Slash 4x4 Is Having Noise Issues

I have been trying to solve this grinding noise for a long time.  When the motor blew it's bearing, I figured that was the source of the noise.  However, when I finally got the motor repaired, the damned noise remained!!!

Well, I looked and looked, and I found the source.  The damned driveshaft is bent, or something directly connected to it. 

The problem started when I had to remove the driveshaft cover, in order to re-gear the Slash ( to cool it down ) , and so the driveshaft must have gotten a rock in it or something.  I am really pissed off!!!  There are three engineering flaws that caused this:

First flaw, the motor won't mesh smaller gears, without removing the driveshaft cover.

Second flaw, the driveshaft cover blocks the motor from meshing properly.

Third flaw, the motor overheats, from the factory, if you don't re-gear it.

Wait, thats only two flaws?  WRONG!!!  The driveshaft cover is designed wrong, and the motor mount is designed wrong.  They both create the same issue, but those are two seperate parts, each with their own flaw!

Well, someday I will graduate from MS&T, and then maybe I'll be able to fix this crap, and make it run the way its supposed to!
