300k Mile Tune Up

[93gmc$$]

My old sierra 4.8 Z71 is getting closer and closer to that 300k mile mark (currently 284,6XX). I've compared the cost of buying a new vehicle vs that of repairing one as at breaks so I've just decided that come income taxes I'm going to do a full tune up, not just the engine but the whole truck bumper to bumper. I'm wondering what is normally done in a tune up and what all i should look for when i begin replacing parts.

Just a little history on the truck:

* I'm the second owner, bought it in 2007 with 241k miles on it and still in great shape (belonged to an old man that used it to drive 100 miles to and from work each day).

* It was my first Z71 and I'm still young so needless to say it's seen plenty of mud riding and trips to the woods for hunting and fishing

* been used to the full extent of a truck. I do not drive this thing like its a car!

 

I have no clue what maintenance the last owner performed but i have replaced:

* tires in 2009

* alternator and sears die hard gold battery in 2008

* shocks and sway bars in 2009

* both rear u joints in 2009 and one in the front a few months ago

* spark plugs and wires in 2009

* transmission at 278k miles (few months ago)

* front driver side hub assembly 280k miles

* water pump a couple weeks ago

* spectra cold air intake and true dual straight exhaust (cats only) at 280k

 

This truck has been great for me and im hoping it last well beyond the 300k mark so any tips and advice would be greatly appreciated.

 

Maybe O2 sensors and check the brakes

199500 miles and she still going good! GM did something right with these GMT 800's from 1999-2002!

 

yes they did. basically regular maintenance and some TLC and they just keep going and going. good luck you've still got a lot of miles left to put on that thing

 

Amen to that, i plan on driving this truck till it literally wont go!

 

 

theres very few of us 99-02 GMT800 trucks on this forum

I know everybody is buying the brand new silverado's, these 99-02's are a beast of truck!

you might want to also look at changing the fuel pump. mine went out on my 01 silverado a few months ago. its not too hard of a job. had to siphon a full tank of gas out but i did it myself in 4 hours. thats with beer breaks and trips to the auto store.

i'm thinking its about time for one anyway. i have trouble starting sometimes. everything is turning over just fine but every once in a while i gotta pump the gas peddle to start it up

I just joined the forum a few minutes ago and have had great luck with mine....bought it 10 yrs ago @70k miles......I just hit 270k. I did ball joints, a/c compressor, fuel pump and belts....that it. Nothing else.......The only thing that doesn't work......the ONLY thing is the light bulb in my ashtray. Wish there was an easy fix for that.....Other than that.....just gas, oil, filters and TLC.......I'll run her forever.....regardless of what she needs.......
