I'm not disagreeing with you, I just want to better understand your point. Perhaps I am missing something?

Your shock shafts should be about 3.175mm in diameter. You need new shafts. The dirt build up on your seals will/has worn away at the shafts, that might be the reason they're smaller now. What are you using to measure the shafts? Are you sure it's accurate? HTH.

Gear diff send the power to one or the other wheel if one wheel is in the air or has less traction....
just like your real car...

ball diff sends the power more even to both wheels, that why they have better forward bite on the bumps...

But why the left wheel? I understand how a gear diff works sending more power the wheel with the least traction, but I figured it would be either left or right, not specifically the left.

Believe it is to due to the gyro force from the rear wheels spinning...

spin the wheels in reverse and it would be the right wheel

It has to due with the gravitational pull from the poles..... north of the equator you left wheel would spin but south of the equator it would be your right wheel.....

...and if you lived right on the equator, your junk would be perfectly hooked up every day

it goes either way, not favored to the left. the same thing happens with a ball diff but not as much.

Well, there is no such things as the perfect ratio to fit all situations. Take what that site gives you and go from there. You may need to go up or down a few teeth depending on the particular car, track conditions, size of track, etc.

ball or gear diff the wheel with the less traction or the the that is in the air is going to spin. In a gear diff it's way more ajustable. Because you have diff oil. The thicker the oil the less the tire will spin when that tire has less traction. The thinner the oil the more you one tire will spin when that tire has no traction. I don't why you think gear diffs or for bashing but that's not true. 8 scales have gear diffs and same with the SC trucks.

This is why.. The SC trucks have them for ease of maintnance bc they are aimed at a beginning class. Less maintnance and more durable, but as they are trying to explain the ball diffs put the power down better.

Eight scale buggys have gear diff for durabilitly reasons and not from a performance stand point. There is no way you could get a ball diff to survive the punishment that a eight scale buggy puts out. It's hard enough to make one survive in a tenth scale nitro truck.

The reason they are probably considered bashing item is because they are low maintenance

they are low mantinence but they are easier to use than the ball diff. i can never get mine to work good. gear diff = easy, adjustable, and simple. Ball diff = hard, untunable, and a pain in the ass. thats just me
