I'm a big fan of the redline cv2 grease which is calcium based, OEM grease is lithium as u guys might have expected. What's the best way to go from lithium to calcium in the u joints? I was just going to pump the red line stuff until the grease came out clean from all 4 ends of the u joints. I was going to do this 2-3 times in a week with some driving in-between to make sure whatever that is left of the old stuff gets mixed with the new and flushed out. I'd think after a couple of flushed that all contamination would come out. Thoughts?
