I can only point out the usuals - grind down center diff housing to straighten carb angle, grind down chassis guard to clear the servo, make sure the servo is off the chassis, use the rubber grommets, and make sure there is no flex in the servo tray on either way of operation.

Since then I haven't had any problems in both buggy and truggy using 7955 and even a 985 for almost a year.
