Posted earlier about vehicle not moving from stoplight, eventually moved with rough rumbling sounds from front end. Could have been CV joint, u-joint, front prop shaft. Vehicle towed home.
Today I jacked up the front end, one side only. Transmission neutral, separated prop shaft. Rotating tire with hand, rough noises seem to coming mostly from near drive flange area rather than pinion gear (used stethoscope to test). Going to disassemble further but any thoughts? Is the pinion bearing shot? Maybe it is the pinion gears?
