why is this thread labeled Important? over half the thread topics here are about cars that don't even have ball diffs and it has much less views/replies than many of the other threads on the first 2 pages.

because a gear diff sticky would be of less use?

Because many people have issues with ball diffs because they don`t know how to correctly build and/or break in a ball diff .

Gear diffs are simple and a monkey couldn`t screw them up .

Don`t like it , don`t read the thread . Simple as that .

I found this thread very useful. If it was not were it is, I probably would not have found it. I thank the person that did all the work for us and also the mod for placing it where it belongs.

You will never please everyone and you will always have people voice negative comments.

For the most part, its the RTR's, lower end RC's, and Traxxas that do not come with a ball diff of offer one as an upgrade. Go to any RC forum site and you are gonna see a bunch of questions about ball diffs and shock building tips. Thats why nearly all rc forum sites have them posted as a sticky thread. To help the masses. Great thread fellas.

Default diff in backwards

Is it just me or didn't he put the diff in backwards. the screw that you tighten should be on the left (the opposite side as the slipper nut.)

Thanks for the excellent video and write-up!

Anyone know what's in "motor cleaner spray"? Is that specifically for RC model motors? I live in Germany (and I'm a noobie ) and haven't come across that stuff...

not sure but its good stuff... it doesnt harm plastic. a friend used standard motor or brake clean spray and it melted some of his plastic...

edit: here's a good discussion on the subject

A NON-RC Motor spray/cleaner?

First off, thank you very much for these videos. I had my first short course race last weekend and had problems with the diff in my SC10. Today I rebuilt it following the instructions in the videos but my diff feels very gritty. The only thing I can think of is that I reused the diff balls for the rebuild. Is it possible that they have gotten damaged and that is what's causing the grittiness? What else could it be? I don't think I tightened the diff too much but would that cause it to feel gritty?

That is a possibility...

The first thing I would do is make sure you have new hardware[such as the balls, rings, and washers]

Then try the process over again, it is possible that the balls have developed flat spots from previous adjustment...

Is it screeching, or making crunching, barking noises???

Screeching could be the slipper clutch needing to be tightened more[especially if you have a fast motor]

Crunching or barking is the diff slipping, you'll need to rebuild the diff and make sure it's not slipping in the break in procedure...

Finally, if none of this helps, try taking it to the local hobby shop and see if they can help...Problems with diff's can be hard to diagnose without the seeing the diff in person...

I should have mentioned that I used the Associated rebuild kit when I did this diff so all of the hardware is new. The diff seemed smooth until I started rotating the tires in opposite directions. Now if feels very gritty with some spots worse than others. You can almost feel it catching in some places.
