1999 Chevy Tahoe howling noise?

[ch4d]

Hey guys im new here and I have not figured out what the issue is when ever i am slowing down form 25mph-0mph i am hearing a howling noise come from my driveshaft maybe... not sure But i just had the rear diff replaced because i blew it with a new motor I got. If i can get some info on this issue that would be great thanks guys

Maybe it is induction noise from that big motor

Who did the rear?? A howling rear end when getting off the throttle can be a coast side ring and pinion problem...

Take him for a ride and see if he thinks it's the rear end.
