Doesn’t move. Just chatters. Gear mesh is on. Spur gear nut tight. Teeth on spur okay. Took diff apart & all gears okay. Gear lube though was all dried up. Any thoughts. Trying to help the G-son

Lucas Red n Tacky is what I use for diffs.Diff gears are okay. The lube is all dried up. What kind of lube can we use
The white lithium grease ??**WARNING** Don’t use a petroleum based grease, it will eat at the plastic and degrade it. Use a lithium based grease.

Anything that is lithium based and tacky to stay on the gears, white lithium isn’t tacky.The white lithium grease ??
White lithium ??
Traxxas uses a lithium or white lithium, and years ago the forum reccommended it"Lithium-based lubricants are used in cars and machinery in general. It's not advisable to use them on plastic parts. As lithium is based on petroleum, it tends to speed up rubber and plastic components decay."
That being said Mobil 1 uses lithium as a thickener and I've been using it for over a decade in my diffs and transmissions. I havent had any issues with it so far.
how to tell if slipper clutch bad ?? Okay, w/o tires you can barely hold both shafts at once. Shafts turn, spur turns but won't turn tires. With tires on just sits & chatters. Pulled diff apart - main shaft gear is good, pin holding main shaft good, 4 gears good. The diff lube was all dried up. cleaned it out but didn't add any lube. Still sits & chatters. Slipper clutch pads-2 are chipped but not worn down. Spur teeth also are good. wtf !!!!!There are multiple failure points within every RC. Since you seem to have checked the obvious ones - pinion, spur, diff, it may be something like the pin on a dogbone axle has broken, or if it has driveshafts, the splines in one of the driveshafts could be worn down.
But back to the diff, did you actually pull the diff case apart and inspect the gears inside? Just opening the diff housing and inspecting the ring and bevel pinion in there isn't all that can be wrong. The diff will come apart (most RC's) and inside is a set of spider gears that can get damaged.
Also, I just looked through the manual. It looks like it has a slipper clutch. When those go bad, you need to rebuild them and reset them.

That's pretty much it lolIf all the gears inside the transmission and the diff are good, Slipper is good, all bearings in the transmission, diff, and wheel hubs are good, Driveshafts are good, Spur gear is good, and Pinion is good, then Id start looking at the motor.
