I agree the rear end is not the source of the noise, try changing the fluid first in the transfer case.

Yes i would say it is a selonoid in the trans or a bad electrical connection. Get under it and pull the electrical plug off trans. If it looks corroded clean it with electrical contact cleaner. Be Very Careful when hooking it back up.Do Not force connection back together or you will bend pins.

It probably needs to be reprogrammed by the dealer or by an aftermarket shop that has the capability.

Try turning the key while jerking the wheel left and right and depressing the brake pedal. If that won't work try another key.

What kind of feed back ? Does it get louder with RPM . Ignition system can also cause this . But just to be sure have the alternator check for ac voltage ripple . Ripple voltage is when the DC voltage varies between (for example)12.5 Volts and 13.5 Volts, and does so rapidly. Technically, an alternator produces "alternating current", (hence the name, 'Alternator') and that AC voltage is converted to DC by running the current through a bank of "diodes". Alternator Diode Check and AC Ripple Check

Check to make sure your battery terminals are tight. You will be amazed how many problems start there. You can also remove both connectors and and clean the terminals very well. Get some dielectric grease from the auto parts store to help prevent oxidation which will also cause problems.

It is held on with nuts... just get under it and look... its not hard..or complicated...just do not remove the last two nuts or the bumper will fall when you least expect it to..(SAFETY).. it WILL cut you bad if it falls on you.. get a friend or remove carefully...

The charging system on your vehicle is controlled by the PCM powertrain control module . The PCM will send a message to the instument cluster on the class 2 serial data network to turn on the charging light if it see's or think;s there is a problem with the charging system . Should have a code stored . Have autozone check for codes.

Most likely not in the cab. Check the harness on the neutral start switch on the transmission. That is what turns on the lights when you shift into reverse.
