listen to "oldtimer"s advice below. been there, done it. i would add that you will want to check for "snags". by this, i mean you should leave the opener unhooked from the door- completely. with the door in the open position, push the door down by hand- from the top, just like the opener does (pulling it down changes the fore-aft position of the rollers travel in the track). you'll have to do this from a step ladder or similar. as the sections go around the curved radius of the track, check to make sure the edges of the sections do not contact the jamb. this is where a lot of problems occur. if the sections bump the jamb, it puts pressure on the opener. if it touches the jamb, adjust the track out away from the jamb. your weatherstrip should be the only thing that contacts the door sections.
also check to make sure that the track is spaced properly from the edge of the garage door. usually there is excess slop side to side, which will make the door move side to side as it's going down.
if you have extension springs, make sure they are the same length when extended. if not, this will make them pull unevenly, causing bind.
i've had a chamberlain 1/2 hp screw drive since 1993, and have had no troubles with it.
one thing with a screw drive. if you decide to lube the screw (i never have) do so sparingly, as most oils attract dust, and will cause additional friction when it gets cold. don't know where you are, but here in n. iowa, it gets cold, and oils get stiff enough without dirt involved.
sorry about the long post.
just my 2 cents worth.
