road noise 2003 VUE

I have a 2003 VUE 4 cylinder with CVT transmission
I bought it as a demo unit with 7000Km on it
I now have 16000KM on it and have started noticing
that the amount of road noise seems to be getting louder.
It sounds like the steady drone of airplane engines when
I'm at highway speeds 90 kph. but its also noticable
at lower speeds down to about 40 kph. I checked the
tire pressure and its at 32psi on all 4 tires. I have read
that 2002-2003 models were noisier than the 2004 models. It drives very well
and has no hestitation and
accelerates well, but I'm a bit concerned because I heard
a lot of stories about the CVT trannies blowing up.
Any info is greatly appreciated.

Some customers may comment on a drone noise between 50 to 75
mph (80 - 120 km/h). This noise may be accompanied with a

Vibration Analyzer, J38792A, or similar tool, look for a
30Hz vibration that exceeds 0.1 g's at 70 mph (113km/h).

Important :The notches in the bushing assembly must be
oriented at the 12 and 6 o'clock positions.

procedures. (Refer to "Differential Carrier Assembly Mount
Replacement" procedure in the appropriate Saturn VUE Service
