Perhaps this is a wee bit silly, but how does the yoke off of the back of a ZF tie into the driveshaft? I am replacing a M5OD with a ZF and the driveshaft just slides into the back of the M5OD.

Am I missing something obvious?

Thanks,

You need a new drive shaft that has the splines that allow the shaft it to adjust for different lengths whent he suspension travels.

 

Hi again Bob,

If I get a ds from a 250, will it be a one piece, and will it bolt to an 8.8?

Thanks,
Mike

 

It all depends on what set up you get the drive shaft from. The F250 came with both the Zf and the Mazda trans and depending on the year it could be a T18. I think it's called a T18. It's a 4 speed tranny but 4th gear is an OD gear. Which means different tranny lengths equals different drive shaft lengths.

The F250 will have a 10.25 rear axle and if early enough it could have a D60 rear axle and they are both different than the 8.8 in pinion length and the yoke size. All though one may find an offset u-joint to fit the drive shaft from an F250 to an 8.8 axle I have never done this but I have found offset u-joints for other mustang related type swaps.

Even if you try the swap with the 9 inch rear axle the same applies to it as it does to the 8.8.

I have also seen F150 trucks with a carrier bearing in the drive shaft and I have seen them with out a carrier bearing. My guess would be this holds true for the F250 line as well and this would add one more piece to the puzzle.


Grab a tape measure and try to match something up. That's more than likely the best thing you can do other than just getting a drive shaft made to fit your application.

If you have to have one made find a shaft with the splined slip yoke or two pice shaft that is longer than you need and just have it cut to length.
