Okay finally over this last weekend i got my car running again. I just swaped the rear end over to a moser Ford 9" rear and all spohn rear suspension, ebiach drag launch springs lakewood shocks and wilwood pro-street brakes. I brought the car to my mechanic to install the brakes (dont wanna mess up there) and when the tow truck was backing it into the driveway i hear this weird nosie like a metal/rubber to metal sound clicking, so i think wow i guess these rear ends are loud. So i finish the misc stuff i had to do charged the battery and finally got her started again. Still wery over the new rearend and my thoughts and of other friends I wanted to warm up the rear end before moving the car. With the rear end supported on jackstands i shifted the car into drive and let my foot off the brakes. Then i hear the sound again, this time getting progressly louder as the tires spin faster. praying to *** that that was not my new rearend i put on the brakes and had one of my friends do the same thing(let car idle) as i try to locate the sound. to my relief the sound was not coming from the rearend but by the yoke on the transmission, or around there. Oh and a little backround. rear end locked up going 35 under no throttle in the spring. I replaced the rear end, and was hoping to get a probuilt trans but money is tight right now so i have to wait till the spring. The transmission leaked about 1 quart of fluid while at the garage, because the drive shaft wasnt in.
Im guessing (well hoping) that it might be the front ujoint because the sound clicks about as fast as the driveshaft turns. again it is a metallic/rubber to metallic sound.

Wellll, put it back up on jackstands and remove the driveshaft. Start engine and put in gear. Same noise?

Move driveshaft U-joints back & forth. Stiff? Noise? Binding? Try another driveshaft.

Check driveshaft for rub marks. May have been rubbing on brake cables, exhaust hanger. . .

If noise is gone w/o driveshaft then check brake pads, calipers and such for rubbing. Turn driveshaft by hand and see/feel for noise.

With the rear locking at speed there was a lot of torque on the driveline parts.

Most likely some fluid will come out. If the rear is up in the air it shouldn't be too much. As it is you shouldn't need to run it for long like that to discern if the noise if present. If you have a spare yoke around place it into the trans. Just don't rev it up a lot or continuously as it may walk out.

Another thing came to mind are the U-joint angles. With a new rear they may be off.
