Lube for squeaky axel shaft joints

[TITANIUM94010]

I'm looking for a lubricant for my TRX6 axel dog bone/CVD (I don't know which one it is) joints that squeak a lot. I'm using WD-40 silicone spray lubricant, which works, but doesn't last very long.

What lubricant should I use? I run in pretty dusty/dirt-y conditions most of the time, and I don't really want something that the dirt can stick on to.
I found something called WD40 PTFE spray, which forms a layer of really slippery material. I don't know if it's effective for squeaking though.

Any recommendations?

Thanks!

Pinewood derby dry graphite is the only thing i have used for years on everything but gears. It keeps things crazy smooth, polished and clean.

I have a small squeeze bottle of "Tri Flow" , which is a PTFE lube that I use on heim/spherical joints on my 1:1's, and it keeps the squeeks at bay for a long time. I run in dry/dusty conditions the majority of the time and haven't noticed it attracting dirt, at least, not enough to bother me. I'd give that WD40 PTFE a shot.

I use Fluid-Film. It is a great lanolin based general purpose lubricant/preservative available from any auto parts store.

I use silicone spray lube. That WD-40 PTFE stuff looks like it should work.

I use Purple Extreme on all the moving parts of my RC's except the bearings. When dry it doesn't attract dirt, can't really say if it will stop your squeak. A little pricey but I've been using the same bottle for about 3+ years now. I put it in a small applicator bottle to make it easier to handle.
