there was no wheel hop and this was not on a launch. this was shifting into second gear. but when i got into second i hit high boost and got on it hard and with the old diff the car just spun the tires so there was no real stress on the axles but this time it just hooked hard and it just snapped the joint. the car does make a tad over 500whp so i will need to look into better axles but i dont have a 1000 dollars. so let me know if anyone has any options. thanks
