the other day i was running my savage around and i noticed the rear wheels werent pulling much. well i though maybe something was wrong with a diff or whatever. i sat down and took apart the rear end, nothing wrong. i got to looking and the hex drive was really loose inside. i looked closer and i could spin the hex head by hand. the wheels were on tight so that wasn't the problem. was it just a fluke, or is this a common problem with stock wheels? i have the BB 21 still in it but with some minor porting i dont think it made that much of a difference. what sucks is i just droped my extra cash on other stuff so i have to wait a week to get some new wheels
