Thanks Terry

In the front of a Clymers ford BroncoII/Ranger service manual.

I have one... not in front of me ATM, but I know 6th/7th digits designate whether it's a 4x2, 4x4, reg cab, super cab or bronco.

What did you need to know?

with out crawling under it in the mud.. whant to know what axles they have. #s i found are 1989 axle =D4 and 1988 axle =44. is this just front or front and rear, they are both 4x4 Thanks Terry

CODE: DEFINITION:

42 3.45

44 3.73

47 4.10

D2 3.45 (limited slip)

D4 3.73 (limited slip)

D7 4.10 (limited slip)

On 4x4’s, there is a Dana 28 axle up front, until october 1989 (check your build date, you may have a 35) when it was replaced with a special Dana 35. The front axle should have the same gear ratio as the rear. The D35 is a stronger (than the D28) and can be swapped over from a Ranger, or exploder, (or newer BII, if not already equipped). The D28 can be re-geared; however, units with the 3.45 ratio, going to a lower (numerically higher) ring and pinion gear must use the appropriate housing. to tell a 35 from a 28, the bolts on the diff - a 35 has ten, and a 28 has 12.

All Bronco II’s came with a special version of the 7.5” rear, which has a capacity of 2640lbs. Other Ford 7.5” axle housings will NOT work in place of the BII unit; however, the rings and pinions from any 7.5 can be swapped into it.

I have a d4 code, trac loc in back, and open dana 35 diff in the front, 3.73 from factory.

hope this helps
