Having problems with your 2000 Chevrolet Blazer ?

I have a2000 chevy blazer 4 wheel drive 2 door ....terrible constant growling noise. Cant figure out from where but it doesnt stop or really even change when turning left or right. Thought it was a hub and bearing...the bad tires...but now im thinking rear differential. Does the rear dif make a constant noise or only when turning the wheel? What could this be?

Answers :

Driveline and wheel bearing noises can be very decieving. - especially on 4X4 vehicles. These noises can travel through the vehicle and sound like they are coming from one place when they are caused by something else. I have 2 recomendations:
\012
\0121. Take it to a professional that deals with 4X4 drive trains and have him lend you an ear.
\012
\0122. get the thing on a lift and listen to the components with a stethescope. It could be a wheel bearing, a differential, a transfer case, or even the transmission making a noise like you have described.
I would be looking at u-joints and CV (constant velocity) joints before diff. All will make noise when rolling regardless if turning or not. If you can get it up on hoist/lift, have someone "man" the cab and let it idle in gear, then you'll find your mystery growl.
