Since the cold snap the door has been stiff and noisy first thing, and after the last thaw the bottom corner began to judder. There is slush in the foot of the track and a bloom of rust on the lowest wheel.
Roller replacement changes the small wheels that guide each section of your garage door along its track. A four-section residential door usually has ten of them: one at each end of the three hinge lines, one in each top fixture and one in each bottom bracket. Each is a wheel on a steel stem, commonly on ball bearings though some nylon rollers run bearingless, carrying a share of the door's weight more than a thousand times a year. When they wear, the door turns loud and rough. Fitting a matched set of new rollers, then checking the track and hinges they run in, brings back smooth and even travel.

Scene 1
A roller is only as good as the bracket that holds it. The technician inspects every hinge for cracks at the knuckle, elongated holes and loose or missing fasteners, checks that the top fixtures still adjust and hold their setting, and looks over the bottom brackets for rust, deformation and the condition of the cable attachment. Jamb brackets and the flag brackets at the top of the vertical track are checked for movement. A door moves more than a thousand times a year and that vibration loosens bolts, so a hinge that has been working loose is often the reason a wheel wore crooked, and it is refastened or replaced as part of the same visit.
Scene 2
Nothing is unbolted until the door cannot move. The technician disconnects the opener, positions the door where the work is safest for the rollers being changed, and locks it there with clamps or locking pliers set in the track under the wheels so the sections cannot slide or drop. With a heavy door left in the open position, the horizontal track and its hangers are checked for a firm hold first. This set-up takes a few minutes and is the reason the rest of the job can proceed calmly, one roller at a time, without a section shifting while a hinge is loose.
Scene 3
Rollers wear slowly, so it helps to know the early signals. A rhythmic clicking that travels with the door, like a train over rail joints, points to a bearing beginning to fail. A wheel that leans to one side in its hinge, or a door that starts to rock as it rounds the curve, suggests a stem or wheel wearing oval. Grinding that returns a day or two after lubrication means the wear is in the wheel, not the grease. Catching these while the door still runs makes the next roller change a planned visit rather than a door stuck halfway.

Lubricant restores bearings and hinges that are still sound; it has nothing to offer a wheel worn oval, a nylon tire that has cracked, or bearings whose balls have pitted their race. When a spray settles the noise for a day or two and it returns, the wear is in the roller itself and replacement is the answer. Spray on the track or a plastic wheel can make matters worse by collecting grit, so the technician cleans that off as part of the job.
By watching where and when the trouble happens and then checking the parts in that spot. Rollers are spun and wiggled to reveal rough bearings and worn wheels; hinges are checked for cracks, elongated holes and loose bolts; tracks are checked for plumb, dents and spacing. A shudder at the curve tends to be rollers, a pop as sections pivot tends to be a hinge, and a rub the full height of the door tends to be track. Often more than one is involved, and the visit covers them all.
One roller can be changed on its own, and sometimes that is the sensible stopgap after a wheel breaks. The better result comes from a full set, because the other wheels have done the same number of cycles and are close behind, and mixing new with old, or nylon with steel, leaves the door running unevenly and sounding different on each side. A matched set also lets the technician set every top fixture and check every hinge in one pass.
