Most off-track jobs come down to realigning the track, replacing a bent section or worn roller, and re-tensioning the door against its springs so it travels straight again. On a door built to this area's typical 1970s dimensions, that's bolting the track plumb, checking the cable drums spin evenly on both sides, and running the door through a few full cycles before calling it done. Where it gets longer is when the track itself has been pulled off the framing - not uncommon on original installations approaching fifty years old - because that means re-anchoring into the stud or header, not just swapping hardware. We check the opener's force settings too, since a door riding crooked for even a short stretch can throw those off and send it back off track within weeks if that's ignored.
