Here are instructions on how to replace a wheel bearing assembly on an Infiniti G35.
The noise of a failing wheel bearing sounds like a brake caliper is sticking and leaving your brake on one wheel. I described it as a friction noise but I have heard it described as a whirling noise?
You will need a
14 mm socket
14 mm wrench
Say a prayer
Jack up the front of the car
Remove tire and brake rotor pads caliper and caliper mounting plate
Turn wheels left for drivers side right for passenger side.
remove 14mm bolt on lower mount for strut
Remove 4 17mm bolts from back of wheel bearing hub assembly. You will need to turn the wheel the opposite direction to get them all
Gently work the old hub/bearing assembly out of the spindle
There is a magnetic ABS sensor inside the hub/bearing assembly that feed through the spindle. Be careful to not break this part!
This is the old hub assembly you can see all the metallic dust coming out of the hub where the wheel bearing is failing
Old Vs New
Gently work the new hub/bearing assembly into the spindle being careful not to break the ABS sensor
Replace the four 17 mm bolts that hold the assembly on the spindle they are cheap and grade 9 fine thread these bolts should not be reused. I bought them from the dealership for about $4
Replace brake rotor, caliper mounting plate, caliper ect
put back on the tire take the car off the jack.
