Are our wheel bearings and bushings sealed or are we able to grease them up ?
 

I'm having some squeaking noises when I turn my wheel ...idk if it's from the salt and sand from the NYC roads in the winter or what but it's annoying as he'll... If ours aren't sealed I'll ask the mechanic to grease them up for me

You can ask your mechanic to diagnose the noise for you, but none of the ball joints or bearings on our cars are servicable.

Okay thank you

Sealed bearing, been that way for over ten years.

Sealed....
....Sadly
Good news is bearings are cheap. Assuming its a serviceable bearing and well that's another story.
If you do replace bearings source them carefully good brand name doesn't mean everything anymore (i.e. timken has cheap bearings along with there high quality ones now)
