My 2003 GMC Envoy has a very loud humming in the front end along with a sound of what sounds like metal tapping when I turn my wheel. It is almost like a train ride with the noise in vibration, what the fetch could it be?

SOURCE: 2002 gmc envoy front suspension noise

Thanks for providing that information.
At 65K I would first suggest changing shocks. Yes, that is enough mileage to have them beginning to get "softer" which will increase suspension travel and noise.
Even though they may test good (usual test is jumping on the bumper to see how it responds after bouncing) but that really doesn't apply to shock/strut combinations.
I would suggest a higher then factory grade replacement shock. Do realize 60% of the weight for that vehicle is in the front.
Next, there is always some, what they call "spring seating" as a vehicle gets older. You will notice it more when the suspension is in a turn, going over a bump. The spring moves / rotates in the seat, and you will hear a sometimes loud popping or clicking noise.
Bushings are probably best left to the professionals, unless you happen to have a well equipped shop at home.Same goes for the struts. You will need a good spring compressor to be able to change them, and you will need to have an alignment done after changing them. Doing the bushings at the same time is easy once the struts are out.

Since it is 4WD you mine want to test the front CV joints also. If you have access to a lift, put it in the air so all 4 wheels are off the ground, and running it. Listen to each front wheel to see if you can hear any CV noise. Please be very careful doing this. Doing it incorrectly can result in injury.

What you want to do more then anything is take this a step at a time. When you hear a noise inside a car, it can sound like it is coming from one place, and you can find out later, it is somewhere else.

I think a Haynes manual is going to be a good guide for you on this problem.
Take you time, and be very careful doing this kind of work. If at anytime you are not 100% comfortable doing the work, consult a professional.
Sorry I can't be more help as a simple fix, but I'm limited diagnosing any further without have the vehicle at my access.

SOURCE: veh wont start

by looking at the wiring diagram for your truck. the pcm1 fuse only feeds the pcm so most likely it is a grounded wire between the fuse block and pcm. follow the wire harness closely between the two and see if its grounded somewhere. also try disconnecting the pcm and see if the fuse still blows. that would isolate the problem to the wiring. it is highly unlikely that the pcm would cause the problem.

SOURCE: Ticking sound

Gm will tell you this is normal lifter noise if it from the top of the motor. It could be from the exhaust but you would hear it from under the car more. I do not care for the responce from GM but they say it is ok.

He's probably talking about the wheel bearings located in the front hubs. They can wear out over time and cause a humming sound as well as vibration. Any brake shop will look at the truck for a free brake inspection. If they determine it's just a wheel bearing, it shouldn't be a big ticket job.

I am getting a definite road hum off the front of my 2003 Envoy. when I rotated tires it seemed to quiet it but than returned. I suspect wheel bearings but it doesn't get louder when turning the wheel...


Usually this is a sign that you need an alignment. Do previous front tires show any wear on the corners? My guess is that the noise returned when the new front tires "broke in".

2004 gmc envoy engine tapping sound, it has plenty of water/antifreeze, and plenty of oil.


We have the same tapping sound on our 2003 Envoy six cylinder engine. I believe the sound is coming from the radiator fan clutch assembly. When the engine reaches its operating temperature and the fan clutch engages, the tapping sound goes away.

Whooshing sound coming from front tire


Sounds like a few things. Flat spot on the tire. Something caught in the tread. Jack up the vehicle and turn the wheel by hand and see if you can recreate the sound, if you can you will find the problem.

sounds like the wheel speed senser is not working properly when you are in all wheel drive the computer uses the brakes to keep the all wheels rolling at the same speed for good traction if one speed senser is reading that right side front wheel was going faster than the others it would activated that brake via the antilock brake system
