Ideally, the operation of a gear diff is a fluid situation. Read on to learn how diff fluid affects how 4WD cars apply power the ground.
We all know that that we have to tune our diffs, but why would you want to change the height? This quick overview explains how it impacts your car's handling.
Know the diff between your diffs - learn about 3 gear, 4 gear, ball diffs, and limited-slip diffs here.
How to fix understeer (push), oversteer (loose), and other common handling problems for both on-road and off-road RC cars.
Ty walks us through how he builds ball diffs to get the best life from the diff and the most traction.
Tony Newland of Klinik RC shows in detail how to build (or rebuild) a ball diff the right way. This one goes almost 25 minutes, so grab some popcorn and get ready for some serious learnin'.
Learn the secrets of building a smooth, leak-proof differential from a pro.
Learn about the oils, greases, and prep needed to get a gear diff running super smooth in your 1/8th scale ride. He uses an XRAY diff to demonstrate, but most of the techniques and advice are universal.
He walks you through his methods, how he approaches shimming, which greases to use, and how he marks the diff case. He demonstrates on the MBX8's diff, but most tips will apply to any 1/8th gear diffs.
Klinik RC walks us through how they build the "perfect" gear diff, that is, one that doesn't leak diff oil!
