front end humming 2006 pontiac torrent

Asked by Aug 31, 2016 at 06:30 PM about the 2006 Pontiac Torrent AWD

Question type: Maintenance & Repair

I bought a 2006 pontiac torrent last November.  It
has been a nightmare. There is a front end
humming that sounds centre of the vehicle. It's
loudest at around 70kmh  but mostly gets louder
the faster you go. I've had the wheel hub
assemblies replaced, new centre bearing, new rear
drive shaft, new tires, new rear diff, and new
transfer case.  And after all those bad series of
events the humming is STILL there. I around
around my around my total loss as to why I can't
get this howl to go away. My mechanic has
basically given up on it. I've looked it up on many
forums and everyone always says wheel hub/new
tires. Neither of these solutions worked for me.
Any other ideas?

Did the mechanic check the CV joints/front axles?

Did you ever find out what it was. Im having the same issue

I ended up doing all 4 wheel bearings and the half shafts in the front and it went away. I suspect it is the wheel bearing as I've gone through quite a few with this vehicle. I bought higher quality bearings and they've been good since and the noise went away almost a year now with no hum. But otherwise this vehicle is still a money pit. It's awful.
