Preventive maintenance

I bought a new Toyota Tundra, double cab, with long bed in December 2008. The only things I have ever added to it are running boards and a fiberglass bed cover. It has been an absolutely amazing truck. I have changed the oil and filter every 5000 miles, changed the air filters when needed, replaced tires and brake pads, and I had to replace the battery once. The truck only has 104,000 miles. It has been a perfect machine. Now that I have passed 100,000 miles, I know I should get some preventive maintenance done but when I check online for what's recommended, I get woozy. Dang! I could never afford to do all of that. What steps should I absolutely take now that I have reached this first big milestone to keep everything running well? Thank you for your help!

Instead of checking "online", check the owners manual, and do a little at a time. Because of your good maintenance practices, you've had excellent service from your truck, keep it going!

 

Clean maf and throttle body cheap and easy
All fluids ps, brake, coolant, diffs, and a drain and fill on the tranny. A little spendy but all are overdue
spark plugs probably least important unless your having ignition problems
