Question Answered: 

Wow interesting diagnosis! The knuckle wouldn't cause that. It doesn't really have anything to do with suspension and thumping and bumping. I would say from your description it sounds more like a shock that needs replacing or a coil spring (more like the rear shock/strut). This seems like a suspension issue not a knuckle. Only possibility from their diagnosis, is the bearing is totally destroyed and even then it is not the knuckle that needs replaced. Perhaps a mount broke off the knuckle? Take it to a local shop not the dealer and see what they have to say.

Where is the approx. location of the noise? It could just be a loose weld on the catalytic converter heat shield or another heat shield has worked a little loose. May not be an issue you really have to repair immediately. Try to locate origin approx. of rattling noise and repost.

Couple of possibilities. Main one is water pump failure. They don't have to leak to be bad when the bearing goes they don't pump thus the coolant doesn't circulate causing an overheat. Another possibility is a blockage in the system usually caused by a plugged heater core. If the heater isn't pumping out heat, then the core is plugged and needs backflushed or replaced. I would look into the water pump first. Lastly, does the cooling fan turn on? A bad fan motor won't cool the radiator and cause overheat. If engine cools somewhat when driving but, overheats quickly while idling the fan may not be activating. Check that the fan is running when engine is hot.

Only thing I can suggest with this info. is try to reset the inertia switch (fuel cutoff switch). Located inside cab on passenger side against the firewall. Pull back carpet or plastic and you will see the switch. Hold in for 3 to 5 seconds and release and you are done.
