How to Replace Step2 Hardware, Ball Shute & Flippers (143773)

Quick answer

Replacing the ball shute and flippers on a Step2 play set is a straightforward hardware swap: confirm the exact part number for your model, remove the old fasteners, fit the new shute or flipper, and tighten everything evenly. The most common mistake is ordering a part that looks similar but is not listed for your model, so always verify the number first. If you are unsure which hardware your set uses, a genuine Step2 hardware pack is the safest starting point.

A ball shute or flipper that cracks, sticks, or falls off does not mean the whole play set is finished. These are wear parts, and on most Step2 sets they are held on with ordinary hardware that you can remove and replace at home with a screwdriver or a small socket set.

The trick is knowing which part you actually need. Step2 uses similar-looking shutes, flippers, and fasteners across many models, and the model number matters more than the photo. This guide walks through the replacement in order, with the checkpoints that keep you from ordering the wrong piece or overtightening the new one.

What you need before you start

Gather the model number from the play set itself, usually molded into a panel or printed on a label, and compare it against the part listing before you buy anything. Step2 replacement parts are model-specific, so a flipper that fits one climber may not fit another even if it looks identical in a photo.

For tools, a Phillips screwdriver, a small adjustable wrench or socket set, and a container for loose screws will cover most jobs. If the play set has been outside for a few seasons, add a little penetrating oil for fasteners that have rusted in place. Work on a flat surface in good light, and keep children away from the area until every fastener is tight.

• Photograph the assembled part before disassembly so you have a reference for reassembly.
• Keep left and right flippers separate if your set uses a mirrored pair.

Step 1: Confirm the part number and fit

Look up the exact replacement for your model before removing anything. Step2 lists parts by number, and the number is the only reliable way to confirm fit. If your model's shute or flipper is not listed, do not substitute a similar-looking part from another set; contact the manufacturer or retailer with your model number instead.

This is also the moment to check whether you need hardware as well as the plastic part. Old screws, cap nuts, and washers are often rusted or stripped by the time a shute fails, and reusing them can leave the new part loose. A genuine Step2 hardware pack is a practical way to replace worn fasteners in one order.

• Checkpoint: write the model number and the part number on the same note before ordering.

Step 2: Remove the old shute or flipper

Support the shute or flipper with one hand while you loosen the fasteners with the other, so the part does not drop or twist the surrounding panel. Work around the part in a pattern rather than removing one screw completely at the start; this keeps the plastic from binding.

If a screw will not budge, apply penetrating oil and wait a few minutes rather than forcing it. Stripping a screw head turns a ten-minute job into a drilling job. Once the fasteners are out, set them aside in your container and lift the old part away cleanly.

• Common mistake: prying the plastic part off before all fasteners are removed, which cracks the mounting tabs.

Step 3: Inspect the mounting points

With the old part off, look at the holes and tabs on the play set. Cracked plastic around a mounting hole will not hold a new part securely, no matter how tight you make the screw. If the damage is minor, a slightly larger washer can spread the load; if a tab is broken, the panel itself may need replacing.

Clean any dirt, spider webs, or grass clippings out of the mounting area. Debris between the new part and the panel can stop the shute from seating flat, which makes the ball track bind. A quick wipe with a damp cloth is usually enough.

• Checkpoint: the new part should sit flush against the panel with no gap before you install any fasteners.

Step 4: Install the replacement and tighten evenly

Set the new shute or flipper in place, start every fastener by hand, and only then tighten them. Tighten in a cross pattern, a little at a time, until the part is snug. Plastic does not need to be crushed into place; snug plus flush is the goal.

If you are replacing flippers, check that they move freely through their full range before you finish. A flipper that binds usually means a fastener is overtightened or a washer is missing. Test the ball shute by rolling a ball through it; the ball should travel without catching on a lip or seam.

• Common mistake: using a power driver at full torque, which strips plastic mounting holes.

Step 5: Test, then check again after a week

Run the play feature several times and watch for flexing or rattling. A part that shifts under load will loosen its fasteners over time, so catch it now rather than after it falls off. Check that no screw tips protrude where a child could scrape against them.

Re-check the fasteners after about a week of use. New plastic and hardware settle slightly, and a quick snug-up at that point prevents most future looseness. After that, add the shute and flippers to your seasonal play set check along with swings and slide hardware.

• Checkpoint: no movement, no sharp edges, and a ball that rolls cleanly end to end.

Replacement steps at a glance

1. Verify the part number: Match your play set's model number to the listed shute or flipper number before ordering. Checkpoint: no model match, no order.
2. Remove old fasteners evenly: Support the part, loosen in a pattern, and use penetrating oil on rusted screws. Common mistake: prying before every fastener is out.
3. Inspect mounting points: Check for cracks and clean debris so the new part seats flush. Checkpoint: flush fit before tightening.
4. Install and tighten by hand: Start all fasteners by hand, then snug them in a cross pattern. Common mistake: overtorquing plastic with a power driver.
5. Test and re-check: Roll a ball through the shute, cycle the flippers, and snug fasteners again after a week. Next step: add this to your seasonal play set check.

Parts that commonly come up in this repair

• Hardware Pack (PI) 4451 (143992): This Hardware Pack (PI) 4451 (143992) is a genuine Step2 replacement part, designed to help you maintain or repair your Step2 product. It is intended for individual replacement parts orders and is available for admin ordering only. Part number: 143992. If your fasteners are rusted or stripped, replacing hardware at the same time as the shute or flipper avoids a second teardown later.
• Hardware & Wheel Cap Nut Pk (SU) (142565): This package includes the hardware and wheel cap nuts needed for select Step2 products. It is designed as a replacement part kit and is compatible with specific Step2 models (see original product for fit). Cap nuts cover exposed threads, which matters on parts children reach and grab, but fit is model-specific, so confirm your model before ordering.
• Component Pack Adventure Camper (143166): Component Pack Adventure Camper (143166) is a replacement component pack for a specific Step2 model. It shows why model numbers matter: a component pack is only useful for the set it was made for, and the same rule applies to shutes and flippers.

A failed ball shute or flipper is one of the easier Step2 repairs to handle yourself, provided you confirm the part number first and tighten the new hardware by hand. If your model's specific shute or flipper is not listed, stop and check with the manufacturer rather than guessing at a substitute.
