Question about Chevrolet Colorado

1 Answer

Hi, I have a 3.0td Chevrolet Colorado, recently had new front discs and pads. The ABS light is now on permanently and there is a humming type noise whilst idling, when I touch the accelerator or whilst driving the humming noise goes. It only does the noise when im driving when I completely takine my foot off the accelerator and coast. Any ideas I seem to use alot of fuel and it doesnt seems as if something is holding it back whilst accelerating.

Could be two different problems. You would need to get the computer scanned for trouble codes to proceed with the abs light.

SOURCE: Alero loud humming/roaring sound coming from front end.

That's indicative of a wheel bearing, which is why you were told to change that out. However, it's also possible that the carrier bearings in the differential (where the drive axles attach) have gone bad. That happened to me on my 300ZX several years ago, and I had to replace the diff bearings. I would have them checked out somewhere other than a dealer (you'll probably get a better price from an independent shop).

As a sidenote, to be sure it wasn't a wheel bearing, if you hear it quiet down in a turn one way but get louder in a turn the opposite way, it's likely the wheel bearing. If you turn left at speed and it gets louder, then it's the right bearing (since you're loading up that side of the car). If it gets quieter in a right turn, it's the right side (you're unloading that side of the car and not putting as much weight on it, so it doesn't drag as badly). See if you get that symptom just to be sure that the wrong side front wheel bearing wasn't changed.

SOURCE: Whining Noise

Hi, this sound is most likely coming from the power steering pump. I would first, check the power steering fluid level to see if it is full. if its not at the full mark, add some fluid. If the fluid reservoir is full upon inspection and the whining continues, the pump may be damaged and the pulley on the power steering pump could be slightly out of sync with the pump housing.

The second issue could be belt slippage. i would do a tension check on the drive belt and pulleys as well. make sure there isn't any ware and tare on the belt and make sure the tension is to specs.

Please rate and god bless:)

Ring and pinion noise for sure,yes. Check for play right at the yoke where the drive shaft goes in.
I've seen a few fords where the pinion nut was loose and after re torquing they lasted another 100,000

I ve got a kalos 1.4sx 2008 and i ve got problems with the brakes. The brakes ''crunch'' when i m bringing the car to a halt,even on dry roads. The abs warning light has been on a couple of times but...


The Chevrolet/GM autos rely on a Kelsey ABS actuator system that is electronically controlled. I know its hard to describe sounds, but is it possible the crunch is a hum? If the ABS light comes on and goes off after restart it means one of two things. That the ABS controller is going bad or the speed sensors on the wheels have come loose or gone bad. Under your hood there is a fuse compartment that contains the fuse that controls the ABS system on your vehicle. Its a 60 Amp fuse and large.. Look in your owners manual for its location. . Check it with the vehicle OFF to make sure its not blown or cracked. Leave the fuse disconnected and start the car. The ABS light should STAY on as well as the parking brake light. Test your brakes by pressing down on them while the car is in park and not moving.. do you hear the sound. If you DONT hear the sound then the ABS control module is causing the brake pump to work continuously and thus your "noise". YOu can confirm by placing the fuse back in place and then listening to the car about where the drivers door is... do you hear a hum? If so you can leave the fuse disconnected to deactivate the ABS module. The brakes will still function you just WONT have ABS capability. Confirm this with a very slow roll from park or neutral and press brakes to stop. If you dont hear the noise or a hum, reconnect the fuse and take the car for a drive. Turn to the left and right while applying the brake at an intersection.. vehicle in motion slightly. Do you notice that the ABS light or noise occurs turning one way or the other or both? If it comes on during the turn then the ABS sensor in that wheel or both wheels need to be inspected and possibly replaced. Finally, you need to inspect the brake pads for wear..typically however brake pads have WEAR INDICATORS built in and will start to SQUEAL when you apply the brakes telling you time to replace pads. If its a squeal and not a crunch then have pads replaced. Finally, be sure and make sure you dont have any rocks or road debris within the brake area or between teh pads and the rotors. That would be your final area to review for a CRUNCH noise.

I changed the brake pads on a 05 equinox


Did you bump the ABS pickup at the wheel hub when you changed the brakes? Or are the wires maybe nicked? The noise is normal and might go away depending on the brake pad type you replaced with. The ABS problem might be caused by you.

My Chevrolet silverado ss abs light came on?


Take the wheel off and check the brake pads, they are probably worn down, and the metal backing on the disc brake pad is rubbing against the rotor.If that is the case, the rotor will need to be replaced, or turned down if it isn't too bad.

Abs light


This is a (4) four wheel sensor system and more than likely one of them has failed. This will cause ABS module to turn on warning lamp and make the brake pedal 'act up' under the right conditions.This 'acting up' is the ABS system getting a false signal that a wheel is not turning the same as the others when it actually is. Have it scanned for codes and a streaming data scan on a road test under the same conditions that you are experiencing the 'act up' to pinpoint the fault. Hope this helps! Please rate me.
