Hey All,

I'm getting a humming sound (non directional, but it sounds like it's coming
from the pass-rear), most pronounced around 40-60mph, loudest at
50mph...

Could it be the rear wheel bearings? (Brakes look okay, and it's definately
speed related.) (I did a search, and the only 5th gen rear wheel bearing
thread I could find...did not exist on the org.)

Doesn't seem to make a difference if I'm in a left or right sweeper, tone
of hum doesn't change.

Haven't changed anything recently (put responseedge rubber on it
about 5K miles ago, but that was 5K miles ago.) I am having a small
exhaust system problem, but it doesn't sound like the exhaust.

Car is a 2001SEAE, 104K miles, stock suspension.

Ideas?

 

Very common problem on 4th-5th gen Maximas.

You could very well need new wheel bearing/hub assemblies.

One way to find out for sure is to put a different set of tires on the rear, maybe from a friend's car, and see if there is a difference in the noise level. Yes, it's a lot of trouble but it will tend to isolate your problem better.

 

I know the front bearings were a problem (had mine replaced
years ago) but didn't remember reading that the rears were
as bad...

Oh well...

 

Just curious but is there any real way to tell which side is bad? To me it seems that my passenger side is bad, but my friend says driver side.

 

I'm going to have a friend drive the car up to speed, and ride in the back
seat with the pass through open.

I don't think I've ever ridden in my trunk...

 

Good idea lol i was gonna say just fold the rear seats down so you could hear better
