I have aquired a Meade ETX70 that the focuser is stuck really bad and i'm unable to get at it is there any one?

That is knowledgeable in dealing with how to fix the problem. There is a couple of sites that attempt to explain how to disemble the ETX 70 but mine does not seem to match up totally to there description.Any better site or first hand knowledge is appreciated and i have pulled and pulled but i'm unable to get the front half with the Lens to come off...
