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?
