Trouble connecting diff to driveshaft - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

Yeh, as the topic sez im havin a bit of trouble getting the driveshaft to reach the diff.

I just swapped my single spinner for a 3.23 LSD out of a EA Fairmont Ghia, everything bolted in fine...until i got to the diff.

The uni joints dont reach so i cant bolt it back together. I tried lowering and raising the car to adjust the distnace but they always seem to stay just out of reach.
This is first time i did this so maybe im missing something obvious.

Any help appreciated. Its the last thing i need to do to get my bludy car on teh road!

What kinda car are u fitting the diff *TO*?

its from an EA Fairmont Ghia going into a EA Spak. I checked the length of the diff housing and everything, they are exactly the same, even looks the same. Im thinking it could be something to do with teh suspension geometry like it has to be in the exact same position as when i removed teh diff.

I talked to 2 Ford wreckers and a diff specialist that said it would bolt straight up. You would think it would since its from the same model family.

Was no issues when we changed the diff in my EF...

Freaky mate.. Must be the way your diff housing and diff sits in the arse of your car..

when you guys reconnected it did you have the car raised with the stands supporting the diff or supporting the body?

Does the height of the diff even make a difference?

This problem is shitting me up the wall, i know it should be simple but its just not happening for me :(

from memory we jacked the diff up and the tail shaft was one of the last things we did.
it will make a difference if the diff is hanging too low.

yea i think thats it.

when i tried to put it back in i tried putting the jacks under the body and also putting it uner the rear axles but i didnt support the body and jack the diff, it didnt reach or something cause i had em too high. Cool, i think i know wat angle to attack from, thanks guys.
