I hate to admit this but I had not really paid much attention to "normal" maintenance needs on my truck since I bought it used 4 years ago with 56000 miles on it.
I changed the oil regularly but that was about it. Now that I am paying attention I am kicking myself in the butt for not doing this sooner.
Right now I am trying to catch up on all the maintenance that should have been done up to 100,000 miles. Better late than never I guess.
So far what I have done (please let me know if I missed anything):
Coolant (which should have been changed at 45,000/75,000/105,000 miles - every 30,000 miles seems excessive) This was done last week at 97,000 miles. Drained, filled with water and cylcled through engine 4 times to make sure 98% of old antifreeze was removed. Word of warning, when you drain the radiator there is still about 5 quarts left in the engine. After filling and draining 4 times that was 98% water but it needs to be accounted for when adding anti-freeze to get to 50-50 mix. Capacity on the coolant system is 13.2 quarts so put 6.6 quarts of antifreeze in and then top with two quarts of water.
I did not see a schedule for changing Power Steering fluid but what I had in there was dark and dirty so I sucked it out and replaced it with fresh Castrol Mercon ATF. I actually did this three times to make sure I got 90-95% of the old power steering fluid out.
Upper and lower ball joints were replaced three-four weeks ago.
Shocks were replaced three-four weeks ago.
Cleaned MAF sensor.
Tried to clean IAC valve but that did not solve the problem so I replaced it with a new one. Now my truck sits at approximately 700 RPM without moving once it is warmed up.
Left to do:
Replace spark plugs and spark plug wires.
Replace brake rotors and brakes.
Replace inner/outer wheel bearings and seals.
That should catch me up on the normal maintenance and replace neglected parts (rotors, brakes, etc.)
If I am reading the transmission code correctly I have a 5R55E 5 speed transmission and per the normal maintenace schedule the fluid should not have to be replaced until 150,000 miles. Seems like a long time between fluid changes. I am thinking about draining the pan and replacing the filter on the next oil change - Is there any benefit to that or is it a waste of money and time? Also, is there any reason I should not do that?
Any suggestions on what else I should do is greatly appreciated.
