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.
It was an option.
Yes. Look on the rear axle for a tag. It will be bolted to the rear cover. If it has the numbers (example) 3 L 27, or any combination of numbers with a L as a second digit it should be a locking type differential. These are fairly uncommon in non Police vehicles. The locking differential can be found on non-Police Crown Victoria and Grand Marquis models which came equipped with the optional trailer-towing package. Also, if the door sticker is still on the drivers door, it should have something that says "Axle" with some numbers below it. you can see which differential you have with that incase the above mentioned tag is missing.
Not normally, but it was an option.

5.0 pints ( 2.4 liters )
Not usually. Only if ordered from the factory. But, it does have a anti-slip in the transmission.
That will depend on which differential you have. There is more than one. Find the metal tag located under one of the differential cover bolts on the rear end housing.
They need both a positive connection and a negative connection to function.

You need to remove the fuse for it, for that you'll need a manual for that model and year. The above answer is incorrect, sure you could do that but!!!! Check in the glove box to see if there is a round push button switch. If there is and it wasnt removed- this button will disable the traction control. To verify that it is off there will be a light that says traction control that will light up on the instrument panel. It will reset back to ON everytime the car is shut off. This is on a 1998 p71 Crown victoria, an LX Vic should be the same.
Yes
