does anyone know it the stock rear diff outdrives( the plastic ones) will hold up to a 5.5t brushless i seem to break at least one those Delrin cup joints every weekend and i dont wanna spend 10.00 bucks all the time or can someone give me a solution so i dont keep breaking them.... also does anyone know if on the DJC shaft can it be replaced (the dogbone part) id hate to have to buy one if i happen to break just the shaft
