Hello all. I have a ditch witch mx45, same as komatsu pc45mr-1 with 2900 hrs. The right final drive gets weak when the unit gets warmed up. Everything else seems to work ok, no trouble with blade or boom acting strange while digging. This low of hours, do you think the swivel joint could be bad? Am repaintiing machine so I have most panels off right now. Should I rebuild swivel either way? Thanks everyone.
