This is for a '99 Maxima I bought this fall, and I just put new tires on it. The guy changing the tires pointed out that the "inner hub" is missing on two wheels.

It's the 2-2.5" diameter "cap" that keeps grease in the wheel bearing area and keeps the dust/dirt out of the bearing. It fits over the threaded rod, cotter pin, and nut sticking out of the center of the brake assembly. Could anyone help out with a technical name for this cap so I can find it online (or a recommendation on where to find it)? Are there any other parts I'll need in conjunction with the cap? Also, how urgent is it to get this replaced?

Thanks, I appreciate your help.

Dust cap

Just go to the dealer, can't be too much $$$.

 

You were right, they're just $8 each at the dealer. I also found out that they only go on the rear axle, so I don't actually need them.

 

Yep, only on the rear.

P.S. If you get rims for your car, you'll probably need to remove the dustcaps to fit the rear wheels on.
