Noisy Air compressor

When I bought my truck, the kid at the TA had to use a hammer to beat it off, it looked like the original from the factory. I recently replaced the entire air dryer, cheaper than fixing at this point. I installed a reman from FleetPride, under $200 with the cartridge. I had the kid at the TA install the air dryer as they have a pit. This was after installing a new air compressor in the driveway. Then the fun began... LOL!

After you did all that did the noise go away? I have had experience with several ISX Wabco compressors When making air they all knocked.
