I built a 9" from the junkyard and have no need for a high pinion 3rd member. It's plenty strong for the 33's I run. I have about 15,000 miles on the rear axle since I finished it about 10 months ago. No problems so far.

I assume your post was in regards to the high driveshaft angle you get with the low pinion of the stock 9" 3rd member. I run a 4.5" spring under lift with a 1" body lift to accomidate my clocked flat t-case and flat skid plate. I have no vibration problems at any speeds. I usually run my Jeep on the highway at 70-75 MPH with frequent long road trips. I can get it up to 85 and still no driveline vibes. The only thing I have encountered is a bad u-joint after 7,000 miles. I run a CV in the rear and angled the 9" upward a few extra degrees before welding on the spring perches. I just serviced the 3rd member and everything was a-okay including the pinion bearing (which some people worry about starving).

I would go with the 9" but that's becuase I am a little bias. I am sure a Dana 44 would suite your needs just fine.
