Really scratching my head here. Bout to leave bald spots from it.

I had a shop assist me with a differential fluid change, U-Joint replace to the front of the transmission and to the differential. My fault probably being impatient. Right after it, this sound began to occur and I honestly do not feel like going back to them until I get a little more evidence this is a differential issue.


As for the transmission, no work was done to it other than the Ujoint that connects to the driveshaft...

Differential or transmission?
