tech note

QU40177 Gear Set has 45 teeth on the ring gear and 11 teeth on the pinion gear. It is a matched, standard cut gear set that fits most Dana 44 axles that have the pinion gear located below the axle center line. The pinion shaft is the 26 spline configuration used on Dana 44 gear sets since the mid 1960s.

tech note

QU40177 will not fit Dana 44 series axles in 1966-1996 Ford F100, F150, Bronco or 1977.5-1996 F250. These Ford models have pinion gears mounted above the axle center line and require a reverse spiral gear set.

tech note

If you are doing a gear ratio change, you will also need to change your differential case (the part the ring gear bolts to) if your current ratio is 3.73 or faster. Faster gear ratios have a larger diameter pinion gear than slow ratios so they require a differential case with a different offset. For the Dana 44 axles that can use this gear set, the differential cases are different for 3.73 and numerically lower and 3.92 and numerically higher ratios.

tech note

Ring Gear Bolts are designed to be used once and only once.

tech note

Pinion preload is set using shims on 1993 and older Dana 44 axles.
