Does anyone know what axle assemblies the Xterra has? I was under my truck this morning and noticed factor stickers on the drive shafts that said Dana-Spicer. Does the Xterra have Dana Axles?

No, they use the Nissan corporate H233B (V6) or C200 (I4) in the rear, and the R200A in the front. The actual driveshafts are made by Dana Spicer though, and why not. They're pretty straight-forward, nothing unique about them, so no need to build 'em yourself when Dana produces a ton of 'em every day already.
