I was putting new axle housing seals in the Dana 44 7f and noticed the steering knuckles are not rotating smoothly. They feel like there are speed bumps or notches when move through full range of motion. I've never done this before, but I'm thinking the king pins/bushings should be replaced. The truck is showing 120k on the odometer.
If replacement is the way to go, any recommendations on parts or technique? Is it possible to lubricate these parts after installation?
Thanks in advance for your help.
