HELLO , I hope everyone is having a great day ! I need help finding the names of the 4x4 parts that are in the wheel hub please . I recently purchased this truck and it started making a strange noise while driving it. after a visual inspection finding nothing out of place I decided to search a little deeper , I also wanted to replace the Break Pads and Rotors when i pulled the center cap off the wheel a bunch off the 4 wheel drive parts Came/Fell off with the center cap . this truck has automatic hubs (You can engage the 4x4 either High or Low from inside the truck) i need to find out what the names of these parts are so i can replace them asap. Thanks for your help.
