Default MBX5T Front and Rear drive shafts

This weekend i bent my 3rd drive shaft on my mugen truggy. its the second LF in 3 months. I have not collisions and no big crashes during my race. Has anyone else had this problem and if so what have you done to not have this happen again. It did not effect the handling( i was still able to get a win) but i am very curious as to what going on. Mugen said its normal for the type of tracks in Nor Cal but i have not heard of other brands having this issue. If anyone has any input i would like to hear it. Thank you.

make sure your pivot balls are not screwed into the arms too far in the front. that could cause the axle pins to jam into the drive cups and bend them. no, i haven't had this problem. just make sure your drive cups don't have too much wear, that causes broken shafts when the suspension goes through the full range of motion on power.....

I beleive also the plastic bushings for the arms can cause this. They get loose and flex under stress. I prefer the brass bushing inserts and aluminum upper H/L mounts. Keeps the suspension more in check without any play or flexing during use.
