You will have to have a dealer flash the BCM. If the BCM didn't have the same Vin identification code, the used one will not operate correctly. Each truck has its own unique Flash program

What you have is that the Amp that come equipped with Truck has to be unplugged and bypassed. The factory radio has a security code built in and uses a amp to push the speakers. As long as the amp is hooked up,you will not get any sound from speakers

Usually when these Gauges go out it is because of a faulty BCM( Body Control Module) The BCM controls all dash instruments . If it is the BCM you will have to get a dealership to flash the new one. Before doing that though check all fuses under hood and inside. It should say gauges or BCM

Assuming you have looked at all your fuses in that system, First disconnect and clean main ground on battery. Clean positive connection too. Reconnect ground wire last. If problem persists, have the alternator and battery tested. That is often a free service at chain retailers. If everything checks out, instrument pod my have issues. That is a more expensive fix because it must be removed in one piece and sent off for repair.

With key off unplug the mass air flow sensor and try to start the vehicle. If it starts and runs fine, try cleaning it with mass air sensor cleaner, and plugging it back in. If cleaning doesn't solve the problem it may need replaced.

Hi, if your referring to the front differential , then it is threaded in place just simply unscrew the old and install the new one. You don't need to worry about anything else.

Melinda, I would recommend having a evap test performed. The tech would do a smoke test for possible leaks, and an on/ off test on the vent valve. Often times the vent valve is faulty. The parts are in stock at Napa.

I would remove the rear drive shaft and apply silicone grease to the slip joint. (Inside of front yoke)

It may be in the steering box and pitman arm which is the arm that comes off the steering box, if you have a rack in pinion set up you may have to have it check out as well front end alignment should have caught that.. Idle arms should also be checked. If not then look into steering Colum tilt wheel make sure nothing is warn out and working properly. Depends on year and make will determine what setup you have which was not mentioned so Hope this helps God bless
