The loud noise comes from the wheels of my Buick Lucerne

If it is one of your tired bearings, it will tend to make a thumping noise that intensifies when it is under stress (spins faster and faster). So consider to examine by driving “fast” (neutral gear on and window open to hear only the noise of the wheels) that the noise is located here, if this is the case change it or them quickly. If it is a deformed tire, remember to visually check the entire tread area for linearity. If it is the balancing of the wheels of your Buick Lucerne that is the matter, you will tend to feel a vibration in the direction of the automobile as you go faster.

The loud noise comes from the engine of my Buick Lucerne

If the loud noise on your Buick Lucerne is related to air intake, the control will be done mainly visually, check all your air intake hoses by a visual control in your engine block to be sure that it is not damaged or disconnected which would cause an air intake, if it is just disconnected you can reconnect the air intake tubes yourself. Then examine that the engine idle speed is not random. In case you confirm one of these two trouble, take your automobile to your garage .

To validate this, get help from someone who will stand under the automobile while you accelerate to find the exact area of starting point of this noise.
