AWD axle ratios
I tried a search but didn't find what I'm looking for. Did all of the AWD vans have 3.73:1 axle ratios or did Ford put 4.10's in any of them? I was looking for 4.10's for the Dana 28 and was hoping that the factory used them at one time. Does anyone know if the gears from the Ranger/BII Twin Traction Beam Dana 28 are installable in the Aerostar's axle? I would think they should, but there may be significant differences in the gearsets between the two iterations of the Dana 28...

I was under the impression the 3.73 was universal to all Aerostars, but I seem to recall several people posting last year about having limited slip rear diffs with a different ratio, possibly the 4.10. I do know different 3.73 rears have different numbers of axle splines, so you may want to find out if the Ranger/BII have the same 28 spline shafts as the Aerostar.

Spline count wouldn't have anything to do with I'm talking about. I'm not looking at swapping over the axle assembly from a Ranger, I'm talking about the ring and pinion gears themselves. Removing them from a Ranger/BII axle and installing them into the Aerostar axle. The van's differentials (which contain the splines) would stay with the van.
BTW, the 7.5" axles are all 28 tooth splines. That's all that Ford ever used in the 7.5". If there is a difference in splines with some axles, that would between the older Dana axle and the later Ford axles (both the 7.5 and the 8.8 used the same 28T spline in this vehicle). The BII and Ranger also use the same axles and also have all 28T splines. The only Ranger not to is the current FX4 L2.
