Not sure if other CFM owners manuals have information missing but the 2023 UF600 owners manual shows 8 grease fittings on the rear.  If you pull the rear wheels, you will find 4 more which I found out yesterday.  I had removed one wheel due to losing the dust cover and wanted to see if I could still ride without causing issues with the wheel bearing while awaiting the replacement.
Also found the 45deg grease fitting for the sway bar on driver side was facing out for easy access but I found out that it was not tight. Now that it is tight, it is pointed towards engine.  Are they all threaded the same or can I buy a couple to find one with the right orientation?

Where exactly are these grease fittings behind wheel ?
I found them on sway bar and a arms.

We have had to replace several of our grease fittings due to them not taking grease.  These 45 degree ones need to be replaced but I can't find any that will work.

As I remember I found that the 6mm threaded ones fit mine and you can get them in straight,45 and 90s on Amazon.
