Those ones that Napa carry are sold by Precision but low quality made in China garbage... I was going to run Precision Super Strength... That's what I have in the 44 before I ripped all the ears off the drive side axle... And also because I can warranty them non-stop through my store without any problems...
I'm open to suggestions and appreciate all the info... Last thing I want is to be beating down on the truck and next thing I know I have a U-joint fail out in the middle of nowhere...
