bad gear sound

I just got done putting gears and lockers in my Jeep, the tooth pattern looks good everything looks good. When I took it on a test drive I didn't even get it out of the driveway when I noticed that there was a grinding sound when I let off of the gas to shift or slow down. When accelerating it all sounds good. This is my first gear change so any thoughts on this problem would be helpful. I thought that it was coming from the front but when I took the cover off I did not see nothing that looked out of the ordinary.

When driving my jeep my after the gear swap, I too got a pretty strange sound. Basically it was high pitched and when I would lightly sit on the skinny pedal grinding would be added to the high pitched sound. I took it back to the guy and he said I had "burned the face off the gear". So I bought another gear set and install kit and he again installed the gears. I followed the recommended break in to the tee but again I got the same sound. I was told that the guy did not use a case spreader and follow proper spec on the Dana casing. I am not sure exactly what that means but my sound is only above 55-60. So I figure I will drive it till I blow the rear end up and either do a 8.8 or a 44. Just my $.02. Hope it helps a little
