CASE Tractor AC evaporator replaced, Front loader tractor receiver dryer was not replaced. 

This Thing is so loud my ears were ringing when I shut off the engine.

Have to agree, replacing the drier REALLY REALLY does make a difference if you want the system to be trouble free.

With the supply chain issues of getting a replacement evaporator, that drier may be tough to get as well. If you HAD TO, you could place the drier in an oven with a slow flow of dry nitrogen to recharge the absorbent. But what's that worth in time and consumables?
