what diff lube to use
 

i bought rc nova diff housings and 3mm 7075 cups to upgrade my emaxx. i haven't taken it apart yet to see what actually broke, but when i rebuild the diffs what lube should i use? silicone based? how bout some white lithium grease i have kickin around in the garage?

No silicone based, it will leak out and sit in your bearings, making them bind..

I use silicium grease in mine.
