Wheel hubs running hot

I have repacked the bearings on our TT before our last trip (200 miles one way) and noticed when we got back that passenger side hubs were rather warn. Driver side - cool as a cucumber. I pulled the wheels off, cleaned everything again, repacked, reseated, etc. and drove around and they're still running warm. Yesterday, while chatting with a friend about it, he mentioned too much weight being on that side. The only thing I can think of is that my WDH is putting more pressure on one side of TT than the other - I tried a couple of changes lately and I'm afraid I need to reset it all again. Has anyone experienced this before? Could it be a possibility?
