    Hey guys,
    Put in a used posi rear end, all seamed fine but I am getting a low humming sound on deceleration. Cant remember if that to much backlash or not enough.
    Appreciate any info you can throw my way.

    Not necessarily the backlash. It could possibly be the result of the pinion being too far away. Best thing to do it pull the cover. Check the current backlash and run a pattern with compound on both sides,drive and coast.

    Humming on decel could be a bad pinion bearing too

    Check the pinion see if you have any in out end play too. These are all simple no money ways to see where the trouble is.
