Can anyone recommend a list for maintenance at 100,000k miles on a 2004 Buick Rainier CXL.
I have already completed;

spark plugs plugs
serpentine belt
cleaned the throttle body
fuel filter,

Are there any other services (coolant system, suspension system, etc...) that need to be completed or items that need inspection or grease?

Since you're 2WD, there's no transfer case or front differential, but the Owner's Manual has a nice list. Typically the coolant and the rear diff get done. Suspension doesn't have any greased Zerk fittings unless you've replaced parts with ones that do. If the shocks have never been done, I guarantee they're shot, but they go bad so slowly that many owners don't feel the difference until they change them or drive a newer model.

clean your throttle body . . . it probably needs it anyway

i think he did that :rotfl:

but i would recommend the same things Roadie said... usually fluids get changed at 100k, tranny fluid (pan drop, not a full flush), rear diff, coolant, etc... looks like you covered the other things...

when I did my coolant(at about 6yrs/95k), I went ahead and did my hoses. My Tstat also needed replacing so I did that as well.

Here are a few other items:
Have the brake fluid changed ~$65 to $80
Suck out and refill the power steering fluid through the filler cap. Cheap and effective way toi keep your steering system healthy
Air filter
drain & refill coolant (use only distilled water and a new bottle of dexcool)
change th transmission fluid and include a filter replacement. Costs ~$150 to $175

Good point! At least the upper radiator hose every 2 years or 50k miles. This is the hose that sees hot and cold fluctuations,
