I've got a center sprint mounted automatic garage door where somehow the guide/pull wires came off the pulley. I've messed around with a couple of hours and re-wrapping the wire on the pulleys, trying to make them equal lengths seems to have no effect I can't seem to balance them out. The door starts down just fine but inevitably one side is lower than the other an the lower side starts to rub the rail.

What is the technique to aligning this?

Hi,
Is the pulley positioned on the shaft at same spot? Is the cable
gauge identical? What about the tension on the cable with door down,
identical? I use spring weight scale to measure them.
Good luck, and have fun.
