Are the center pilot bearing on the CV driveshaft the same? What years did they change?
79-85 and 86-up are different, I think I can check tomorrow if you like; I don't have a ujoint book here at home.(maybe I should..
) IIRC, 79-85 is a .413" and the later is a .5?? CBAssy. I went through this about 8-10 months ago. I had a hell of a time with the ball, so I called Marlin. I was referred to Jesse @ high angle driveline. I told him what was up, he said the best thing I could do was NOT replace the ball. I also had a Precision kit. I was told that their ball kits are junk.
I am not saying their ujoints are bad, that is what I run, and I have no firsthand experience with a CB failure, this is just what Jesse told me.
