No cant be, I had one of my guys trying to find the source while i loaded the drivetrain with the brakes applied. Only made noise in R, D, 2,1... Not in park or neutral...I assume because it had no load on whatever was making the sound.
Ya, U joint will make noise when a load is on it not so much without a load.
step on the brake so the jeep wont move shift from rev to D do you get the noise?
in drive with foot on brake but allow jeep to move do you get the noise?
is the noise frequency the same as motor or 3 times as fast as wheels?
I dont buy piston slap or bearing slap ONLY when changing gears. not going to happen
If it sat all summer could be a seized U joint IF it happens ONLY when the jeep moves.
Bad U joint when moving or shifting D to Rev

Wow, that'd be a pretty cool U-joint that can tell when fluid was topped off...or did you guys miss this part?

It's not a u joint, I know what a bad one sounds like, plus you have to be moving to hear a u joint when its bad. When we did the brake stand, the noise would raise and lower with the speed of the engine ONLY when in gear. I'm thinking it could have been the torque converter wasn't full or something. Last winter we did have one of the trans lines rust out and piss fluid all out. The lines were replaced and ran perfectly for months until the last storm of the season when the noise started. Hopefully it's gone for good, but I'm still stumped.
