Bearing noise off the clutch suggest throwout bearing:

https://www.rockauto.com/en/catalog/dodge,1989,daytona,2.5l+153cid+l4,1089389,transmission-manual,clutch+release+bearing,1968

Otherwise my check for bad internal bearings is driving on a highway and hanging the left lane near a barrier in 5th, putting some throttle into it to load the trans you will hear bearing noise if you have it. List below credit from a post by ILIKESHELBYS, this requires pretty much a trans rebuild:

A bad throw out bearing will be noticable when you are depressing the clutch, not when you're off the clutch.
I have a good feeling I have a bad input shaft bearing causing end play in the shaft.

Thanks for those numbers. I appreciate it.

I had an issue with my DD 2004 Chrysler Sebring Coupe (Mitsu stepchild). Started at about 130,000 miles. When in neutral (no clutch depressed) a whirling sound was heard, sounding like a bearing going out. Thought maybe it was the throw out bearing but like you said it would only make noise if the clutch was depressed. Turned out it was the clutch springs! At 180,000 I replaced the Chrysler clutch & flywheel with a Mitsubishi clutch & a Fidanza aluminum flywheel. Took it real easy for the first 500 miles to temper the springs. I sure as heck don't miss that whirling noise! :smile2:

A rattling noise in neutral is often referred to as "Neutral Synchro Rattle"

Changing fluid normally stops the rattle, especially with a higher viscosity.

The rattle isnt a problem, just an annoyance.

It's also recommended to overfill by about a pint.

This ensures adequate lube to the intermediate shaft bearing.


Thanks

its funny you mention that ive had my car for about 15 years and its always had that noise in the trans. I did change the fluid about 3 or 4 years ago and the noise almost completely went away, so maybe it is just the syncro rattle and not a bearing. I hear no noises at all when Im driving in any gear.

No worries.

Where the bearing runs on or off the clutch, when it is getting at the end of it's life it will rattle no-load off clutch, and then quiet when you load it on clutch. If it sounds like garbage on the clutch it's ready to explode!
