Servo not working right

[TurboTeg512]

So I have a fazon 6s. The servo works fine in one direction only, then makes a horrible buzzing/grinding sound in the other direction. Does anyone know what would cause this??? Thanks.

stripped or binding gears maybe. You can take it out and open it up to see. Servos are pretty straightforward and if you're nervous about it just take a picture of the gears before you take them off so you can put them back on again right.

Arrma do a rebuild kit, but it might be time to replace it with a higher torque and faster servo. The most important thing with servos is to set your endpoints correctly and make sure your servo saver is working.

Disconnect the servo and turn your wheels by hand. Sometimes the ball joints will stick after getting dirty. I had this same problem recently and loosening the ball cup resolved it.
