Hi mate,
Using the following method:
One wheel jacked up off the ground. The other wheel on the ground and the propshaft marked. You should observe the following:
41 turns of the prop = 18 turns of the wheel = 4.55 diff
37 turns of the prop = 14 turns of the wheel = 5.286 diff
43 turns of the prop = 16 turns of the wheel = 5.375 diff
38 turns of the prop = 18 turns of the wheel = 4.22 diff
Those figures correspond to COMPLETE revolutions of the wheel & propshaft and are calculated using the crownwheel & pinion ratio.
So if you have 4.22 then it's the 1098 axle. 4.55 is the 948 axle and the other two are series 2 or series MM ratios.
