Hub caps (also called dust caps) might seem like a minor accessory, but they play a crucial role in protecting your trailer’s wheel bearings and hubs from dirt, moisture, and damage.
What Are Hub Caps?
Hub caps are the small covers that fit over the center of your trailer’s wheel hubs. Their main job is to seal the hub assembly and keep grease inside while preventing contaminants like dust, dirt, and water from getting in.
Why Are Hub Caps Important?
- Protect Bearings: They keep grease sealed inside the hub, ensuring wheel bearings stay lubricated and protected.
- Prevent Damage: Stop dirt and water from causing corrosion or wear on moving parts.
- Maintain Safety: Well-maintained bearings mean smoother rides and reduced risk of wheel failure.
Signs You Need to Check or Replace Hub Caps
- Hub caps are missing or loose
- Visible grease leaking from the hub
- Dirt, water, or rust inside the hub area
- Damage or cracks on the hub cap itself
Maintenance Tips for Hub Caps
- Check hub caps regularly for tightness and damage
- Clean hub caps and surrounding areas when servicing wheels
- Replace damaged or missing hub caps promptly
- When servicing bearings, ensure the hub cap is resealed correctly
