can cause a damaged input shaft bearing so agree on what makes noise now but not necessarily not related to the pilot bearing

|Water Dog||It shouldn't be the pilot bearing because with the clutch disengaged, it's not turning. I would suspect the transmission input shaft bearing as others have said.|

|MudJam||Haven't taken trans out yet. But wanted to know which trans bearings to replace .|

|Digger84||JP mag had some good photos of inside of that tranny on a 2 part story called five-speed overhaul late-model manual rebuild you might google and look at pilot bushing and input shaft tip photos|

Input shaft/bearing likley but 2 questions
1) did you inspect or replace the pilot bushing/bearing in the ass end of the crank shaft?
2) when you were installing the tranny did you slide/wiggle it all the way home so bell flange all the way against rear engine flange or did you use bolts to pull it home?
The bolt pull method can be bad although some get away with it but those components were not designed for axial load
Bolts without heads (with slots where heads were removed for removal easy with screw driver) used as guide pins when sliding/wiggiling tranny home is ok but risky to drive it home by tightening bell bolts

|MudJam||So I also have that noise. What bearings in the trans do I need to replace ? I plan on changing my clutch and want to change them while it's out.|

|Toren||Well I replaced my whole clutch and flywheel, and the sound is still there. It's not like a way loud grinding sound, I've been told its just the gears in my transmission moving when it's in idle position. And I've been told that model is just loud with that transmission. Everything shifts smooth, it's just that sound when I idle in neutral. I'm hoping it's not a transmission bearing, cause I don't know how to fix that. I'm wondering if it is my bearing, would it have been caused by me having a 3" lift with the 33"s and not gearing down yet? Like I'm pushing too much on my engine? I kinda thought about that. And when I do gear down, I don't know if should do 4.88 or 3.66 gears? I don't want to screw up my engine. Btw I'm new to this jeeping stuff, so I need some help. Thanks!|

|SurfKaster||Is it a grinding sound or does it sound like rolling pin? The nv3550 is notoriously loud. Mine makes all kinds of racket when the clutch isn't pressed in.|

|R u s s||Hate to tell you but that is the transmission bearings. The throw out bearing would be opposite of you issue. (Grind when clutch is pressed in) I would drain the oil see how much metal is in it. If it not to bad just refill with oil and add some lucus to it. If the noise isn't to bad I would continue to drive it till you find a good replacement or rebuild it.|

Clutch or transmission problem! Help!!
Hey I have 03 tj, and I have been having a light grinding sound when I sit in neutral, but once I push the clutch in it goes away, thought it would be my trow out bearing or input shaft bearing, so I replaced my whole clutch, flywheel, and did my oil pan gasket and main rear seal while i was under there. put it back together and that sound is still there! Could it be a transmission bearing or something?
