🛠️ How Much Grease Should You Use When Packing RV Bearings?

Properly greased wheel bearings are essential for safe and smooth RV travel. Bearings support your trailer’s wheels, and without the right lubrication, they can overheat, fail, and leave you stranded on the side of the road. But one of the most common questions RV owners ask is: “How much grease should I use when packing my RV bearings?”
At RV Rescue Rangers, we’ve helped countless RV owners maintain their rigs, and here’s what you need to know about bearing grease.

✅ The Right Amount of Grease
When hand-packing or using a bearing packer, the goal is to fill all the spaces inside the bearing with grease—but not to overload it.
Fully Packed: Push grease into the rollers and cage until it comes out the other side. Every surface of the bearing should have a coating.
No Excess: Avoid filling the entire hub cavity with grease. Too much grease can create heat and pressure as the wheel spins, potentially damaging seals.
Light Coating on Spindle: Add a thin layer of grease on the spindle and races before reassembly for extra protection.
👉 Think of it as enough to fill the bearing itself, not to stuff the hub like a grease bucket.

⚠️ Common Mistakes to Avoid
Overfilling the hub – Can cause seal failure and messy leaks.
Under-greasing – Leaves dry spots that lead to overheating and bearing failure.
Mixing grease types – Always use the same type (lithium or synthetic, high-temp rated for trailers/RVs). Mixing types can cause breakdown.

🛞 How Often Should You Grease RV Bearings?
Travel Trailers & Fifth Wheels: Inspect and repack every 12 months or 12,000 miles, whichever comes first.
Heavy Use or Mountain Travel: Consider shorter intervals, since stress and heat are higher.
