I am inquiring to find out to those who own a cen genesis what they feel is the weak link of the truck. I am liking the truck but first broke an upper a arm on the front, ordered alum. ones turn around and was backing up and hit my playset in backyard and broke the knuckle hub. I am not bashing the genesis but getting ready to order this new part and since generally you have to order parts I want to order spar parts if I need to. Thanks.
