RE: 2WD Warhead
Mekong,
I myself being a Warhead owner, I have found it absolutely necessary to always look for the front drive shaft after the bulkhead decides to let loose. I have made this mistake twice picking up the truck and heading home just to leave the drive shaft in the vincinity of the crash.
Truck should run fine without the front shaft for the time being. Just have to do some tweaking on the suspension to get the traction you want.
