new gears, whine on deceleration

[quick01snake]

My Ford Racing 4.10's do not whine at all... and a good, reputable, knowledgeable shop can do your install, but if they don't know Ford IRS gear installs very well, they will whine. You can't shim the carrier the same way you do solid 8.8's. The aluminum flexes more and and the carrier needs more preload on the sides to reduce this.

the carrier shifted just enough for once i put a load on it so i re shimed it and double checked pre load and wear pattern and put it in. the whine went almost fully away. just a slight whine on decal from 50 to 45 past that i cant hear anything. thanks guys
