possible differential problem...

[mikey09120]

hey guys
i have an erbe and so far have only ran 12cell nimhs which belong to my friend. the gearing is 18/54. the rear differential has a "sticky" spot. when i spin the spur it gets slighty hard to spin for like an 8th of a rotation then it is free. i hear the noises coming from the rear diff. its not the center driveshafts. maybe a bent pinion tooth? it always happens one rotation of the half shafts any help appreciated.
thanx
