So it happens when I shift and when I let of the gas and lightly tap it again. I know it's comming for the rear differential. I also noticed when I first get in the car before even starting it and I press the clutch when the car moves a bit I hear it again. I changed my ds to 1 piece thinking that would be it but it didn't help. Someone said diff carrier bushings. If that's the case how hard is it to replace them? Or what elese could it be? Btw I'm pretty sure the diff crarrier moves a bit when I push up on the ds right where it meets the diff.
