strange humming noise coming from rear

[am6948]

I have an 04 with 34000 miles, humming noise from the RR area, needed new wheel bearing assembly.

As noted earlier about a month ago the dealership replaced the torque converter in my '05 N*. Since then no problem and no noise.

Have 05 AWD SRX (4000 miles), Makes rear end whine like bad ring & pinion at 25 to 30 mph at light throttle and even more whine at 40 MPH under compression! Cadillac has replaced rear end, both rear wheel bearings. Still has same rear end whines. They are to look at car again next week. My info is this is common in AWD SRX's

I have 07 srx,2wd. same humming intermittent noise, goes away when accelerating,otherwise it's always there, seems like a tire out of round, but there's no bumping which leads me to believe some thing to do w/ drive train. Dealer says every thing is fine. It' driving me nuts. Help!!

'06, N*, AWD. Just came back from dealer after my second visit regarding an annoying hum coming from the rear end usually occuring at about 1500 rpm. Initally dealer claimed issue with exhaust note. However after the last visit they concluded the torque converter required replacement. Replaced. Happy at last ....

Don't let them tell you it is some other issue. GM has issued a bulletin to replace the converter. Don't take anything less.

How much does that run? Mine was making the humming noise now I get a slight squealing from the RR tire. I think it's a bearing also, but I'm out of the warranty.

Cadjack- Do you know what bulletin it is that was issued for the torque convetor?
I have an 04 SRX that makes a humming noise anytime I'm on the highway,I cant hear the noise when the radio is on but If it's off I can tell its there.

Anyone know what the Service Bulleting # is on the Torque Converter? I may have the same issue and it is driving me nuts...

Also, anyone know if the service bulletins are covered by GM? I am out of warranty on my 04 V8 and assume this is a pricey fix.

Thanks
