It looks like the parts totaled around $1900, not including labor
This accounted for *everything*......the locker unit, gears, bearings, all gaskets/seals, gear oil, cables for the OX Locker actuators, etc....
Your part costs would obviously be cheaper if you're not re-gearing.
This part total was for a pretty thorough rebuild of the rear axle. All bearings and seals were replaced throughout, and the rear was also re-geared to 4:10
using Dana Spicer OEM gears -- and there may have been slightly less-expensive gears available from a different vendor. These were around $400 or so for the set alone, so if your gearing is already where you want it, you're that much ahead of the game.
If you're curious, here's the complete part list.
