I picked up a spare axle shaft a while back thinking both sides were the same. Now I need the opposite side and I am not sure which one I currently have. Anyone know the length of each shaft? The tech library doesn't say anything about the 31 spline shafts.

I didn't ask for your life story, just answer the question!
I found this:

Explorer 8.8 Measurements:
Weight (complete assembly w/ brakes etc.): 174 lb.
O.D. of tubes: 3.250".
Tube thickness: .250" (some are .188”!)
Ring gear diameter: 8.800".
Ring gear bolts: 7/16" dia. (qty. 10).
Pinion diameter/splines: 1.625 / 30.
Axle shaft/splines: 1.320 / 31.
Rotor thickness (where it mounts to axle is .250").
Overall width 59.625" (the F8.8 is .950" narrower then a TJ Dana 35).
(The F-150 8.8 is drum brake and width WMS to WMS is 65.5”.)
Hole diameter for ABS sensor in top of housing: .811".
Bolt size (U-joint flange to yoke) is: 12 x 1.75 x 30 mm
Centerline of housing to C/L of pinion difference is 3.875" toward the P/S.
Pinion offset: P/S to C/L of Pinion, 27-3/4" (no rotor on axle), D/S to C/L of Pinion, 31-5/8" (no rotor on axle). (this measurement is 2.5" more offset to the P/S then a TJ Dana 35).

Take a 2nd look:


P/S to C/L of Pinion, 27-3/4" (no rotor on axle), D/S to C/L of Pinion, 31-5/8" (no rotor on axle)
They should be about 27 3/4" and 31 5/8". But I've also seen the long side listed as 30 5/8" and the short side listed as 27 1/2".

Thats a good question guys - reviving an old thread.

I have a 31 spline FX4 level II rear end - I am looking for a set of Moser axles. But they need to know the length of axles that I need.

Would those 28 spline lengths be good for me too?

Pull the shafts and break out the tape measure. They are the same legth shafts as the 31 spline expo axles AFAIK.

Carefull - the Explorer axle is 1 1/2" wider than the '93' and newer Ranger, check tech library.

We're talking about the 31 spline ranger 8.8.. I'm betting it's explorer width too.
