Is your suitcase caster broken?! How to fix and prevent springs from popping out

Good morning! When we travel, it is our suitcases that support us, and the wheels that support the suitcases. And the wheels are supported by their springs. Springs allow the suitcase to move more smoothly and handle bumpy roads better.
But what should you do if a spring pops out of a suitcase's caster? Because the spring is responsible for the caster's shock absorption and automatic return to its original position, using the suitcase with the spring detached can cause the wheel to wobble, increasing the risk of breakage. We'll explain in detail what to do in this situation, dividing it into five areas. We'll also introduce preventative measures. We'll explain specific steps, precautions, and practical examples to make it easy to understand even without photos or illustrations. If you're interested, please read this article.

Check the situation: Accurately identify the cause and extent of damage

First, if the spring has popped out, identify the cause of the spring coming off. Knowing the cause will make it easier to find a solution. This is the "diagnosis step" for determining a repair plan.

Check the condition of the spring

Damage <br>You need to check that the spring is not broken or deformed.
→If it is only a slight bend, it can be fixed with pliers, but if it is broken due to metal fatigue, it will need to be replaced.
Dirt or foreign matter
If sand or dust has clogged the spring and it won't return, clean it with a brush or compressed air.

Caster structural analysis

Guessing the decomposition method
There are two main types of casters:
Plug-in type: A structure that clicks into place without screws (easy to come off).
Screw-mounted: Fixed with a Phillips or hex head screw (requires tools to remove).

Please note that if you need to remove the casters, you must check the type of screw. Also, some suitcases have locks on the casters, so in that case, it is recommended that you check the instruction manual or manufacturer's website for instructions on how to unlock them. Also, be careful not to turn the screws too forcefully.

Safety confirmation

If the metal part of the spring is sharp, it is recommended that you wear work gloves or thick gloves. If you are careless and get cut by the metal, first check the condition of the wound, and if there is bleeding, apply pressure with clean gauze or cloth to stop the bleeding. We recommend lightly rinsing the wound with running water and disinfecting it with an antiseptic solution (such as Isodine). If the wound is deep, painful, or if a foreign object has penetrated the wound, it may be best to see a doctor immediately.

Check the surrounding area for any scattered parts (small washers or parts may be lost). If there are any, collect them as well.

Putting the Spring Back in: Hands-on Repair Instructions with Tools

Check the condition of the spring and then it's time to repair. If the part is intact, you may be able to fix it yourself.

Tools to prepare

Radio pliers (precision pliers) : Ideal for gripping springs with a diameter of 1 to 2 mm.
Precision screwdriver set : Insert into the gap between the casters and secure using the principle of leverage.
Magnifying glass : Check the fine grooves and fixing position (you can also use the close-up mode on your smartphone).

Specific work procedures

Caster angle adjustment
Before starting, it is important to stabilize the suitcase. Avoid slopes or unstable surfaces. Place the suitcase upside down and secure it with the wheels facing straight ahead (you can place a towel on the floor to prevent it from slipping).
Spring compression
Use needle-nose pliers to gently crush the spring and align it with the original groove. → If the end of the spring is shaped like a U-hook, hook it onto the shaft.
Operation test after temporary fastening
Rotate the casters by hand to check if they move smoothly. If they get stuck, they may be out of position.

Examples of failures and countermeasures

Failure example	countermeasure

The caster was damaged by a tool.	Protect the surrounding area with masking tape before starting work

If you need to replace a part: How to obtain genuine parts and compatible parts

If the caster spring is severely damaged or deformed, you will need to purchase a new spring. In that case, please follow the steps below.

Get genuine parts

Direct manufacturer support
For example, some suitcase retailers sell caster kits on their official websites. If you know the model number of your suitcase, you can be sure to purchase the correct one.

Use of repair reception service
In addition to purchasing, some suitcase brands will even send you replacement parts free of charge. For example, New Trip will ship you a new suitcase free of charge if the spring in the caster springs out due to non-human factors.

How to choose compatible and generic parts

If you can't get your hands on genuine parts, it's not a bad idea to choose compatible or generic parts. Compatible or generic parts are generally cheaper than genuine parts, but I don't think there's much difference in quality.
How to measure size
First, you need to measure the diameter, length, and wire diameter of the spring with a vernier caliper (e.g., diameter 5mm x length 20mm).
Recommended places to buy
Know the size of the parts and where to buy them.
Amazon: We recommend searching for "suitcase spring casters."

Tips for replacement

When removing the old spring, pull it out slowly with pliers (excessive force can easily distort the shaft).
A light coat of silicone spray on the new spring will make installation easier.

Call the Experts: Your Guide to Professional Repair Services

As mentioned above, we have explained the steps and tools you need to fix the caster springs on your suitcase yourself. However, if you are unable to fix it yourself (e.g., the caster shaft is bent or the plastic parts are broken), you should seek professional help.

Check the manufacturer's warranty

Generally, free repairs are available within one year of purchase. We recommend checking the product details of the suitcase before purchasing or contacting the store's customer support staff.
Also, for overseas brands, you may need to request repairs through a Japanese distributor.

Repair Service Types

On the other hand, if it has been more than a year since you purchased it, the warranty from the seller has expired and you will have no choice but to seek professional repair service.
Bag repair specialty stores (e.g., Able, Repair Lab)
→Cost to replace the entire caster: several thousand yen per unit.
shoe repair shop
→There are stores that offer caster repair as a side business (you will need to call in advance to confirm).

Emergency Preparedness: Travel and On-the-Go Life Hacks

The above articles are all solutions for when you're not traveling. But what if the spring pops out while you're traveling or out and you can't replace it in time or find a repair shop? Here are some "makeshift" techniques for when you can't get the repair environment right.

Fixing moving parts

Zip ties
The rotating part of the caster can be tied down to prevent it from dragging.
→You may be able to rent cable ties from the luggage wrapping service at the airport or hotel.
Adhesive tape (packing tape)
→ The spring part can be rolled up to prevent it from scattering (however, this is less durable).

Load balance adjustment

If the unit has two casters, remove one completely before use.
→Since the load is concentrated on the caster on the opposite side, it is limited to moving the chair only over short distances.

Utilizing alternatives

We recommend renting a smart cart at the airport or sending your luggage via courier.
Asking your hotel concierge to recommend a repair technician is also a good option.

Preventative Measures: Maintenance to Extend Caster Life

Inspect once every three months : Check for loose screws and spring elasticity.
Avoid carrying too heavy luggage : Stick to the weight specified by the manufacturer (usually 20-30 kg).
Avoid riding on gravel roads : Impacts can cause the springs to deteriorate.

summary

The key to a spring popping out is to act quickly. If you drag the caster too hard, the entire wheel will break, resulting in expensive repairs. Depending on the situation, you can repair it yourself, purchase parts, or hire a professional to extend the life of your suitcase!
And if you choose a suitcase that is particular about the quality of the casters, you will be able to reduce your worries about the casters.
