A fella once told me that God looks out for children and Hot Rodders...
Perhaps getting back under there and using a torque wrench would be time well spent?
The fellas that bolt up flanges where I work use impact wrenches... they are miserable when it comes to repeatable accurate torque application because they rely on air pressure and how long you hammer the fastener.
For critical fasteners always use a torque wrench. It's advice I need to follow too.
