No, I don't get the ratcheting noise on the street (but we do in our race car on the road course rounding corners) we plan to change it for a non locker, it's not a good road course rear. What I get is a weird harmonic reverberation noise, sort of a "rumm rumm rumm" sound (maybe it's drunk LOL!), all else has been checked, drive shaft and u-joints are new and right, etc. it's definitely the rear and all looks healthy inside (it's a nearly new unit).
