92 YJ transmission noise

Hey all,

Looking for some feedback on my problem.
I have a 92 YJ 2.5L 4Cyl with the AX5 transmission and when in neutral and clutch released(up position) and at idle I hear and feel a rumble/grinding. When I push in on the clucth it goes away. But, when coasting in neutral with the clutch released this noise does not happen. What could this be? I am thinking it's the throw bearing, but wouldn't the noise still happen when I am coasting in neutral as well? Thanks all

Have you checked the oil level in your trans ?

No not yet. I will be doing a fluid change this weekend, but if that is not the case then what else could it be?

Could be bad bearings in the trans .

I agree, could be your input shaft bearing.

Only happens in neutral when at a dead stop and idle. Every other senario does not produce the sound. (eg. while in gear and moving, in neutral while moving or coasting). I guess the only thing to do is check the fluid levels. If that doesn't work then it defenetly needs to come off anyways. I just want to be prepared if I do have to take it off.

Actually it is due for a replacement or rebuild anyways. Almost 300,000kms on it and I do believe everything is original on the transmission. LOL!! This jeep has been very, very good to me with respect to my bank account even though I beat the crap out of it

I'm inclined to think throwout bearing. The fact that you can't hear it/feel it while coasting in neutral might be caused by just being distracted by the other things associated with a moving vehicle.

Definitely do an oil change on the gearbox and pay close attention to the fluid quality/condition of the old fluid, but my money still rides on the throwout bearing.

What oil are you planning on putting in the tranny?

There is no situation that cannot be improved with a small but well-placed explosive.

I am starting to feel lucky about it. Ever since I have been looking into this problem all I have been reading is how weak and crappy the AX5 is. Yes it may be weak, but the engine is pretty weak to boot. So they compliment each other pretty well There were issues with my AX5 ever since I purchased the jeep 5 or 6 years ago(eg. syncro problems and just being really noisy), but this is the first problem where I am actually concerned about the AX5 breaking down and having to do some work to it. If it is a bearing then it won't take long for that bearing to disintegrate I know that much. I will probably top up fluids and drive it until it needs replacing. It will be a good work out for my clutch leg at a red light.

Do a fluid change like Max said and pay attention to the old fluid, it should tell you a lot.

The noise this thing is making could not go unnoticed by other things happenning while moving while coasting. Believe me!! LOL! But I will definetly take it into concideration for sure.

I am thinking of putting Pennzoil Syncromesh in the tranny, but someone had told me just to use a 80/90 gear oil. What do you think?

Don't AX5 transmissions use ATF?

I don't think so!?!?! The Haynes book says 75/90 GL. But I am open to suggestions.
