I’m looking for some ideas. Here is the scenario: I’m hauling a load of fire wood home yesterday. The truck is loaded with wood racks and I’m pulling a loaded trailer as well. Came off the hill in 4 low, stopped on the main county road and ate lunch and checked everything over. I switched out of 4 low and back in to 2wd. Once I got up to about 35 mph, she starts drifting funny. I’ve driven this truck for 17 years, so I know it’s habits like the back of my hand. I stop and check everything again, but can’t see anything standing out. Continue on for about another 6 miles, 2 of which is pavement. She’s a acting real funny up front by this time so I pull over . I’m looking at the front driver side tire and it is chewed to beat hell. Not uneven, but chunks missing out of the lugs. Have it hauled in to the shop and the mechanic goes over everything and can’t find anything wrong. This is a good mechanic that has years of experience. The steering components are shot, but they have been for a while. He is redoing the steering components. Hopefully this is the problem, but I don’t think it is.
