To eliminate fron driveline vibration issues I did Spyntec manual hubs on the stock Rubi D44. I had already had the stock housing sleeved & gussetted and installed Pro Steer ball joints, and angle corrected housings weren't readily available from Dynatrac at the time. Spyntecs are essentially CJ / F150 size spindles, bearings & hubs, with the spindles adapted to take the JK's ABS sensors. They use CJ Warn Premium 30 spline hubs and the CJ size outer stubs, which on my kit were chromoly Superior units. On a Rubi that means going down from the 1350 axle u-joints to the D30 size 297s. To make up the strength I switched to CMs and chromoly inners. I read somewhere that they now supply a Rubi-sized outer stub, not sure on that however. To make it all work I had to convert to 5x5.5" wheels, and replace the rear axle shafts. As you can see, it all adds up.
The big revelation is how much better the road manners are on a JK with the front axle not spinning all the time. The usual benefits of manual hubs accrue as well, better mileage, etc. All that being said, I don't recommend them due to cost. For what the conversion costs you can get a Pro Rock unimited housing from Dynatrac.
As for your thoughts, the big issue with the conversion using salvage parts is being able to get the front ABS sensors cooking. Older knuckles & hubs won't give you that capability. If you went to a 60 Currie offers a converted F350 unit bearing with manual capability. Dynatrac and Solid also have conversion kits with ABS capability.
