Chassis grease...

[JMBT]

I use a green poly urea based grease, forumulated for marine applications. I use it because it is the only thing I have found that doesn’t seem to wash out in wet conditions. One time last year I ran FL to NM and was in the rain the entire time, no shi#t, the whole time. When I got under to grease after delivery there was still grease showing on my slack adjusters. I am not saying it’s the best thing ever, but it works well for me.

I second what Rawze said, don’t mix red, (lithium grease) with green (poly urea) it’s bad news.
