When I was pulling my stock trailer yesterday I pulled over to get fuel. When I got out I noticed a burning smell like I had smoked my brakes a little bit. I walked back to the trailer and noticed that my wheel and hub where very hot on the driver side, and warm on the passenger side. I was almost home so I went ahead and pushed on. When I got home I poped off the greese cap and the grease smelt burn't. I was wondering what this could be. On one side the grease also had a little water in it. = I am not an expert with axles so I am kinda clueless. I also have trailer brakes but no module in my pick up, wondering If they could be locking up. Comments would be greatly appreciated. Thanks Kane
