There are a couple reasons to why this is happening to you. One reason may be that your castle nuts are tightened too tight or there is improper lubricant being used. You need to be using high temperature grease like # L11380. It also should be mentioned that it is not a good idea to mix grease types.

It also could be a case of the hubs being overloaded leading to hubs being overheating. The last thing I would check is the brakes. If the drum pad is adjusted too high or if there is a damaged component in the assembly that could be causing excessive temperatures.
