Pinion preload and crown gear backlash are the hardest settings on any steer axle, and this 125-page Carraro 20.22 repair manual PDF (OEM ID CA357356) covers them in full, then takes in the rest of the front axle: wheel hubs, epicyclic reduction, steering cylinder, and both the ML and LS differentials. Most of the book is disassembly and assembly, one group at a time. The sensor group has its own wiring diagram, and the procedures end with toe-in, steering angle, and post-assembly testing. Troubleshooting charts match axle symptoms to likely causes, and the special tools pages show the false pinion and preload measurement tool your bench will need. Feed the differential at 20 bar and keep bevel gear set backlash between 0.15 and 0.20 mm. A pinion shimmed by feel comes back as a whine. The PDF is bookmarked and text-searchable, and once you buy it, it stays with this axle for as long as you run it.
