2006 Cummins Ball Joints?
 

Hey Guys,

I am putting new upper and lower ball joints in and didn't leave a mark when I took them out. Is there a specific angle the ball joints can go in or no? Also I have left the axle shaft out and its gets real cold at night with frost. Is this bad for the diff fluid, will it need all new fluids?

Cheers!

Fluids should be fine unless a lot of water runs into it, I just put my ball joints in as long as you aren't using offset ones then you should be fine
