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: replace starter on 2002 GMC Envoy SLT

check to see if the starter itself is getting a signal to crank. youll need to use a test light and have someone else try to start the vehicle, while you probe the wire to the starter to see if it is getting power. if not, check the starter fuse to make sure its not blown, as well as the starter relay to make sure that is good too (very common on gm's for bad relays) if the fuse and relay are good, but your not getting signal, it is an ignition switch problem.

If your 2002 gmc envoy or sierra will not even turn over with a kown good battery try starting it in nuetral then go back to park and try starting again. There is a park nuetral safety switch that can malfunction. Turn the key on then shift into nuetral, then turn fully to start.

SOURCE: I need to know how

It would be to hard to tell and show you over the computer.
The best and easiest way for you is to buy a Chilton manual for your car at the autoparts store. The book runs about $20
This book is a do-it-yourself bible. It will show you everything you need to know on how to do maintenance and repair on your vehicle.

SOURCE: 2002 gmc envoy shuts off when i turn on the ac whil ideling

If it does it when idling I would suspect an IAC motor (Idle Air Control). If it is opening too slowly the added air the motor needs will not be supplied fast enough and the engine will kill.

It could be other things also but this is where I would start.
