I have a front end “growl” at 50mp+ all u joints on front and rear shaft replaced, centering yoke on front shaft replaced, and literally every wearable part up front is brand new. The noise was there before I did all of this so it’s nothing I did.
It’s not there if I remove front driveshaft which leads me to believe front diff or t case? A few months ago I had to front diff cover off and replaced fluid but honestly did not inspect for any damage because 1 I was kind of in a hurry and 2 I was certain the noise was because of u joints which I hadn’t replaced at that time
Any ideas?
