Rear left wheel bearing is squeaking - 2002 Chevrolet TrailBlazer

Sounds like wheel bearing going out.




Performance Air Intakes

What makes you sure its the bearing? Sound like your brake to me? Is the brake disc or brake drum a rusty red colour?

check wheel bearing... and make sure that the metal shims are installed with the pads. they prevent noises

Beyond the issues of dry wheel bearings and CV joints, various points in the suspension (front and rear) have rubber pivot points that get squeaky when moved. Try pushing down on each corner of the car to try to locate the area of the noise. Is it worse on rough roads or smooth? Make sure that all of the lug nuts on the wheels are tight. Lastly, doors, hood, and trunk lid can squeak if they move while driving. Silicon spray lubricant works on all rubber surfaces. Wheel bearing grease works on wheel bearings and CV joints--look for wear and replace any damaged part.

More likely this is a wheel bearing or CV joint than suspension components.

One good indication is if, when your making a right turn or accelerating, there is a shudder or shaking in the steering wheel then its likely a wheel bearing.

Another good indicator can be found when you jack up the suspicious wheel. Put one hand on the top of the wheel and one on the bottom and pull back and forth. If the wheel makes a clunking noise and moves in either direction, then wheel bearing is shot.

Rear wheel bearings don't squeak, what could have happened is the brake shoe retaining clip hardware may have broke. Common to break due to corrosion if they have never been replaced. I always buy the brake shoe spring retaining kit every second break job since there only $15.00 at Auto Zone. 
The other thing to that the squeak could be coming from is the U joints at the drive shaft. The U joints may have gone dry of grease and needs to be replaced, You have two of them and the drive shaft needs to be removed to change the U joints so might as well have both of them changed. 
Good luck and hope this helps.

sounds like the front brakes need replacing, that what the squeal is. They are made to do that so you know when to replace them

Lots of things to check. Rear wheels, lug nuts, loose suspension piece, rear wheel bearing, since this is a rear wheel drive car i would also check the u-joints. From your description, it sounds either like a loose wheel or a wheel bearing, since the noise and vibration only occurs when you are turning. Hope this helps you, Rick

this would not be a wheel bearing, it sounds like a driveshaft universal joint noise.

Common causes for High-pitched noise from rear wheels are:

The wheel bearing: this is not usually dangerous in the short term, but I recommend contacting a mechanic and having it fixed. To test the wheel bearing, you lock front wheels, and jack up the car rear and spin the wheel (handbrake unlocked). If bearing is worn you hear a drone. When is the bearing, often car starts vibration above 40 mph.
Noise from bearing can be continuous, intermittent, only when steering, only when hot.

The brake pads: when brake pads are worn out they start making a squealing noise, in this case the noise is only when you brake or continuous. When you jack up the car the wheel may be a little stiff, but not necessarily.When brake pads are completely gone you also hear a scratching noise when braking. Inspect your brakes immediately.

Other suspension problems: Jack up the car as suggested above, check if the wheel has a slight play on the sides. Check all of the suspension components, suspension mounting points, and steering linkage for damage. Also, check the frame rail for wrinkles. It is very important that these components be in good condition, if you notice any problem here, go immediately to a mechanic.

Try doing the simple test above, reinstalling the wheel and working the tire back and forth. This is a common test for bad ball joints and wheel bearings.
