Weird noise from front end

It's not cheap for the size, but it's the only one you want to use.

Here is a link to the 350z fix. The 370 is basically the same, with the difference being the axle nut torque being different depending on which version of axle nut you have.

I will also say my brand new OEM hubs click under heavier loading, but I have never had any issues out of them from it. The old ones did it for awhile, then stopped. The new ones did it as well, now it's starting to fade away.

I have noticed it at higher speeds going over railroad tracked .. but the most is when turning and accelerating ... it's not so much the motion from forward or backward it seems to the up and down of the front end that I can replicate it
