More axle info: Your rear axle is shown as a Rockwell G161, the front carrier assembly is a Rockwell E100. Ratios 5.29, 6.17, 6.80; 7.20 to 1. Unless its been changed the transfer case is listed as either a Coleman 22 or Coleman 42, both have two shifters. The difference being is the 22 operates like most common transfer cases, the 42 operates with full differential control between front and rear, which can be locked for full 4WD. Hey who knew, early full time 4WD.
Here's your front axle specs.
Best regards,
