I have a 2002 Suburban, 4x4, with no issues.

I want to know what I should do now that it has rolled 100,000 miles to keep it rolling another 100,000. Just changed the oil, air filter and tire rotation.

In a few months I plan on driving it cross country from Seattle to NY and want to enjoy the trip without worrying about the truck.

What preventative tips should I do now?

I always do everything GM recommends (or let the dealer do it). Based on the info at, here is what I got. This first part is for the GM Oil Life System Maintenance schedule. They normally split this stuff up so you only do some of it one time, then the rest another. It's quite a list though
Chevy Parts


Change engine oil and filter. Reset oil life system.
Lubricate chassis components.
Visually check for any leaks or damage.
Inspect brake system.
Check engine coolant and windshield washer fluid levels and add fluid as needed.
Rotate tires and check inflation pressures and wear.
Inspect engine air cleaner filter or change indicator (if equipped). If necessary, replace filter.
Inspect suspension and steering components.
Inspect engine cooling system.
Inspect wiper blades.
Inspect restraint system components.
Lubricate body components.
Check transmission fluid level and add fluid as needed.
Check transfer case fluid level and add fluid as needed.


This includes those things you should do every 25k, 50k, and 100k.

Inspect exhaust system for loose or damaged components.
Interval: Every 25,000 miles.

Inspect fuel system for damage or leaks.
Interval: Every 25,000 miles.

Vehicles without a filter restriction indicator only: Replace the engine air cleaner filter.
Interval: Every 50,000 miles.

Evaporative Control System Inspection
Inspect evaporative control system.
Interval: Every 50,000 miles.

Transfer Case Inspection

Replace the automatic chevy transmission fluid and filter.
Interval: Every 100,000 miles unless the vehicle is mainly driven under one or more of these conditions: 1) In heavy city traffic where the outside temperature regularly reaches 90 F (32 C) or higher, 2) In hilly or mountainous terrain, 3) When doing frequent trailer towing, and 4) Uses such as found in taxi, police or delivery service. If vehicle is driven under these conditions, change every 50,000 miles.
