Pinion and driveshaft clearance questions

You have enough drop in the rear this might be an option for you. You can buy shims that go between the rear swing arms and axle. It was easier for me to just remove the mounts and weld in new ones.

And also true with 4x4s, I didn't think of that either. Especially on short wheelbase jeep, operating angles must be crazy.

Extreme drops (>6") can fall into the same realm as lifted 4x4's.

The old adage that if the motor/trans is tilted/pointing down @ X°, then the rear pinion needs to be pointing-up @ x° is not correct IF the pinion is equal to or above the trans output.
