My 02 F350 drivers side has a slight growl to it. Is this normally a bearing or lockout? How can u tell the difference between the two? If it is the lockout which brand is a good replacement fo stock. I have used Mile Marker in the past but don't know if they make them for the F350's.
Thanks for the help!

does it growl when the hubs are locked in

 

Mile marker makes em. I believe it's the 449ss but double check. I say they are just as good as warn but less $.

 

Yup, that's the number. Put on a set last year and have been loving them ever since.

 

I have not locked them since the noise started. They do turn free though. I will have to lock them and see if the noise goes a way.
