NOISEY 8 3/4 .Any advice

So after putting in a 323 sg a body rear in the duster last w/e i finally got a chance to drive it...NOISEY is the word..id call the noise typical stick shift noise..not a bearing whine, like an idler bearing but a definate constant whine whether you are on the gas or coasting...the noise goes away if i push the clutch in..Before installing last week.i put a different pinion yoke in it along with a new seal..torqued to factory specs..I browsed fabo forum and found some information on other threads that have questions and and problems exactly like im experiencing..The axles are new dr diff with new green wheel bearings..can i have done the same thing..Torqued and changed the running geometry on that rear ..i have no idea on any of the specs/clearances before i put it under the car..but it sure is noisey..the 8 1/4 i took out was far quieter..HELP..TX..J
