I have a 1999 Yukon Denali with 171k miles and I'm going on my yearly trip to my cabin in Canada. This is my first my time going on a trip with this truck. The drive is 1500 miles round trip, and we leave on the last week of June so it will be hot. Mechanically it is pretty well off right now with the exception of an exhaust leak that I haven't found yet and the yoke spline clunk. What all should I replace or get checked out?
