I am needing to replace the front hub wheel bearing assemblies on my 03 F250 4x4. I know Ford changed the studs from coarse thread to fine thread in between the 02 and 03 model years. Mine has a build date of 08/02 and I haven't been able to find the exact date they switched over. I'm ordering the parts on line and want to get it right the first time. Any help is greatly appreciated.

 

Can you remove a stud and gauge the threads?

 

I took a lug nut off and went in to autozone to thread one one to make sure then ordered it up.

 

Thanks for the help. I'll just take a lug nut to the local auto parts store and try it.
