Raise your car and see the difference. As annoying as it is, you'll be surprised. I just did that last weekend

 

I actually was thinking of doing this. Will do it this week.

 

I haven't been on here in awhile, but I thought I'd give an update. Since the axle install, the vibration has not stopped, although it is intermittent. I've gone weeks without the vibration and then it comes back. I've put over 10,000 miles on them too.

I also did a wheel balance, which dramatically helped at highway speeds.

A new issue has shown up, which is squeaking from the strut tower. I've already diagnosed it as a bad strut mount & strut bearing, which I plan on replacing. Could it be the culprit? Not sure, but it is on the drivers side where the vibration occurs. I'll post the results when I get around to it. Good luck to the rest of you!
