We swapped the axle into the Jeep on a weekend, and we were pleasantly surprised to find that our existing front driveshaft was long enough. We knew that the snout on the Dana 44 was about 11⁄2 inches longer than that of the Dana 30 it replaced, but we also went from a high-pinion Dana 30 to a low-pinion Dana 44. We adjusted the caster of the axle until the coil springs were straight and we had about 5 degrees of positive caster. At 6 inches of lift, that left us with a slightly undesirable driveshaft angle. We have a vibration when the front hubs are locked in around 50-55mph but we are planning on lowering the Jeep by at least 2 inches so for now, we unlock the hubs between trails if we have to get back on the road.
