Thank you for all the replies. I changed the gear oil in the front & rear differentials and transfer case with Amsoil Severe Gear 75W90 shortly after my original post back in 2014. The low frequency rumble persisted when making low speed tight turns like when backing out of a parking spot. I...

Thank you for the intel gents!

What do you guys think of these results? This is my first oil analysis so I am not sure what I am looking at. Is the aluminum content too high? I had 2 x FilterMag RA300 magnets on my oil filter too.

I need some help identifying the source of a rumble noise in my 2009 4runner. I am hearing a low frequency rumble noise in the cabin of my 4runner when making low speed turns, 2 -5 MPH. Example: When backing out of a parking spot and turn the steering wheel. Example 2: When making low speed...
