Installation notes
The Dana 25 front axle has a larger diameter on the inner right-hand side (passenger side). Therefore use 1× large U-bolt (A574) right-hand inner, and 3× standard U-bolt (A575) for the remaining positions (2× left, 1× right outer). Tighten the nuts in a criss-cross pattern for even pressure.
Compatibility
Does NOT fit M38A1 (too short). For later CJ-5 models, different part numbers are required (A1097 or 808988).
Historical context
The Dana 25 front axle was used on all Willys MB, Ford GPW, CJ-2A, CJ-3A, CJ-3B and M38 military and civilian jeeps until the early 1960s. The asymmetric U-bolt configuration compensates for the varying axle diameters.
