I installed new Adams drive shafts yesterday. Before touching the rear pinion nut I measured the pinion total torque to rotate and it was only 15 lb-in. I installed the new yoke and ran the pinion nut down with the impact wrench. I could feel it bottom and gave it a few more hits with the impact. I checked the pinion torque to rotate again and it was about the same. I couldn't feel any play in the pinion other than rotational backlash. The Dana specs for the Advantek 44 call for quite a bit more torque than this:
PTR: 13.54 - 21.42
PTTR: PTR plus 8.43 - 15.94
Is there this much difference between new bearings that have not been oiled and broken in bearing in oil? What have others measured for PTTR when installing new drive shafts. What signs should I look for that indicate too little pinion bearing preload?
