I took my g35x into the infiniti dealership yesterday becuase I was getting some vibration and loud humming noise coming from the front of the car while doing 50+ mph. They told me that its going to need a new front bearing ($650 w/labor) and it may need a new hub ($350 w/labor). It almost seemed like he was trying to get to a thousand. My questions: Is this a standard price for this kind of repair? also... how hard would it be to do this repair myself? Are there any DIY videos?

 

Try a good Indy shop.

For the front in a regular RWD you can get the oem parts pressed together and ready to bolt in, slightly harder than a brake job. I don't know about the x

 

Is there such thing as a "wheel hub assembly" for the front 05 g35x that comes with bearings and hubs together in one piece/pressed. I found TIMKEN has a wheel hub assembly at parts geek.

I'm a bit skeptical because as far as I know its suppose to be 2 separate pieces.( hub and bearing). Can anyone confirm this?

 

You can get them separate but the install is much easier if you get the whole assembly.
