What to check first
Pull over safely, avoid touching a hot hub and note the wheel location, sound and visible grease.
When to get help
Do not continue towing until axle, hub and bearings are inspected.
Your RV’s make, model and component instructions control. Stop use and seek qualified help for propane odor, smoke, active electrical danger, unsafe braking or other immediate hazards. This guide does not diagnose your RV or establish part compatibility.
Next step
Check the exact component manual and model number before following a model-specific procedure.
