Granite Grease for granite differentials. Red and tacky vs Tamiya anti wear grease.

[Armarookie43]

Which one would you use? I already have the red and tacky in hand because of a previous project (a whole tube of it). Thoughts? Thanks.

For the ring and pinion? I don't recommend a really sticky lube, because that adds additional friction and resistance to turning because the gears are sticking to each other so much. This adds heat and resistance. I actually use Tamiya anti-wear as a limited slip grease to ADD friction to my open diffs.

A light white lithium or silicone grease is what I would suggest. I use Traxxas silicone grease personally.

From the 4 diffs I've examined, the stuff that's on the ring and pinion gears from ARRMA almost looks like Vaseline.

I'm still deciding on what to use on my rebuilt diff gears. I'll either use some of my tacky red synthetic grease, or the Chain Saver spray.

No NO LITHIUM GREASE it killed 3 whole diffs before i noticed that it was the grease was my issue

marine grease is the best all arround grease people recommand and use

Yeah, I'm not going to use any kind of "petroleum product" on the gears. I've had bad past experiences doing that with plastic gears that are heavily loaded, even using "EP" rated grease.

When your sun gear is worn after a week and can rock back and foward inside the diff

Was this an "Automotive" style white lithium grease?

This will happen really fast if you use lithium grease on those plastic diffs. Maybe on metal diffs its differant but oh boy they love to chew plastic diffs you bassicly run your diffs dry

I habe no idea it just says white lithium grease in the tube
3 weeks with marine grease and my diffs has no plastic residu near the gears and they look brand new

What's the brand name and/or part number?

I wasted pretty much 80$ on diffs don't make the mistake i did

I use silicone based brake grease for automotive applications. Has worked for me for over a year now. Diffs are the last thing original in my rigs. Have yet to need a single diff part.

I'm already using red and tacky between my ring gear and my pinoin on my Outcast. I was thinking about using it inside the diff on my granite. And on the outside too.

So use the red and tacky inside my diffs on my Arrma then? What are you using now? I have a whole bunch of the red and tacky from the previous project.

Im using marine And i love it 5$ for a tube is amazing exactly what you want doesn't cause much resistance when you sping your diff manually
