Thanks for the replies everyone. The calipers are fine, were checked at both facilities. The vent hole is also fine, no issues there. I have ordered two of the Workhorse official seals to be delivered to the repair facility in Boston. We are in Danbury, CT for the night and will drive in to Boston tomorrow. I am pulling off every 100 miles and refilling the hub with a mix of synthetic and Lucus hub oil and it seems to be doing the trick...no heat issues today. What I am really hoping is that the wear ring from the original WH seal is still in the hub and is the culprit since it isn't compatible with aftermarket seals and will cause them to leak. I will update you all after the next repair. On another forum a poster said that in a worst-case scenario I can just have them pack it with grease to finish my trip and then sort it out from the comfort of home when we aren't in the middle of a massive trip.
