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
jack
jack stand
