Need Help!!
 

Hello How can I remove the shock shaft (threaded part) that was broken and got stucked inside the racers edge shock end. The shock shaft is for MBX5. thnx in advance.

Your only chance is a reverse drill bit; you chuck the bit into a drill, and drill into the broken screw (or in this case, shock shaft) and when it catches, it threads it right out. You can buy them at hardware stores.

Or you can buy a new one, which will probably cost as much as the special bit.

where can I buy this drill bit. Is there a bit small enough to remove the broken shaft? If its price is the same as a new one i'll probably buy the drill bit since I might use it again in case I break something again. thnx

You can buy them at pretty much any hardware store..I think they're around $10 or $15, and they're pretty useful for getting broken screws out of plastic parts.
