I am trying to find the correct front wheel assembly for my 2001 2wd Ram. I have gone to Napa, Autozone and Advance. The one they are telling me I should have on the truck is not what is on the truck. The one they all say I should have has a large gear on the back side of the assembly. The one that is on the truck now does not have that gear. I am not even sure what that gear is for. Can anyone tell me what is going on with this? I took the wheel assembly up to Autozone and they just gave up. Heeeelllllllppppp
This is what come off the truck wheel assembly 1.jpg
And this is what them say should be on the truckwheel assembly 2.jpg
What is the gear on the outside of the second wheel assembly for? and will it fit my truck?
