Have a 2003 Sun Voyager. Had to have the hub seal replaced twice on my right front wheel bearing. Once by an RV service center and again by a truck service center.

Frieghtliner front ends use 80/90w oil to lubricate the wheel bearings. The front bearings are sealed. If you're leaking oil, it can get absorbed by the brake pad. When you use the brakes, you generate heat, which can ignite the oil soaked pad and cause a fire. Not only can you damage the bearings, you can burn your rig. Get it repaired ASAP! It's not that expensive, new seals maybe $20, about an hour of labor per side.
