My 5600 toolcat has developed a screeching noise which seems to be coming from the left front (?under left fender well, ?steering column). The noise gets worse the longer I run the machine and is worsened by turning the steering wheel. Today, the machine began overheating, making the screeching worse. All filters, radiator screen, oil cooler area, etc. are clean. Am not getting any warning messages. Hydraulic fittings feel very hot. Would appreciate any thoughts as to what the problem might be and/or what I might do to trace the problem down. Thanks
