Earlier this year I needed to use my winch for self recovery. The nearest line attachment point was off to the side a bit, but I got out without much struggle. There was however a bit of collateral damage. It seems that the winch line dug into the vertical roller on the passenger side. Both vertical rollers would not turn by hand, but the horizontal ones were fine.
Finally got around to taking it apart today and found that both the vertical shafts were quite caked with rust. All cleaned up now and ready to reassemble. I am convinced that the rust is caused by water getting by the snap ring at the top and running down the shaft. I really would like to seal the shaft, but short of that I will just put some water proof grease on the shafts.
Any other better/different solutions come to mind?
