[hypoxia]

I recently went through this on my coach too.  In addition to the documented zerks, I had (2) zerks on the front axle sway bar bushings.  The rear drive axle sway bar did not have the zerks, but did have (2) holes already tapped.  I went ahead and installed new fittings in the rear.

I used a silicone based grease for these rubber bushings as petroleum grease can cause the rubber to deteriorate.

And that's why this forum is so necessary.  I found exactly what you reported on the sway bar bushings.  Silicone grease is on order & I'll look through my zerk collection to add the two on the rear sway bar. I updated the Grease Zerk Locations document.

Thanks Rob!
