Rear Wheel Bearing Hub assembly Replacement
STOP: Please read the entire DIY before proceeding.
PROBLEM: My wheel was extremely wobbly to the point where when the car moved, the rear caliper was rubbing metal on metal with the rotor. I diagnosed it as a axle nut that had come very loose, so I re-tightened. Everything was fine until a week ago when I discovered that the nut had become loose again.
Upon re-tightening and driving, I could hear a distinct rubbing sound at slow speeds. I checked my entire suspension and did not notice anything unusual. When I had the rear of the car jacked-up, I placed one hand on top of the tire and the other hand on the bottom of the tire and moved it in and out and felt play along the vertical and horizontal axis. The passenger side did not exhibit this movement.
I researched and discovered it could be the result of a wheel bearing that had failed. I have taken my 2003 G35 Coupe to three track events and a couple of drag events and the car currently has 45, XXX miles.
Drivetrain warranty is 6 yrs / 70, 000 miles, I had no choice to do it myself or pay a dealership close to $500 in labor. A reputable shop in the LA quoted me a bit under $300.
