yes it has a rear differential,it"s rear wheel drive! If it was an old cop car then yes it has a posi-trac rear end with 350 gears. If it is a standard crown vic with a 302 engine then it does not have a posi.If it has a 351 winsor engine it is an old cop car. The easy way to make it a posi is to buy a rear from an old cop car at the junk yard and install it in your car!!

I believe the Trailer Towing package also provided a limited slip differential. Are you certain about the gear ratio's being 350, not 373?

Please note that in 1989, Ford Crown Vic cop cars were also equiped with the 5.0 litre 302 H.O. motor. The only REAL way to tell a 1989 standard model from a police model is by checking the VIN number thru the windshield. If the number contains "P72" then it is a police model, if it contains "P74" then it is a standard model. The easiest way to tell if your ride has Posi or not is to check the rear differential cover for a limited slip tag. Good luck.

1. remove door panel trim. The regulator is riveted to the power window motor, with 3 large rivets. Three other large rivets atatch this whole assy to the inside of the door. It is important to drill out the rivets holding the regulator /and motor to the door, and leaving the motor attached to the regulator, because the regulator has a heavy spring that will be released if the rivets are removed. To separate the regulator and motor you need to drill a hole in the regulator arm, and place a nut and bolt through the hole, at a point that will keep the spring compressed once the motor is removed. Now that the regulator is secure, the rivets on the motor can be drilled out, and motor separated. The new motor needs to be bolted onto the regulator, or riveted. The factory rivets are large, and it is doubtfull you will find such large rivets, or a rivet gun for that purpose, so stick with bolts and nuts. reinstall the complete assy, and again bolt in the whole assy inside the door. bolts and nuts are a real pain in the butt to use in such a confined space, but again rivets of such a large size are hard to find, along with a real large rivet gun. I reccommend using nylon locking nuts so they will not come loose after a certain amount of time and vibration. A set of rubber door stops is also usefull in holding the window glass in the up position while work is being done.

You will find a rivet gun that size at Habor Freight cheap china made but will do the trick.

If you pop the hood, on the back of the headlight housing, there are some wires with a snap on or twist on connection. If you disconnect them as you pull them out the headlight is attached to the other end of the connection. Make sure not to touch your new bulbs with your hands because the glass on a headlight bulb is designed to run at a high temperature, but the oils on your hand get hotter than the temperature they are suppose to operate and will cause them to blow or bust. If you do accidentally touch one, just wash it off with alcohol.

On mine it was the fuel pressure regulator. I have a 4 cyl engine with 185 K miles on it. Over the life of the car, I have replaced the regulator several times. I tried an aftermarket regulator, that lasted only a few thousand miles. The factory equipment unit is more but worked about 5 times longer.To check it, I would have the car running, cold, and pull the vacume line to the regulator. All but one time, gasoline would squirt out of the port where the vac hose hooks up, to the regulator, so BE CAREFUL, RAW GASOLINE. One time I didn't have gas, but it still was the problem. Apparently, the fuel rail gets hot enough to trash the diaphragm inside the regulator. .

Change your tranny fluid! you could be slipping to!

All 1998-2002 Pontiac Firebirds/Trans Ams take 24" replacement windshield wiper blades on both sides front.

What happened to Firebirds is that they were outsold by Ford Mustangs and didn't give Pontiac a big enough market share in the segment. In other words, the bean-counters killed it. It will come back when someone comes up with a concept that they can convince Pontiac management will make money. In the mean time, check out the GTO, or the soon to be introduced Solstice to get your Pontiac "excitement" fix. Darkfriend adds:

They quit making them in 2002, along with the ever popular Camaro. The Camaro has been reintroduced in 2010 and has some characteristics of both Camaro and Firebird. The Firebird will likely never make a comeback.

or the motors are dead...Pop the hood...turn your headlights on...is the grey/black knob just spinning? Replacing the motors is really east it's all 10mm...if it's your first time you may want to pull the whole headlight mount out just so you can get a feel for next (trust me there will be a next time) == == First open the hood and try to turn the grey knob clockwise on top of the motor it may be located under a black rubber cover if that doesn't work look at the arms attached to the inside of the head light the bolts may have come loose last but not least your gears may be stripped in that case ck out this web site! Good luck! http://www.bfranker.badz28.com/headlightfix/index.htm

Open the hood and on the top of the headlight assembly there should be two pins. Turn them so they face the front of the truck and pull them up and out. Now you should be able to pull the whole headlight assembly out. Turn the ring on the back of the headlight ,unplug it and pull the headlight out. Install in reverse order.
