the hubs on my pickup don't look like they lock manually. when I pulled the wheels off today I broke one of the black plastic center covers. where can I buy replacements? and what do you guys think... should I look into getting free wheeling hubs for the front or just keep it like it was and get the OEM black plastic covers?

 

I am not sure just what plastic piece you broke.

If you have the ADD system my drive flanges are steel

With the Aluminum wheels there is a plastic center cap is this what you broke??

Manual hubs if you want to get them go for it .

You can either leave the add system intact or lock it in the engaged position
