Does anyone have any ideas on how I can get my rig back on the road? I figured out the crazy vibration was caused by a failed harmonic balancer and pulled it off for replacement. Problem is, the key that keeps it from spinning is halfway sheered off as well. There is limited space obviously, does anyone know how I could remove the remnants of what's left wo removing the whole front end of the jeep? It's an AMC 360 from a wagoner. Any assistance is greatly appreciated!
