Installation notes
The shims are fitted between the pinion bearings (inner and outer set) to accurately adjust pinion depth and bearing preload. During every differential overhaul, the shims must be carefully measured using an inch-pound torque wrench to achieve correct preload (14-19 inch-lbs). Adjustment requires technical knowledge and specialist tools — set-up bearings are recommended.
Compatibility
Please note: This set is suitable for Dana 25 front axles, Dana 27 rear axles and Dana 44 front and rear axles adjusted with shims (not with crush sleeve). Always check which type of differential your vehicle has before ordering.
Historical context
Dana axles were extensively used in military vehicles during WWII — the Dana 25 in the front axles of Willys MB and Ford GPW, the Dana 27 in the rear axles of the same vehicles. Later, Dana 44 axles were fitted to subsequent models such as CJ-3B and M38A1. Correct adjustment of pinion bearings was and remains crucial for reliability and longevity.
