Whistling noise from my 2005 chevy equinox

If it only clunks on a left or right turn. Then check the upper strut mount, these are known to make noise. Or it may need an upper strut plate. God-Bless!

There are two rear Wheel hub on a chevy equinox. You also have a rear differential containing bearings.

There is no "cheking"to be done other than what you have done already.The movement,ANY movement,only means the universal joint is shot and needs replaced.I'm sure you've noticed a steady vibration.It's coming from bad U-joint.Replace it.

Cv shaft is bad, ( drive shaft from Trans to wheel. )

Take it to a qualified repair shop .

depends on the noise , I know that sounds silly, but it works,, is the noise your hearing a clicking sound as you turn? if so, its the CV axles going out ,, From your info I don't know if you have the all wheel drive or just the front wheel drive, but if you hear clicking, its CV joints going bad, Now if what your hearing is a squealing noise, that would be the power steering pump, look at where your fan belt is and what all it drives,, one of those will be your power steering pump, some models have the fill tube for them right on the unit itself, and others have a off pump location for filling, however your year happens to be the a first generation and they used electronic power steering, and naturally you need to have it dealer checked

Its a wheel bearing making that roaring sound now you just have to pin point which wheel its coming from.Have somebody ride in the back seat and set on one side then the other you'll here which side is the loudest then replace that side.These cars are famous for more than one wheel bearing going out so don't be suprise if have to replace more than one.

My 2 have always made that noise, I'm guessing it has something to do with the ABS charging in preparation for potential use. after a combined total of 240k miles, there has been no noted detrimental effect to this "charging" sound.
Great car.

check the wheel wells for a loose liner that will rub when making turns and will come and go as it shifts sometimes also

Here is the problem: It is the speed sensor for your wheel. Apparently mine was all jacked up and possibly could have happened during driving. The wires on mine apparently are all screwed up from whatever trauma it suffered. I'm on my way to go it now...........$240 OUCH!
