Tech Note 2: Placement
For all 1973-2006 Jeep Dana 30 front axles that DO NOT HAVE vacuum controlled CAD, two identical axle shaft seals are used. One QU40307 Seal is pressed in the inboard end of each axle tube next to the differential. It is impossible to replace the seals from the outside! You MUST remove the hubs, axle shafts, and differential to replace these seals. QT1032 differential case spreader is definitely recommended but not absolutely required for differential removal/installation.

Tech Note 3: Clean
After removing the old seals (See optional Removal Tools QK4647, TS4863, QT1144), thoroughly clean the axle tubes to remove crud, grit, and scaly rust.

Tech Note 4: Lubricate
Lubricate the Seal Lips with clean grease before installing the differential to provide initial lubrication. Install the axle shafts dry to minimize the chances of picking up residual grit inside the axle tubes as you slide the axle shafts into position.

Tech Note 5: Original Seal
The original seal type used in 1972-1978 Jeep Dana 30 front axles was QU40057 NOK Seal which requires QT1079 Installer. Dana has discontinued QU40057 Seal and replaced it with QU40307 Seals included with QK4800 Kit. QU40307 directly interchanges with QU40057. If you are a restoration purist and want to replace your 1972-1978 Seals with the same type as original, you can still order QU40057 while supplies last.

Tech Note 6: Adjustable Depth
QK4931 uses QT1139 and QT1203 adjustable depth installers which allow you to offset the seal to miss a worn spot on the axle shaft. This is a valuable feature, however, YOU have to determine the final depth of the seal. If you are not careful, it is unlikely but possible to seat the seal too deep with which can put the seal beyond the machined seal surface of the axle shaft.

Tech Note 7: Inspection
When replacing your inner axle seals, ALWAYS inspect your Ball Joints, Axle Universal Joints, Differential Bearings, Wheel Bearings, and Spindle Bearings/Seals for wear or damage. The extra time needed to replace these components is minimal since you already have the axle apart to do the axle seals.
