Dana 44 shaft length

So I'm planning on building a one ton dana 44, and I need some info. What is the difference in shaft length if the pinion yoke is centered on the axle? I would like for my driver and lassenger side shafts to be the same length for ease of replacement. From what I've found on the XJ 44's( they seem centered) the difference is a 1/2 inch longer on one side, something like 28 5/8 and 28 1/8.

Also is there a problem running with the pinion slightly off center if I do this?

Dana 44s are generally considered 1/2-3/4 ton axles.

In order to have equal-length axles, the pinion will have to be offset. Many axles out there actually have offset pinions.. no problem.

Do you know how much the offset will have to be with a Dana 44?

Not off the top of my head. Over on Pirate, I think Billavista wrote up a D44 article that may have the info. I know he did a great writeup for the D60 several years ago..

Okay thanks. If I recall correctly the XJ dana 44 pinion is centered so I thing it may only be 1/4 of an inch offset

If you can that would be great! can i get driver and passenger shaft length, distance from flange to pinion on both sides, and distance from backing plate to where the tube meets the housing on both sides?

No longer has regular backing plates. It's got a disk conversion from a ZJ (IIRC).

Would likely be better off with a ford axle such as an 8.8 or 9". I had both eb9 and full size 9" I ran in my xj. Equal length shafts, the 8.8 is narrower than an xj axle I've always wanted to get one and use both long side shafts to stretch of out and have equal length shafts. D44's aren't that great and are a tad rarer, ford are a dime a dozen and stronger.

ltrail normally I would agree with you, but this is going to be a full float dana 44 with 14 bolt shafts

These are the measurements from the inside of the axle tube flanges-to the centerline of the pinion...

26.25" and 28"

Does someone make a large 30 spline 44 spool/locker? Both axles are 30 spline but 14v shafts are a bit larger diameter. Would be much better off doing a 609. Use 35 spline spool for the ford 9 and tube a 9 to use d60/70 35 spline shafts. I think it is a lot harder to do what im lead to believe you are doing. Furthermore, a d44 r&p won't hold up to 1ton abuse.

Why not just run a rear 60 or 14Bolt? They're relatively cheap. Many full-floater 60s are only 30 spline, so you'd need to search around, or bore the spindles for 35 spline axles.

14Bolts are cheap and pretty much bulletproof. If you're running big enough rubber, ground clearance isn't too bad, after you shave the bottom lip off.

While it is possible to build a pretty strong D44, a stock (read cheaper) D60 is still stronger.
