i bought a 2001 aluminum driveshaft, it was 100% the same length as my 1996 steel driveshaft. It has the same u joints, spline, etc it just worked.

I dont know how or why but it works without the spacer.

The driveshafts are very close but not exactly the same length unless it was custom made, that is a fact. It will work it just does not fully engage the splines. The drive shaft is shorter and the aluminum ones have an extended tail housing. Here is an example of when looks the same goes wrong. The bolts "looked the same" https://youtu.be/jKlZ2enWQbY

You misunderstood my post. The driveshaft was exactly the same length and the spacer would not even fit behind the aluminum shaft. We tried and it wasnt going to work.

It is a ford shaft and has the 3 lines on it, had ford u joints and yokes. I was really confused and so was chris at ADTR. I have a pic of both of them next to each other somewhere.



The stripes on the bottom are faint but they are there. It came out of a 2001 P71 car. It went on our 1996 crown vic p74 regular civilian version.

i dont think its a mmc driveshaft but i really dont know honestly. It does not have the police or the other writing on it.

Given the aluminum driveshaft appears completely stock, I suspect your steel shaft was shorter than normal.
Do you still have the car? Or know if it had a long or short tail tranny?
One theory is the transmission was swapped for a long tail, and the steel shaft was shortened to accommodate.

I have had the transmission out multiple times, it's a factory short tail trans. I had another built transmission put in and it's a short tail transmission. The car was 100% OEM. The steel shaft worked with two different transmissions. The only unknown is the aluminum shaft. According to the scrapyard it came out of a 2001 p71 so unless there is another OEM shaft that is the same length as the crown Vic steel driveshaft, I have no idea what is going on

hkerekes,

Where did you buy your aluminum driveshaft? I've bought six from salvage yards online from out-of-state and in-state and all had really bad spun caps making them useless. I can't seem to find one that isn't shot.

Junkyard up in Wisconsin, but i saw it in person. It had what looked like original ford u joints on it. They were not spun but were a pain to get out. I travel for work so i get to find random parts all over the country when i have free time.

Quick update.

The shop and I kept arguing back and forth about whether the driveshaft was long enough or not without the spacer. They ended the argument by claiming they cut the driveshaft and extended it. I was suspicious because I can't see any weld marks that aren't factory.

I measured the driveshaft the other night and found it was indeed the CVPI factory length of 55.75". The factory length of a Grand Marquis Steel driveshaft is 56.5". This means the shop is full of it and they were lying about extending the length of the driveshaft because they didn't want to install the spacer. They even charged me for "driveshaft repair" as a line-item on my invoice!
