hey guys, i have the NV3550 and NP231, since a couple of mud runs i have a whine in the drive train, seems to happen in 3rd, 4th and 5th gears, and seems to start after 1500RPM, i have changed my tranny fluid and the T/C fliud thinking they may have been contaminated and that it may help, however it's still there, any suggestions? could it be clutch related?

my noise seems to be coming from the tranny / T/C area, it's totally gone when i'm off the throttle or in neutral, it's only under torque.... and the clutch still seems to engage and disengage fine.... could it be the pilot bearing or throwou bearing, i'm thinking it's clutch related or something in that area....whats involved in changing the pilot bearing, the only part of the heep that i'm yeat to tear into is the tranny...

Thanks

anyone?

Think about how the clutch works. Once in gear and under way in a torque stituation the clutch should not be doing anything but spinning with the flywheel. Probly not clutch. I vote a bad output or other bearing in the trans and could have been caused by bad alignment of the adapter or something like that. Not much to go on in your post what else can you give us.

Thanks

well just got back from my drive, it's sure is prominant in 4th gear at 70km/h, it's only there under load, and the sound is totally gone when i'm off the throttle but still in gear, it starts again at any hint of throttle input.

at a stand still there is no sound at all regardless of the clutch being in ot out, and again, it seems to be coming from the mid of the jeep, not the rear axle, thats why i'm thinking tranny or t/c.
