Ford Bronco Pinion Angle Diagram - Drive Shaft & Pinion Flange Angles

This is a simple CAD-style annotated diagram illustrating driveline (pinion) angle geometry, uploaded to a 1995 Ford Bronco gallery. It shows two intersecting lines: one representing the pinion flange at 18 degrees, and one representing the drive shaft at 22 degrees. The included angle between the pinion flange line and the drive shaft line is dimensioned at 87 degrees, and a note explains: 'THIS ANGLE IS 3° FROM BEING PERPENDICULAR. SO IN MY THINKING I AM GOOD WHERE I AM.' The document appears to be the uploader's own working sketch used to evaluate whether their measured pinion angle relative to the drive shaft is acceptable, the reasoning being that a 90-degree (perpendicular) relationship would represent zero operating angle, and their measured 87 degrees puts them 3 degrees off perpendicular (i.e., roughly a 3-degree U-joint operating angle). A reader can learn the specific measured values (18° pinion flange, 22° drive shaft, 87° included angle) and the owner's conclusion that the current setup is acceptable. The diagram contains no part numbers, torque specs, or explicit vehicle/year identification; it is part of an album that also includes radius arm and bracket dimension drawings, suggesting a suspension lift or drivetrain modification project.
