Re: Front Wheel Bearing Noise???
Dealer is the only option. Go to IOS to get the best price. Call them if needed & speak to Joe in parts.
It's also not entirely DIY. IA part of the process requires a press to assemble it. If I remember right, I was charged about $40 to press in both.

Just bought both fronts for a little over 100 bucks from the amazon link shipped. Thanks freddie for that info.
Re: Front Wheel Bearing Noise???
My 2006 M35x L/F wheel bearing started making noise at about 85k miles or so. I replaced both sides while I was at it.
I bought a set of genuine Infiniti OEM bearings, and I know you can buy knockoffs cheaper. I just would not take a chance with wheel bearings, mainly because it is a PITA to have to do it over again due to premature failure.
Even though only my L/F was noisey, my right front was nowhere as smooth as the new bearing upon inspection after removal!
Some fast R&R notes as I recall:
Upon dis-assembly, you must remove the brake sensor from the hub prior to pulling the old hub off.
If you do not remove the sensor, you will break it!
Note the orientation of the sensor hole within the hub.
Upon re-installation the hub, you must be sure the hole is correctly aligned before bolting down the hub so that you can re-install the sensor!
You will need a socket large & deep enough to fit the axle shaft nut, remove the center cap, you will see it. (I forget the size)
My axle shaft splines were frozen into the old hubs. If yours are frozen, be careful not to damage the threaded shaft ends when trying to free them up!
This is the kind of job that since you are going to be removing your calipers & rotors, now is the time to see if they need work also!
You Tube has a few videos on hub R&R as I recall. Torque specs I found on internet also. I wanted to replace the axle nuts, but did not find anyone who had them in stock!
Good Luck,

Re: Front Wheel Bearing Noise???
What does wheel bearing noise sound like? Clicking? Squealing? Metal on metal? High pitch? Low drone? And as far as rocking the wheel, will the wheel always rock if the bearing is bad?
Re: Front Wheel Bearing Noise???
Good question TDot!
As you can see, wheel bearing noise is largely mis-diagnosed as tire noise. Many threads are written about shops telling owners "it's tires!" resulting in $$$tires, and no change in noise! Pretty shameful on the part of these lazy incompetent shops!
As far as tires vs bearings, I sometimes swap tires to determine if they are the culprit, if I have any doubt! A bad tire will drone like a bearing, but will usually not change pitch under various loads (turns) as a bearing will. A bad tire, moved front to rear, can usually help in diagnosis since you will feel the noise "move" slightly from where you originally heard it emanate from.
A lightly worn bearing will mostly show itself as a medium frequency drone usually at speeds 20+mph & above. This drone may may become more pronounced or reduced in a turn, especially notable on highway on / off ramps. As the bearing wear progressives, the drone usually becomes more pronounced.
Rocking a wheel and turning a tire by hand are not effective in diagnosing. Usually a worn bearing will not "click"; however, a worn drive-shaft joint will!
A severely worn/damaged bearing will produce a grinding noise. That's easy! At this stage, it is also easy to determine what side is bad.
For the most part, it is only after to old hub is in your hand that you can tell if it is worn. (turn it by hand back & forth).
About our cars; specically M35x's;
I find from this & other forums that front wheel bearing failures typically can occur as early as 70k to 87k miles. I had mine fail at 85k miles!
I made an error in my previous post, I confused L/F & R/F. It was my R/F that failed, which is typical, as the R/F is curbside & usually takes more abuse.
