My front axle is labeled 44-5f from what I gather that is a Dana 44. I wanted to replace my brake rotates they are rusty not grooved or necessary bad. Since it’s one piece with the outer hub I can’t seem to find the correct rotors. Also now that I’m in this far I’d like to change my axle u joints. And the dust seal that goes against that knuckle is shot.
My question is what is the best way to go about ordering the correct parts?
Thank you for everyone’s patience and assistance through this process
