Coyote Drivetrain Question

[ksack]

Im doing my research on a build I want to do but I can't find the answer to this. Applies to mustangs or F150s with a 5.0. I need to know the drivetrain alignment so I can get the axle housing shortened on the recipient car. Since the input shaft isn't centered on the diff housing, how do they take that into account? My understanding is that u-joints don't like two pinion angles...

The pinion flange isn't centered? I have a hard time believing that.

Correct. It is a Ford 8.8 from an Explorer. It is offset a little towards the passenger side.

Correct. It is a Ford 8.8 from an Explorer. It is offset a little towards the passenger side.

Are you sure? The Pinion Flange should be centered and 1 tube will be slightly longer than the other possibly

Yes, with respect to the differential housing only. Perhaps you guys are answering my question by saying that the axle is slightly longer on one side. I'm hoping someone knows for sure.

Unlikely

Do you know how you can know for sure?

In actuality you can go to some of the Axle Builder Sites and get some info for measurements on custom. Strange, Moser, etc.

Are you sure thats not the front axle?

I don't have anything with a coyote powertrain to measure it so no

Are you sure thats not the front axle?

Yes I pulled it in the junkyard myself.

Hopefully this will make y'all believers since we have digressed from the original question. Please let me know if something doesn't make sense. Found some pipe clamps my buddy has and used those as my "squares" since I don't actually one. Measured with respect to the pumpkin only. As you can see, there is approximately 1.25" difference from the posts to the center of the pinion, which means it is offset 0.625" from the centerline of the housing. I also looked up the axle lengths for a S197 Mustang and found them to be 1.13" different between the two sides, which would make the answer to my original question Option 3. That means the centerline of the axle vs the pinion center difference is 0.565 (close enough for me for not using a true square and a tape measure) and that accounts for the pinion flange being offset to the right (pax side axle is the longer one)
