You have to remove the washer from the top screw on the inside servo post, otherwise it rubs. Some servos you may also have to file a very small amount off.
As simon says the front input shaft is only aluminum and can get a slight bend in a big crash.
Its also possible, but less likely, for the main centre propshaft to get bent.
If you have installed new gearbox and bulkhead parts check that the gear box top is screwed down nice and tight otherwise the input shaft can wag. Sometimes with the cross-head screws its difficult to judge when the screws really bite.
