At 120K mi, had ALL the service work done. Changing the trans fluid as well as the 4WD differential was due. A noise in the rear diff began. So the mech said a Honda bulletin stated that this happens sometimes when changing the fluid. Ok. Changed it again. ANYWAY, the noise is still slightly there when going from a stopped position … steering wheel all the way to one side or the other … and giving the gas. IS THE REAR DIFF BEING DAMAGED?

Is it a limited-slip differential?? These require a special lubricant or additive…

Honda uses specific fluid for the rear diff. First step is make sure mechanic installed the appropriate fluid not some aftermarket stuff.
