Hello there. When you do remove the axel, immediately lace each joint with
2 zip ties. This, before you even wipe your brow.Only someone who has done
this before can appreciate how easily the balls fall out.If one ball falls
out, the others will think it is ok to come out too, and they will. What a
mess you will have on your hands then. Alternatively, you may want to
completely dissamble the axel for cleaning,but be prepared for the
reassembelly

I have read postings where rebuilt axels are many times not rebuilt
correctly. I think this is because the balls are not installed right.
Complete, unobstructed circular motion is only obtained if the balls are
installed correctly.These postings complain of obstructed motion.My rebuilt
axels came in the mail just fine.It was after recieveing them that the
balls did fallout and I learned how to put them back in.Cant explain better
than Bentley does, but you will need to just do it yourself to learn the
difference. You will know when the balls are in correctly.

Use the ties when you enter the black hole with your buttered up axel.
