Rearend or Tranny?

I just acquired a 93 wrangler and it has an issue with a loud clanking sound when driving forward. When you disengage the clutch and are moving forward the clunking begins and sounds like it runs in conjunction with the driveshaft spinning. I have replace the u-joints. I also removed the rear driveshaft and put in 4 high and 4 low and the clanking was not there. I have lifted the rear end and put on stands and with the transmision in any gear you can move the rear tires about a 1/4 of a turn and there is a clicking sound when they engage. I was told that it had a locker in the rear end, but no reciepts or anything on that. Does anyone have any idea or ran into this in the past????? It does not do it in reverse. Thanks!!!!!

Where does it sound like its coming from? The front the middle or the rear of the jeep? Then does it favor one side or the other?

Get a buddy to help you, and drive the jeep slowly forward and back ward, have one of you out look at the rear driveshaft as it spins. Pay attention to the area arond the diff/yoke area. You will be looking to see if it rotates smoothly or if it skips as it spins. If if skips, then issue with ring gear or locker or what ever is in there. At that point pop the diff cover and see what you have going on. btw a locker if working correctly should not make clanking sounds under normal condidtions.. you might get some clicking in corner turns or hard turns from a stop.

It sounds like the center, but could be rear, does not make a difference when you turn either way. When you let off the gas it does not go away, but almost does. When you push in on the clutch it goes away completly.
