you could possibily have a high spot on your pinion gear


that is a part in the differential right?

Robert Miller

Yes it is


well I just had that entire unit replaced with a new one also I had my transfer case replaced the entire unit. the noise is still their


also the sound is coming from the front driver side wheel if that helps at all

Robert Miller

Then you prolly have a bad hub


ok guys thanks but I also had all of my wheel bearings replaced brand new. this is why im having this huge dilemma. I have been going to several auto shops including ford dealer, and all the things you guys are telling me I had done already because they said the same things


and yet I still have the same loud noise coming from the front end driver side


how about making sure that the transfer case has enough gear oil in it
