3.73 to 4.10 gears 2002 civilian vic
I kinda want to stop by a dealership and get a full oasis print out on my car, Im guessing i have 3.73 rear end...so after reading countless threads, i have discovered the 4.10 gears, sounds awesome. Im not a guru with shims, I do okay with crush sleeves, I have not done anything with an 8.8 other than outer axle bearings and and replacing bent axle shafts. Working for dodge now i have done a couple pinions and the torqe requeired is ridiculous the measureing torque to rotate and getting the shim right....Is the ring and pinion the only parts needed with a crush sleeve? on amazon its listed for $170. for just the ring and pinion. would i need a runout gauge and all that complicated stuff to figure out what shims are needed? If it were not to hard a job i would jump on it! DIY would be a must. Id have to do it. wld be a longwait untl i could frkut the money,but hat im seeing is that th wld beone of the worthwhile mods to spend $ on.

amazon link-----> search "SVL 2020737 Ring and Pinion Gear Set for Ford 8.8" Axle"

Not sure about "SVL", but the Ford gears are cheaper...especially right now since there's going to be sales everywhere.
If you have a shop to work in, it will be easier. I did the rear in my Sport in my backyard since I didn't want to try and do it in the car on my back under it.
I had trouble setting up the gears for the wagon and had to take it to someone to finish it up. It's not that hard if you're mechanically inclined.

RE: 3.73 to 4.10 gears 2002 civilian vic
I think im going to hold off on the gears, id rather do it if i were in a rear end has to be rebuilt situation. I do have a slight leak on my pinion seal, and will be replaceing that soon. I was toying with the idea. seeing how much a tune costs, and the gears, Im gonna cool it and just geezer glide it and just try and keep the load light. thanks for the reply!

No Crown Vic EVER came with 3.73.
CVPI had either 3.27 or 3.55, civi in general had 2.73(3.27 optional, standard on HPP or Sport)

LOUD EXHAUST IS FUN! AM I SHOUTING?

Also of note, the 3.27 can come open or locked as denoted by the L on the diff tag or an X code in the VIN. Wiki says it'll be an X5 but Frank's is actually X15. Think it's the X that's important, not necessarily the following number.

X15, never heard of that. DK is 3.55 trac-lok though.

That link there has a door sticker decoder, look at the axle code on your door sticker and it'll tell you what you have.
If going to 3.73 or 4.10, it's recommended to use an aluminum driveshaft
