My father in law has an 07 f150 4x4 with 5.4. Recently he noticed it making a dull grinding noise when turning. There is no clicking or popping, just a dull grinding that is very noticeable. Only makes the sounds when turning though. Would this be a cv joint going bad or a wheel bearing. what are some good ways to determine what it could be? thanks again for all the help

 

Sounds like it could be a hub. Has he grabbed the CV axle and checked it for excessive play?

 

i am going to look at it today. So, I just grab the cv axle and shake it to see if there is excess play? do I do that with the front end off the ground or on the ground. thanks!!

 

When you do it also look real close between the flaps of the cv. Some people mistake a bad cv axle for a wheel bearing because they don't see the tears unless they take the cv axle off and fully extend it.

 

On ground- thinking of the obvious things, checking for a broken axle joint. I had a broken one a while back and it wasn't exactly letting itself be known. I wiggled that thing and sure enough...
