The casters on my 10-year-old suitcase had cracked apart and gone wobbly. Time to buy a new one? — wait.
Replace just the casters and you can revive the whole suitcase for about 1,300 yen (~$9).
This article walks through the entire DIY caster replacement using a set I bought from Amazon.

The Damaged Casters
The rubber casters on my 10-year-old suitcase had aged and cracked.
The bag no longer rolled smoothly.
Picking Compatible Replacement Casters
The first thing to nail down is finding casters that fit. Three things to verify before buying:
| Spec to verify | Detail |
|---|---|
| ① Wheel size | Wheel width matters (e.g., the 21 mm dimension in the diagram below) |
| ② Suitcase-side: caster mount width | Has to match the new caster’s axle length (e.g., the 35 mm dimension below) |
| ③ Mounting style | Bolted (just unscrew) or riveted (most cases — requires cutting the axle to remove) |
Search Amazon for “suitcase caster replacement universal” and you’ll find lots of multi-packs. The safest move: take one of the broken casters apart, measure, then buy.

Replacement Steps
Tools needed:
・Hacksaw (if your casters are riveted)
・Phillips screwdriver
Both available at the 100-yen / dollar store.
Step 1: The replacement casters I used
Bought a universal 4-pack of casters from Amazon (about 1,300 yen). Measured the originals to confirm fit before buying.
Step 2: Removing old (riveted) casters
This suitcase uses riveted (peened) axles, so I can’t just unscrew them. Cut the axle with a hacksaw to free the wheel. (Hacksaw available at the 100-yen store.)
1. Tape the wheel so it doesn’t spin
Tape the wheel in place to make cutting easier.
※ Lay something underneath — there will be metal shavings.
2. Cut the axle
Insert the hacksaw blade alongside the wheel and cut.
3. Pull out the axle
Once cut, slide the axle out.
How long does the hacksaw cut take?
→ About 5 minutes per caster. Wear work gloves.
Step 3: Installing the new casters
Pass the new axle through the new wheel and bolt it on.
For a normal job, that’s it.
Total time: 30–40 minutes.
One snag in my case: the included bolts had heads that were too wide for the suitcase’s mounting holes (the bolt face wouldn’t sit flush).
Fix: I swapped them for M5 × 12 mm pan-head machine screws (smaller heads), bought at the home improvement store.
The original bolts had thread-locker pre-applied. Since I swapped to plain bolts, I added a drop of threadlocker (or glue) to the threads myself.
Wrap-up
Suitcase caster replacement: 1,300 yen, 30–40 minutes — great cost-to-benefit DIY. Before you give up and buy a new bag, give it a shot.
