People say the wheel broke off because the Type 59(5 pairs of wheels) can't stand pretending to be a Type 96(6 pairs) anymore.
Anyway here's a close up of the damaged part.
Seems like the joint broke apart because of metal fatigue.
Not sure if it's related to quality control or the high stress environment.
Age is not a factor here because these tanks are almost brand new.
To answer the age-old question of "can tanks provide indirect fire like a howitzer?". Yes, the answer is yes. Here's a ZTZ-96A belonging to the 13th Group Army conducting indirect firing at a target 9km away.
