    Loud Knocking Noise

    OK, I am stumped. Last night my Mini Revo started to make a loud knocking noise when I accelerate. Sounded like the rear diff, but I tore it down and did not see any missing teeth. Next, I tore into the pinion. spur and transmission. Everything looked normal. All I have left is the fron diff to tear down. Anywhere else to look????

    shim your diffs when you put 'em back together and is there a stone stuck under the center skid ? may sound a little too simple but it's happened to me several times until i sealed the ends of the center skid with foam.
