Tongiht at racing my speedo kept going slow i thought what! this aint right by the ooks of it my speedo had thermalled for soem reason it came off hot i couldnt find out why my gearing was the same no crap in drive chain its all free then in last round it just went dddddrrrr like the pinion came loose or i had stripped the spur but it wasnt . So i held the spur and did the turn the diff and the other wheel just turned in the same direction no diff action! So took it apart just assumed it just needed a rebuild or soemthing so i took it out blasted all the balls down and old grease out rebuilt with losi diff lub the cream stuff and still no diff action i turn the oen out drive and th eohter doesnt turn at all no missing diff bals or anything :




can anyone help.
