Part of what beat the bearings up in my 9" was a terrible pinion angle.
I now have it set on 4 jack stands with the frame level. I have the rear end set to give the frame 5" clearance from the floor. I will set the front to give a 5" clearance from the frame to the floor (it's within a 1/4" of that now). This gives the
oil pan about 3-1/4" off the floor.
The transmission is running down hill to the rear by 1 deg.
With the pinion yoke setting 1 deg down hill to the rear by 1 deg, this puts it parallel to the transmission. The drive shaft is running down hill from transmission to pinion 13.2 deg. This gives a 14.2 deg angle on the yokes!
I don't like the idea of running the
oil pan any lower to the ground.
Note: With pinion set at zero not the (1 deg mentioned above) the pinion is 3" lower than the transmission. The drive shaft is 10-15/16" long from center of U-joint to center of U-joint.
Advise please.
