Garage Door Track Repair or Replacement: getting ready

Halfway up, the door lurches and one roller rides onto the lip of the channel. Near the curve the track looks wider than the rest, and the door hesitates in the same place on the way down.

Worth answering before the call

Is there rust on the track or brackets near the floor? Is it a single or a double door, and roughly how tall? Does the door rub the frame or catch at the same spot every time?

Should the track be lubricated?

It depends on the door, and manufacturers disagree, which surprises many people. Some want the track kept clean and dry, since lubricant there can collect grit and let the wheels skid instead of roll, wearing the roller and the track edge; others specify lubricant at the track bend. The moving parts, roller bearings, hinge pins and springs, get their own lubricant either way, in the type the manual specifies, with a few cycles of the door to spread it.

My door came off its track last month. Is this the same service?

It is the follow-on. Putting a door back on its track deals with the rollers and gets the door running again; track repair deals with the reason it left. If the reset showed a spread channel, a bent section or loose brackets, those are corrected now so the rollers stay put. Where nothing on the track was at fault and the cause was a cable or an obstruction, the track is simply checked and confirmed.
