I get this signal click coming from the rear end once i take off. i thought it was the drive shaft (u-joints). i replaced with a low mile unit.
It got better but it is now intermittently still there.

I was able to make it happen as i drove off of a small bump coming out of a drive way

Any help would be greatly appreciated.
Thank you

Going to change diff fluid and drive shaft blots with blue lock tight this weekend to see if that helps
