Pull the diff and put 10k or 15k associated diff oil in it. Put the diff back in and say hello to rear stability. I chased mine all over until I put 10k in it and it is still a little loose but I like it. I think 15k would be better for a newer driver. This will make the truck not diff out in corners and give more bite. The reason you are fish tailing is due to a little too much motor, and getting on the gas to fast causing the diff to diff out and spin one wheel causing a loss of control. The thicker diff oil will fix this by making it harder for the diff to diff out.

How does the ball diff compare to the gear diff with the heavier fluid in it?

Tires make a big difference especially for racing applications. On my SC10 I didnt used black grease in the diff. I ran 100k OFNA diff oil just on the gears and the handling was a night and day difference. Also shock setup will play a difference to in handling and steering of the truck. Sometime it just could be the track conditions were the track is drying out and loosening up.

Well a ball diff will be a better bet for traction but will require more maintaince so that is works correctly. But you find the setup in a gear diff that works then just run with it.

-softer rear tires
- suspension bias... try 60 wt oil front 40 wt rear it'll slow down the front end a bit and give you more stability
- weight in the rear,... adding weight behind the battery, in front of the transmission, even strapping some to the rear bumper assembly will help rear traction...
- if your esc/radio has expo you can dial some in to soften the initial punch as well so you don't spin out as much on initial trigger pull...

or just turn down epa to 90% or 80 till you get used to throttle control. The biggest upgrade in RC is wheel time. Just keep at it. You will get it.

+1. Spinning out when you mash the throttle isn't a car problem or a tire problem, it's a driver problem.

I might or may have jacked the thread, but I'm wondering...

What's the best method for getting at your Gear-Diff to work on it?
Do I need to remove all the parts around it prior to getting at it?

pretty much need to remove it... take the screws out from the bottom and detach the transmission case from the bottom, then remove the rear bumper bracing and the transmission case screws, it can then open up and gear diff should pop out to be serviced...

Lower the rear ride height a little so the dogbones are level or just below.
Increase in traction and stability!

Ya just be careful as to lower your rider height to low will effect the way it jumps and lands. And will also effect handling mid-corner. If anything the dogbones a tad below level. There are other things you can do to get stability.
