Wheel center difference

I decided to paint the chrome badge red using plastic dip. Because I think chrome sucks. Took the front centers off and was like cool maybe I can just leave it like this it looks great without them. Then took the rears off and...I guess not. Apologies if this is a stupid and obvious question but why are they different?

 

One of those is housing the pawls that engage front wheel drive. The other one is a drum.

 

The front and rear axles are built differently.

The rear wheel always points the same direction so there is a solid shaft attached to a flange for the wheel to bolt on to similar to this:



The front wheel needs to be able to turn to steer so it has a flexible axle using a constant velocity joint similar to this:



Notice the big nut on the right? That is what is under the nice looking cap on your front wheel.

 

Thank you. This forum is the best. I've been on plenty of auto forums and I'm always amazed by the knowledge on this one. As well as the excellent humor.

 

Everyone starts at the beginning, it is amazing how much you can learn just by reading & asking questions. This forum is a excellent resource -- and good for a laugh too.

 

Rusty, I fixed your post for ya! Have a great day my friend.
