. Now under any acceleration it snaps violently to the right and backing off then causes it to lunge to the left so hard it nearly always spins out. Driving along the main straight is like watching an ECG trace on a heart monitor. This must have happened to someone before, so how the hell do you cure it? Was thinking of going to MUCH MUCH thicker oil? I have a hi torque servo saver, alloy servo horn and a very beefy metal geared servo and the Tamiya alloy steering set so I know it's not a weakness in the steering area. Also running TRF mini shocks with blue front and yellow rear springs. Please help before I throw this chassis in the trash and go back to my TT01.
By what your describing, I've had that happen before when I had my spice diff. The cause was the main gear that attaches to the out drive had been stripped out underneath where the pin goes through the out drive. It was in enough to make the wheels spin the same with the car off the ground, but with any real load the car was pretty much one wheel drive. So it would pull one way badly under power, and dive the other under breaks.
I'm running a 3Racing oil diff with 300,000wt in both my M05s and have no issues with either.
