When i go down the road my car makes loud roring noise

wheel bearing

Losing the bearing in the blower motor maybe.

If its loud knock could have broke a rod is there oil in it and is it clean and changed often ?

sounds like a wheel bearing very common in these

check wheel bearings

This is due to a clogged oil pan filter and gunked up lifters. Remove oil pan and clean screen filter. Use and internal engine cleaning solution before your next few oil changes to clean valves and lifters.

sounds lick a bad u joint at t case.

The first problem sounds like a engine mount has broken. the loud click sound seems like it may be some sort of bearing going or injectors knocking or valves knocking

Try jacking your vehicle up and turning the tires. listen for any odd noise like a grinding sound, wheels hubs have been known to make a grinding noise when they go bad.

It would, in the differential on each side, where the axles come in. Does the roaring noise get louder with road speed, and does it seem to come from one side more than the other? If so, it's probably a wheel bearing. Carrier bearings are possible also, but road-speed-dependent noises like that more often turn out to be wheel bearings than carrier bearings.
