I have a 2008 Grand Prix Base 3.8L with about 99, XXX miles. Since 30k miles, I've completed routine engine oil changes, 2 transmission fluid and filter changes, air filter changes, MAF and throttle body cleaning, plugs, wires, front pads and rotors, and a few other misc items. The car runs like a champ and has no mechanical issues to my knowledge (other than a local mechanic saying I have some play in the water pump pulley - but not in need of immediate replacement).
This spring I would like to tackle some less frequent but general maintenance items; I'd like to prevent any of them from becoming a surprise/problem. I've done a fair amount of research and have some items in my Rockauto shopping cart to be installed this spring. I would like some input on whether I'm going overboard (since none of these are issues at the moment) or if I've missed a crucial maintenance item.
I'm also having trouble deciding if I should install all new struts and suspension linkages all the way around. At 100k I would think I'm due but I am not getting any noticeable bouncing on the road or if I bounce test each corner while stopped. Also, our family mechanic told me struts can go much longer than 100k depending on driving habits/conditions.
I am looking for opinions and suggestions based on personal experience. Thanks in advance!
