Drive line slop

[Jansen]

I have driveline slop that normal occurs from 2nd-3rd and somtimes 3rd-4th and when I turn a corner I can hear the G80 talking. It isn't that loud I guess a small click and the radio has to be kind of low for it to be heard. Is this normal and will changing the rear diff fluid make any difference? I have a little over 4000 miles. For the G80 rear end how much friction modifier does it take?

 

Thanks
