So I'm about to call randy's ring & pinion on monday to see what they say... maybe use the good ol warranty

I'm getting a high pitch whine coming from the drive train at anything above ~10mph. Its all the same loudness and frequency/pitch of sound, regardless of RPM's or speed, and all started right after getting my rear ARB installed and a new bearing kit, and then only AFTER engaging the locker for the first time. Now it does it regardless of being locked or not. I'm just wondering which of those might be the culprit, or what else?

 

any thoughts?

RR&P is suggesting 'normal gear noise', improper backlash, or perhaps an axle bearing gone bad after engaging the locker? Do these sound reasonable/feasible? I have little knowledge of R&P's gone wrong...

 

put it on set of jack stand and have some on put it in drive while you get up under the truck, so you can hear the rear end and the driveshaft...

fyi don bust through you garage...
