my 2 cents:
1. The timing chain stuff is "potential" at BEST. There is NO change interval on the timing chain. The only reason is if it's been overheated, in which case stretch is probable. The way to tell is the color of the painted timing links. Paint there? good to go. Pain not there? change chain, guides, and tensioner. Is head gasket issue due to overheat? then it's possible to be needed, but not at all an absolute necessity.
2. Transmission and differential stuff: Highly suspect I call BS on that. Same with HAVC "vent service" and power steering. Spark plugs? How recently were they changed? if they are les than 20k miles then they don't need to be swapped in my opinion. Sure they are a small cost in that estimate, but there should be no problem with reusing good plugs. Maybe I'm being cheap, IDK...
Agree on changing the water pump, especially if it's the original one. With all on that estimate, I'm surprised the thermostat isn't on it.
If I had to do this right now, I would seriously consider pulling the motor, but that's because I suspect the classic leak in the timing cover, but I really think it's the tensioner cover. I would just make a list of all the annoying things that would best be done with the motor out of the truck and just do a bunch of stuff. I have an engine crane and a couple friends I can call for assistance who are very knowledgeable and keep me from doing something stupid. Plus, I'd like to learn how to do it. But it's my DD, so I would wait until the summer when my wife is on break (teacher) and the kids don't need to get to school, then I'd take the time off work so I'm not stressing at 11pm with parts all over the ground...
I agree with both points. I took the same stance when opting not to replace any timing components. If I had to do this job again, which I am not planning to, I would pull the motor.
