I'm repacking my wheel bearings and doing general maintenance to my front diff. It's a D44 unit. I also need to change the seal in the end of the axle tube. I have the hub down to the spindle with the stub shaft loose in the spindle. When checking out the axle tube seal I wiggled the axle within the axle tube to see how much play is there and found about 3/32 to 1/8 inch up and down play. I'm referring to up and down play between item 18 and the tube in this exploded view. I assume 18 is a bearing/race assembly and 19 is a seal since I don't see a separate race in the diagram. Is this normal? The other side is still together and it has about 1/16th inch up and down play. Anyone know what's normal?
