Chirping from the rear end somewhere?

I had a rumble in my rear end for a while that occurred as soon as i would let go of the gas pedal. I put grease in the zerk fitting on the DS as well as the lower u-joint closest to the rear axle. now as soon as i touch the gas pedal there is a chirpping sound. i checked all the ujoints on the DS and there doesnt seem to be any play in the DS at all. but as soon as i let go of the gas the chirp goes away

what could be causing the chirp from the rear?

Do you have factory limited slip axel? Do you have friction modifier in the axel?

It sounds like the ujoints. Look closely around the caps for rust. Better yet, unbolt the driveshaft from the yoke and exercise it around feeling for tight spots.

The pinion climbs under torque, changing the ujoint angle and causing the squeak.

93gc, no i dont have the factory LSD. and no friction modifier in it either.

Is your jeep lifted? I started to get that noise from the slip yoke on the rear driveshaft after lifting my jeep. When you let off the gas the pinion drops down, which pulls the shaft out of the transfer case a little bit, which allows for a little more slop in the yoke.
