Hey everyone, i've been lurking around this forum, and it's been great =]

I just finished building my Tb-02 tamiya, and noticed a problem with my first run. The wheels would spin, but there would be no torqe at at, and after reading some threads, i noticed my front and rear differentials were just loose...very loose. After tightening it up, it ran good for a few runs, but then it loosens up afterawhile. The problem is that after a million times of tightening it, the "Cap Screw" (the rod) became stripped..so now I can no long tighten "or even take out" the rod because it's stripped clean from my hex wrenches. Is there anything I can do guys? or would I have to buy a whole new diff. setup? which i would need the bearings, balls all together because i cant take mine apart because of the stripped cap screw..I hate this part =/ Thanks everyone!!

well i am new to the chassis any i like it it seems that the only bad thing about the chassis is the fact that the diffs will get loose or the screw eventually breaks my only advise for this would be to get new diffs or just lock them but it wont handle as good as it used to on the corners i used my for drifting and is as far the best chassis i owned for it.....

use a tiny bit of loctite on the screw so that the vibration doesn't loosen them.
