So I had my girlfriend put the car in reverse and drive while I peered underneath. I realized the sound was coming from further back. So I jacked it up and found it's that damn rear CV joint on prop shaft again. I have replaced it twice. I feel like I must be installing it incorrectly. Going to take it off and see what the bearings look like. I really struggled with the install. I just dread doing it again. So not TC chain. Does anyone else find connecting the drive shaft at rear differential difficult?
