Toyota Repair: 98 Tacoma Noise From Driveshaft u-joints feel tight, driveshaft, driving me crazy

Question
I hear a noise thats driving me crazy PLEASE HELP My truck is lifted but haven't had the noise until of late. Only after speed of 25 mph (most of time) let off of gas (it stops) or if you push in clutch (it stops) jacked it up on jackstands listened closely sounds towards middle of driveshaft, but sounds like coming from driveshaft it does have a little play in the (carriage bearing?) its a metal scatching screeching sounds Really really annoying Plese Help Thanks Jason  

Answer
The problem is that one or more of the U-joints has failed and needs to be replaced, I would remove the driveshaft and check all the U-joints and the center bearing, if any of the U-joints have excessive play or don't rotate smoothly or hang up while trying to move them by hand they are the problem.
