Maybe when you knocked that choke loose, it actually broke the thin wire that goes from the coil to the PCB, and the only thing making it look like it isn't broken, might be the wire insulation around the copper? Or if not to that extreme, the wire may well be weakened, or more importantly, a cold solder joint, which can appear fine at first glance, but completely hose an electrical connection.
I spent time back in the Eighties working in a little computer shop, where I did repair on old C64 and Atari products, and 9 times out of 10 when drives came in, it was a cold solder joint on the board, or a specific component that was prone to failure on some models.
If you had a handy can of freeze, a scope, a power supply, and a bit of know-how, you could test this whole theory, but all in all, it may be easier just to get that XO repaired. Remember, the crossover being run near the signal path wiring is one of easiest and most assured ways to induce noise in a system.
