Out of curiosity, any major components replaced or rebuilt such as transmission, engine, axles?
I have a 103K on my truck now. I have had to rebuild the front-end steering components on my truck. This was done in stages as items wore out. Such as the front brakes were replaced at 72,000 miles when the Front LH U-Joint failed. At 82,000 miles, I replaced the Drag Link after the joint failed and I loss steering. At the same time the Upper & Lower ball joints on the RH and LH side were replaced along with the LH Hub AS with unit BRG and all Tie Rod connections. At 85,000 the A/C failed and the compressor and Accumulator were replaced. I replaced the rear brakes at 99,000 miles.
These are the major unscheduled repairs that I have seen on my truck. The engine and transmission so far have worked flawlessly. I have just followed the maintenance schedule replacing filters and fluids as required.
