Not so free drivetrain.
After running with a oneway fitted since i built the car i need to use a ball diff up front due to track conditions but found the drivetrain would not spin freely like before. Thinking i must have a damaged gear some place i replaced the lot with new items but still no better. The drivetrain seems to bind slightly ever second or so turn without the pinion fitted and my lap times are being effected as a result.
Any ideas ??
