If you have not at attention to the belts via custom tensioner Pulley, I highly suggest you do so. slop in the drive train is a known issue.
I added new aluminium pulleys last night and still have the problem. When the car is raised it runs fine (forward and reverse) but reversing on the ground there is still clicking or grinding of some sort. I have a Zero S belt tensioner in the middle but still a lot of slop on the center belt. Its hard to work out where the grinding is coming from.
Sorry, but what do you mean by "differential binding for blown bearing"?
The Leopard setup is brand new but seems to have a mind of its own. Is it worth investing in a sensored brushless?

I had to go with +7mm offset wheels in order to keep the wheels from rubbing on the control arms. I also run 3 degrees negative camber on the front to help clear them as well. It doesn't seem to be an issue for the rears though.
The front wheels doesn't seem like its rubbing on the control arms but will double check. When the car is moving its quite difficult to work out where the grinding is coming from. To get the +7mm offset can I just use a wider Hex nut or does it have to +7mm offset wheels? Sorry for the noob questions.
