If you ever wondered in the middle of the night: "I wonder what my 4X4 center dash mode switch looks like on the inside?" Well, wonder no more........

I stuck Pep Boy's Starfire Solarus tires on my 2003 Envoy. Nice smooth ride now. Bought a spare aluminum OEM rim to replace my original rusted rim and the 2003 Michelin still stuck to it! It had never been used in all these years. So, now I have a 5-tire rotation system. :blinkhuh:

Just joined the hub/wheel bearing club at 133,250. NAPA product left side only for now. I am going to order a Moog for the right and see what lasts longer. The left side replacement had to be done immediately so NAPA got my order. Rock Auto gets the right side Moog (for less than NAPA!) It so...

It's a cheaper fix to just replace it all. I have a 2003 I6 and it was throwing Evap Codes. I had to replace the entire rear fuel/evap system to get it to stop. Pressure Sensor, Fuel Filler Hose, Filler Hose extension to the tank and the Evap canister. It took about 3 hours or less with the tire...

Just did this on my 4.2, but managed to knock the shift linkage around enough so it pop off two days later. Man, that is one annoying fix to have to limp home after throwing it into DRIVE while the SUV is running.:Banghead: Thanks Dorman for making good replacement parts here.

I plan on replacing the thermostat, water temp sensor and right side CV diff gasket/seal this weekend, but I found it was cheaper to order an entire crow-foot ratchet box end set than getting a single one! RockAuto keeps getting my business for a reason.

Maybe it just an age issue? My 2003 Envoy only has 130,000 miles on it.

Just replaced the upstream O2 sensor due to rough idle and actual engine stalling while parked! Worked like a charm. Took it out for an 80 mile round trip on a 95 degree day and it's back to purring again. I would like to thank everyone who posts working fixes to these wonderful rides. If I had...

Purge valve and solenoid. This is the one I found a better way of removing:

I just solved my Code P0440 Evap code for my 2003 Envoy i6. It started a few months ago and I replaced (over time) every major component in the following sequence and the results: New fuel cap. (did not fix the issue) Fuel pressure regulator and the vapor canister fuel purge valve (did not fix...

I had this happen two years ago on my 2003 Envoy. Brake switch was replaced. They wear out from all the sliding on the brake pedal mount. Takes a few minutes to replace, but it is easy to do. I saw another GMC with the exact same problem not a week later and got the guy's attention and told him...

Forgive me Father Mooseman, but I have sinned mightily. Despite your sage advice (buy the entire lower control arm) I went ahead and decided to replace all three of the lower control arm bushings and have spent most of the day hating life itself - as you said I would. I got the strut and...

I would pull the intake off and completely clean the Airflow sensor and the entire intake and throttle body at this point.

Trust me....the lost foam method guarantees oil gets to every bearing as shown in this cutaway

Thanks. I will double check the part number. I did get a few different ones at the same time (parts cannon philosophy 😺), but it is possible I grabbed the wrong one.
