I have a low growl/roar which sounds like a CV shaft going out.. but welli replaced the one which i suspected and to my surprise it still growls at me... it only growls when im turning at speeds above 25 mph... and only when turning right... and it sounds like it is coming from the left side... when the front in is not engaged it the growl is up and down.. but when the front end is engaged it is a pretty consistant growl with a slight up and down sound. if that makes sense... when i had the axle off i checked the front rear end.. i spun the diff flange around and it had a little rotation play back and forth... but none up and down left and right...when i was spining it i could hear the gears inside clicking. but im not sure if that is normal or not... that is all i really checked so any ideas are welcome thanks....

 

its was the wheel bearing. after a deep long thought process i leand agianst the tire and to my surprise the wheel was waddling... dur...

 

Glad to hear you solved your problem.
