Differential question

[Garymoe1963]

When my truck is sitting there running and I rev it up it does not go anywhere. How do I lock up the differential? And where?

I don't think the diff is your issue. You're not getting power from the engine to the drivetrain. I would start by making sure the clutch is actually engaging, then just go down the line from there. Check your gears, as well. Make sure they turn without binding.

Check the screws on the drive gear in the center of the truck. The gear you can c from the bottom of the truck.

They Co email out and keep the truck from moving.
