Agree 100%. Remove the IF pack, remove the cover, (soldered in 2 places to the foil on the board), and resolder EVERY connection in the pack. I usually see that the bad connections are at the tiny peaking coils (white, with 4 or 5 pins)

Just to mention: If the symptom is that the tuning is drifting, that's the IF pack. If it's snowy or popping off to a blank snow screen, then the tuner has bad connections.
