Anybody else have this problem?

[Highmark]

I finnaly fixxed my driveshaft problems and got the motor dialed in on the Mule the other day so I went to do some crawling. Got about three feet into the corse when I heard a 'POP' so I went to investigate. One of the plastic hexs had exploded, as in there was half a hex on the truck and a mutilated other half on the ground . So I replaced the platic ones with steel ones and tried it again, this time I bent a drive pin of all things, and striped all four stock stampede wheels.


Well I guess it's an exuse for another rebuild
