My garage door no longer closes smoothly. When I manually close the door,
the force needed varies from almost none to quite a hefty pull. When the
garage door opener closes the door, the whole thing bucks and shakes.
I've
lubricated the tracks, wheels and axels with no luck. The door is not
warped and the tracks are not bent or buckled. When the door is full
open,
the springs sag about the same amount, so I'm assuming that the tension is
about the same in both springs. It seems to hang up when the wheels are
on
either side of the bend in the track.

Any ideas?


Don,

I had the same problem. But upon further inspection one of the metal wheels
was jumping the track. Not every time, just some times.

I had to use my 24 oz framing hammer to set something right, but it was
somewhat destructive, unfortunately.

It's working fine now, but the best advise I can suggest is to keep the
track free, clear, and well lubricated.

Good luck.
