If there is excessive play (backlash) between the R&P gears, it will be making noise (howling) & the gears will be trashed.
Usually the play is in the differential unit. It is a result of wear to the axle gears/thrust washers, spyder gears/thrust washers, shaft, and sometimes worn thrust faces in the carrier, that result in "lost motion" in the power transmission between the carrier and the drive axles.
The stub axle splines wear as well.
If the R&P gears are OK, it's not too bad of a job but if it needs a major rebuild it can be a real PITA to set up correctly.
You won't know the condition until you remove it & do a detailed inspection.
