Lift Cables and Doors Pulling Out of Square in Tinley Park
Most people meet the lift cables on the day one of them lets go. Until then the springs take all the credit, which has it backwards. Springs cancel out the weight. The cables are the part that physically hauls the door up its rails.

There is one at each side, anchored low on the door and wound onto a grooved drum up on the shaft. They only work while both hold the same tension. Lose it on one side and the door begins pulling itself out of square in the opening.
Two routes to failure on the doubles fitted here
The abrupt route follows a spring break. On a sixteen-foot double of the sort fitted right across Tinley Park, a counterbalance letting go dumps the whole weight in an instant and slams both cables at once. Typically one comes off its drum, and by the time anyone gets out there the door is hanging by a corner.
The gradual route is imbalance. A door running slightly askew for months, often because a previous spring set was never matched to it, chafes its cable where it meets the drum until strands begin parting. There is usually a faint clicking on the way up long before there is anything to see.
Why the fixing at the foot of the door is off limits
The bracket the cable anchors to low on the door face carries the entire counterbalance load whenever the door is down. Unbolting that with tension still in the system is one of the ways this job puts people in hospital. Tension leaves the shaft first, every time, before a spanner goes anywhere near it.
Older doors around the village running the long extension-spring layout have a second cable threaded through the middle of each spring, there purely to catch one that breaks. It disappears during budget repairs far more often than it should, and it goes back in as part of the work.
Fitted in pairs, then proved across the opening
Cables go on two at a time, cut to matching lengths. Putting a fresh one alongside a stretched survivor lands you back here inside the year, so it is not offered as an economy.
Drums are then examined for wear and raised edges, indexed back to matching positions, and both sides then brought to equal tension. The door runs several cycles while we watch whether it stays level, and the job is signed off on a manual balance check with the motor disconnected.

Questions
Tinley Park questions about this job
A cable has unwound off the drum but nothing appears broken. Can it simply be wound back?
Winding it back without establishing why it left means it leaves again. Cables come off because the door was out of square, because a spring failed, because the drum has worn a lip, or because the door was closed onto something. Deal with the reason first, then rewind and retension.
How long can a frayed cable be left?
Think of it as this week rather than this month. Once strands have gone, the remainder is carrying everything, and the end arrives without warning. Until then keep the door shut and stop parking under the opening.
One corner lifts an inch or two before the other. Cable or rails?
That lead almost always points at uneven cable tension, or at one side having slipped a groove on its drum. Rail faults tend to announce themselves as binding and noise rather than one corner setting off first. We look at both, since a door that has run skewed will usually have chewed its rollers too.
