so ive had this whining in the differential for awhile. it only seems to do it a part throttle, not during decel, or at accel just at part throttle. i had a problem awhile back where the ring gear bolts came out ( i ended up getting longer gear bolts and lock-tite'n the hell out of em). anyways went to take a look at the differential today and found that there was plenty of fluid, didnt seem like any wear marks but seemd like way too much play when i would turn the rear wheels back and forth. beings that i know just about nothing about rear ends im not sure what im supposed to be looking for. any help would be great!!
