Your suitcase gets thrown onto belts, stacked under other bags, dragged over kerbs and squeezed into overhead bins. Most of the time it copes — until it doesn't. And the worst place to find out is halfway through a trip, with a wheel rolling away across the terminal floor.
Luggage rarely fails without warning. Here are five signs to watch for, what happens if you leave them, and what the repair involves.
1. Wheels that grind, wobble or drag
One of the most common problems we see, and one people often put off. Grinding, a wheel that wobbles, or a case that pulls to one side means the wheel is wearing out.
Why it happens: spinner wheels take a battering from kerbs, rough pavements and baggage systems. The tread wears, the bearing loosens or the housing cracks.
If you leave it: a bad wheel puts extra load on the other three, so a second one often follows. A wheel that snaps off completely can also damage its housing, turning a simple swap into a bigger repair.
The fix: a replacement wheel or wheel module. See our wheel repair guide for what you can check at home first.
Quick test: before each trip, push the case in a straight line on a flat floor. If it veers or makes a noise, get it looked at.
2. A telescopic handle that sticks, jams or rattles
The pull handle is one of the most mechanical parts of a case: nested tubes, locking stages, a spring release and mounts into the body.
What it looks like: the handle doesn't extend smoothly, sticks at some heights, needs force to pull up, won't lock, or wobbles when extended. Sometimes the button stops releasing it altogether.
If you leave it: a sticking handle tends to jam for good — either up, so the case won't fit an overhead bin, or down, so you can't pull it. A loose handle eventually breaks at its weakest point, often at the base mount, which makes the repair bigger.
The fix: depending on what's failed, a handle repair or a full handle replacement. Some brands use their own handle systems, which can take longer to get parts for.
Don't force a jammed handle. It's easy to crack the tubes or break the lock, turning a repair into a replacement.
3. Zip teeth splitting behind the slider
You zip the case shut and it opens again behind the slider, or the slider moves without closing the teeth.
Why it happens: the inside of the slider wears with use until it can't press the teeth together. Overpacking speeds this up by pulling the teeth apart.
If you leave it: a splitting zip usually gives way completely at the worst moment — often in the hold, when the case is being handled.
The fix: often just a new slider, which is a quick job. If the teeth or tape are damaged, the zip needs replacing and stitching in. Our zip repair guide covers how to get through a trip on a failing zip.
4. Hairline cracks in the shell
Hard shells absorb knocks, but each one leaves a mark. Over time, fine cracks can appear — usually at the corners, around the wheel housings and along the edge where the two halves meet.
What it looks like: thin lines you may feel before you see. On polycarbonate they can show as white stress marks; on ABS, small fractures near stress points. On aluminium, look for dents with small splits at the crease.
If you leave it: cracks grow. Each flight and each knock on the belt can extend it until the shell splits, leaving the frame and your belongings exposed.
The fix: crack repair reinforces and bonds the damaged area so the case is sound to travel with again. Small cracks are a much smaller job than a shell that has split. Dents on aluminium are a separate repair.
Check after every trip: the corners and the area around the wheels take the hardest hits.
5. A case that won't close evenly
If the two halves no longer line up, the lid sits higher on one side, or you have to press hard to get the zip or latches to meet, the frame may have been knocked out of line — or a hinge along the spine has loosened or broken.
If you leave it: a misaligned case strains the zip and latches every time you close it, and the stress can crack the shell near the hinge mounts. A broken hinge also lets the open lid flop back, which can snap the remaining hinge.
The fix: frame alignment brings the case back into line; loose or broken hinges can often be repaired at the same time. Frame work takes longer than most repairs, so don't leave it until the week you fly.
What these repairs cost
Every one of these is a routine job at our bench. Estimated starting prices and usual turnaround for each repair, in Singapore and Malaysia, are in our repair price guide, and the repair services page always has the latest figures.

Fix it before the trip, not during it
Each of these starts small: a slight wobble, a sticky handle, a crack you can barely see. It's tempting to hope it'll hold for one more trip. If you've got a flight coming up, bring the case in early — some repairs take a week or more.
