Applications

Tech Note 1: Shim Thickness
Typically, pinion depth shim thickness will not need to be changed if you are doing a simple rebearing job. If you are changing gear sets using genuine Dana gearing, you can use the +/ - numbers etched on the new and old pinion heads to modify the starting shim pack thickness. To install aftermarket gear sets or a Dana gear set in a bare housing, you will need pinion depth setting tools to determine the starting shim pack thickness. Always check the tooth pattern to verify your pinion depth setting.

Tech Note 2: Pinion Depth/Preload
Pinion Depth must be set before setting pinion preload. Dana 70 and most Dana 60 axles use shims located between the pinion stem and outer pinion bearing to set pinion preload. Pinion preload sets the amount of torque required to rotate the pinion and it is measured with an inch pound torque wrench. Increase shim pack thickness to decrease pinion preload. Decrease shim pack thickness to increase pinion preload.

Tech Note 3: Dial Indicator
Pinion Depth and Pinion Preload must be set before calculating the differential shim pack thicknesses. Use a dial indicator and QT1098 (Dana 60/70) or QT1099 (Dana 70HD) Master Bearings to determine the amount of shims required to get the correct gear lash and differential bearing preload. See TM4400 Pinion and Differential Bearing Service On Dana-Spicer Monobeam Axles for the correct differential bearing adjustment service procedures.

Tech Note 4: Bolt Pattern
Dana Spicer solid beam Model 50, 60, Super 60, 61, 70, 70B, 70U, 70-2U, and 70HD axles all use the same bolt pattern for the differential cover so trying to identify what your exact axle model is can be difficult. In most cases, knowing the year and truck model will narrow the search considerably, but the best way to ID your exact axle and internal parts is with the Bill of Material number that is stamped on the right axle tube on mid 1980's and older axles or on a metal tag affixed to the differential cover by two cover bolts. On 1990's and newer Ford axles you may also find the BOM number on a decal stuck to one of the axle beams.

Tech Note 5: Tempered Shims
Up until the 1990s, Dana axles used mild steel shims in 0.003", 0.005", 0.010", 0.030" thicknesses which made building precise shim packs easy, but the mild steel shims had a tendency to tear from the torque of newer diesel and V10 engines. Dana switched to tempered shims in varied thicknesses of approximately 0.010" to 0.042". Set up takes a little longer because you now have to measure every shim, but durability is much better.

Applications:
Fits Dana 60 and 61 axles using shims to set pinion rotating preload (mostly 1993 and prior)

For all Dana-Spicer Model 70U and Model 70-2U (mostly mid 1980's 1985, 1986, 1987, 1988, 1989, 1990, 1991, 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002)
