These parts are no longer available from Isuzu. Driver's side steering knuckle (part 2B in the diagram). Also includes the steering arm (parts 59 and 36 in the diagram). The condition is very good. Race surfaces are excellent, threads are good, includes spindle nut. The factory part number for this item is: 8944550810. Refer to table below for model years that it will fit. It is best if you check your VIN with the dealer to obtain fitment. Item is greasy, as removed from vehicle.

Donor vehicle VIN: J8DC4B1K8V7006980

I also have hubs for this vehicle. They are part number 8944752854. These are correct for NPR diesel, but not for gas in most cases.

Here is list of models and years that I found on the internet. Refer to it at your own risk:
