How to Select a Trailer Hitch
Knowing your hitch class and receiver size comes first — anti-rattle kits are sized to one and one quarter inch or two inch tubes.

An empty hitch receiver that clanks over every expansion joint is one of the most common shop complaints we hear in Canada. The tube is steel. The pin has a little play. A ball mount or bike rack that sits slightly loose turns that play into a sharp rattle. This page is practical: why empty receivers chatter, when a tighter pin helps versus a real anti-rattle kit, when a cover only helps cosmetics, and which live CURT SKUs we stock for the job.

Trailer Hitch Installation Techniques
A clean install with the right pin and torque habits removes some chatter before you buy extra hardware.

A ball mount that fits the tube properly still needs a solid pin story. Play at the shank is what anti-rattle kits address.
Watch on YouTube →Why an empty receiver rattles
A receiver tube is built with clearance so a ball mount shank can slide in and out in a parking lot, not in a machine-tool press fit. That clearance is normal. On a washboard gravel road or a frozen Ontario expansion joint, the shank or an empty pin bangs the tube wall and you hear it in the cabin.
Empty tubes rattle too. A loose hitch pin, a missing clip, or a cover that does not actually wedge the tube can turn the receiver into a steel drum. The fix is almost never a new hitch. It is usually a better pin story, an anti-rattle clamp or kit, or accepting that a cover is about weather and looks more than silence.
Tighter pins versus anti-rattle devices
| Approach | What it actually does |
|---|---|
| Standard hitch pin and clip | Keeps the shank from walking out. A snug five-eighths or one-half inch pin reduces some slap, but it is not a quieting system by itself. |
| Anti-rattle hitch pin and shim | Takes up play at the pin hole with a shim-style quieting pin. Good first step when the mount is otherwise correct. |
| Anti-rattle clamp | Clamps the shank to the receiver tube so the mount cannot bounce in the clearance. Often the strongest noise cut for a ball mount that stays installed. |
| Anti-rattle kit sized to the tube | One and one quarter inch or two inch kits that wedge or clamp for that receiver size. Match the kit to the tube, not to a wish. |
| Receiver cover alone | Keeps grit and spray out of an empty tube. Helps cosmetics and winter mess. Does not replace a clamp when a mount is installed and still chatting. |
Parts-counter shorthand: if the tube is empty and you only want less road grit and a cleaner look, start with a cover. If a ball mount or rack is installed and still knocking, move to an anti-rattle pin, clamp, or sized kit. A cover will not quiet a bouncing shank.

When a cover helps — and when it does not
A cover is the right tool for an empty receiver that collects salt, slush, and gravel. It keeps the tube mouth cleaner and the bumper look neater. It is the wrong tool if you expected silence from a bike rack that still has play at the shank. Quiet the mount with anti-rattle hardware, then use a cover when the tube is empty again.
Locks are a third conversation. A hitch lock is about theft resistance and a secure pin story. It may feel snugger than a plain pin, but it is not sold here as a dedicated anti-rattle device. Open the cover-versus-lock guide when you want that shopping split spelled out.
Empty tube
Cover first
Grit, spray, and looks. Pair with the rust and salt care habits if you drive salted roads.
Mount installed
Clamp or kit
22320, 22323, 22321, or 22315 depending on tube size and how aggressive the chatter is.
Pin basics
Right diameter
Five-eighths versus one-half inch matters. Wrong pin size is a safety problem, not a noise tip.

A simple noise checklist
Step 1Confirm tube size
One and one quarter inch or two inch — match kits and covers to the receiver.
Step 2Seat the pin and clip
A missing clip or undersized pin can sound like a broken hitch.
Step 3Add anti-rattle hardware
Pin and shim, clamp, or sized kit when the mount still chats.
Step 4Cover when empty
Use a cover for grit and cosmetics, not as the only quieting plan for a loaded shank.
