Learn when to replace stroller wheels and follow a simple step-by-step process to install a new rear wheel set, with checkpoints to avoid common mistakes.

Quick answer

Replace your rear wheel set when you notice deep flat spots, cracks, or a wheel that wobbles even after tightening. If you need new wheels, the Mockingbird Rear Wheel Set includes two rear wheels that fit all Mockingbird Strollers. Installation takes about 10 minutes and requires no special tools.

Signs your rear wheels need replacing

Rear wheels take the most weight and wear, so they often need replacing before the front wheels. Look for a flat spot that makes the stroller thump with each rotation, visible cracks in the tire or hub, or a wheel that continues to wobble after you check the axle. If the tread is worn smooth in the center, you will feel less grip on smooth floors or slight inclines. These are all signs that a rear wheel set replacement is due.

Tools and parts you will need

You do not need a toolbox for this job. The Mockingbird Rear Wheel Set comes with two complete rear wheels that install without tools. If you are also replacing front wheels, the Front Wheel Set is available separately and includes two front wheels. For this guide, focus on the rear wheels only.

How to replace stroller wheels: a step-by-step process

Follow these steps in order. Each step includes a checkpoint to help you avoid the most common mistakes.

Step-by-step: rear wheel set replacement

1. Park the stroller and lock the brake: Set the stroller on a flat, stable surface. Engage the brake so it cannot roll while you work. If your stroller has a reversible seat, remove it to reduce weight and give yourself more room. Checkpoint: The stroller should not move when you gently push it.
2. Remove the old rear wheel: Locate the release button or lever on the rear wheel hub. Press it while pulling the wheel straight off the axle. If it resists, do not force it; check that the brake is fully released and the button is fully depressed. Common mistake: Pulling at an angle can bend the axle. Keep the wheel aligned with the axle as you slide it off.
3. Inspect the axle and wheel mount: Wipe the axle with a dry cloth to remove dust or debris. Look for bends, deep scratches, or excessive play in the mount. A damaged axle will make even a new wheel wobble. Checkpoint: If the axle is bent or the mount feels loose, contact Mockingbird support before installing new wheels.
4. Install the new rear wheel: Slide the new wheel onto the axle until you hear or feel it click into place. Press the release button if needed to help it seat. Then pull gently on the wheel to confirm it is locked. Common mistake: Not pushing the wheel on far enough. It should sit flush against the mount with no gap.
5. Repeat on the other side: Follow the same steps for the second rear wheel. Replacing both rear wheels at the same time keeps the stroller level and prevents uneven wear. Checkpoint: Both wheels should spin freely and sit at the same height.
6. Test the stroller before use: Release the brake and push the stroller forward and backward on a flat surface. Listen for rubbing or clicking. Check that the wheels track straight and do not wobble. If you hear rubbing, remove the wheel and reinstall it, making sure it is fully seated.
