Beaver Patriot Thunder Wheel Bearings, Steering Axle

Our rig didn't come with wet hubs, since some manufacturers feared brake contamination due to oil leakage.

The 2007 Patriots are unique in that they come with Dana Spicer Axle beams that during assembly were fitted with another hub end, in our case a Webb 2574.

While manufacturers vary, the concensus for repacking seems to be every 24 months under our usage conditions.

Some detractors of the wet hub conversion point out that bearing service still needs to be done at this interval, i.e. checking cones, cups, seals and verifying endplay.

I'd sure like to hear from some of our heavy truck experts, get their opinions.

Calling the new Monaco outfit simply got me transferred to Dana Spicer. The Spicer folks then transferred me to Webb. It was Dallas Garrison at Webb who finally specified that those of us with these Webb hubs need the following items to service our steering hubs:
  • Inner Cup HM212011
  • Inner Cone HM212049
  • Outer Cup 3720
  • Outer Cone 3782

  • Seal # Stemco 383-0136

Since technical data for the Roadmaster Chassis, particularly in this configuration, is sorely lacking, can anyone confirm this information or provide additional guidance?

There has been a thread about these front axles, with axle grease instead of the oil bath hubs. What I gathered from the thread was the axles with grease in the hubs have a grease that was good for 100,000 miles. My coach has the axle grease hubs, so I've quit worrying about them.

Back in the day when trucks had non oil bath hubs it was around 100K miles to service.
On my 06 Beaver PT I've pulled the front caps a couple times and they are full of grease that looks brand new. I also check the temp of the front hubs while traveling and have not seen any out of normal heat. If the hub gets dry of grease the hubs will heat up real quick.

Most of the Spartan chassis come with oil bath front wheel bearings but the Roadmaster chassis do not. It's difficult to get good service recommendations from heavy duty truck folks as they drive so many more miles than we do. Like the guys above have said, 100k miles is a good service point.

If interested, some of the guys on here have converted their front wheel bearings to Stemco oil bath. Just a warning, you need some very heavy duty tools even to get a front wheel off.
