Inspection

Classic Symptoms:

Remove the Propeller Shaft from the diff (you can leave it in the transmission to prevent transmission fluid from leaking). Flex the u-joints by hand. It should:

• Move smoothly (not stiff)
• Be tight

Replace if loose or binding.

Replacement Procedure

Use a press.
