Bulletin No.: 04-03-07-004B
Date: July 22, 2005
Premature Front Tire Wear (Set Front Z Height, Toe and Rotate or Replace Front Tires)
2004-2005 Chevrolet Colorado
2004-2005 GMC Canyon
Built Prior to November 18, 2004
This bulletin is being revised to add a build date to the Models. Please discard Corporate Bulletin Number 04-03-07-004A (Section 03 - Suspension).
Some customers may comment on excessive front tire wear on the inside edge of the tire.
On four wheel drive (4WD) models, an incorrect Z height trim setting, resulting in an excessive front sum toe-out of specification, may be the cause.
On two wheel drive (2WD) models, an incorrect front sum toe setting may be the cause.
Follow the procedure below for diagnosis and repair of this condition.
Important: Prior to performing any tire repairs, permanently record the current tire inflation on the repair order.
1. Permanently record the tire pressure settings on the repair order.
2. Inspect the inside edge of the front tires for excessive wear.
^ If the inner front edge of the tires are worn to the wear indicators, replace the front tires and continue with the next step.
- For repair information, refer to Tire Mounting and Dismounting.
- For tire warranty information in the U.S., refer to Warranty Administration - GM New Vehicle Tire Warranty Program Bulletin Number 00-03-10-003I, dated June 2005.
- For tire warranty information in Canada, refer to Warranty Administration - GM of Canada New Vehicle Limited Warranty Tire Program Bulletin Number 01-03-10-003B, dated April 2004.
^ If the inner front edge of the tires are not worn to the wear indicators, rotate the tires and continue with the next step.
Important: Prior to performing any additional repairs, permanently record the following information on the repair order.
^ Z Height
^ Alignment Measurements
^ Fuel Level
3. Set the inflation per the vehicle tire placard located on the driver's door.
Important: On 2WD models, DO NOT replace the front coil spring(s) or add insulators to compensate for a low trim Z height. A lower trim Z height reading is acceptable as long as it is within specification. Refer to Trim Height Inspection Procedure.
4. Check and adjust the vehicle Z height.
Important: ON 2WD models, ONLY replace the front coil spring(s) if the trim Z height is too low and out of specification.
5. ON 2WD models, ONLY replace the front coil spring(s) if the trim Z height is too low and out of specification.
6. Check and adjust the vehicle front toe to 0.00°+/- 0.20°.
7. Road test the vehicle in order to verify that the steering wheel is straight.

Shareholder, there is no way you should be wearing out the inside of the tires that quickly. My opinion is that the dealer, even though they are "aligning" your truck, they're not working within the limits of the specs to eliminate your problem.
Many of the newer alignment machines have the "red" (out of spec) and "green" (within spec) scales built into their software, and many of the younger techs simply get the machine's screen "in the green", and proclaim that you're "good". They don't yet have the understanding or experience to diagnose problems accurately, and formulate a "custom" solution to your problem. Also, I'm sure that GM exerts a certain amount of leverage on them to adjust "to the green settings" regardless of what the tire wear is saying.
Well, "good" is still wearing out your tires, so you need an "old fashioned" wheel alignment man that will read the problem, and tweak the specs a bit, to fix the situation. It would appear to me that if you're wearing the insides of the tires, you have either A) too much negative camber; B) too much toe-out; or C) a little of both. Maybe, in order to fix your particular wear problem, your truck needs to be a little in the "red" zone, and you need a front end man that know suspensions, and not just how to turn the adjustment bolts to get it in the "green".
To be honest with you, I DO rotate my tires, but I sincerely believe it isn't the cure for everything. Look at how many cars today have staggered tire sizes, directional tread patterns, or both. Can't rotate the tires on a car like that.....

Shiftright, that's avery interesting post, howver it lacks one important thing...The ride (trim) height measurement!
When I first took delivery of my Canyon, I picked it up in the evening, and it was snowing pretty heavily. Therefore, I basically drove straight home, about 2-2.5 miles, and didn't realy get a feel how it handled. The next day, while driving to work, I was shocked! The truck was all over the road.
I have a general distrust of dealers, so I took it to my trusted front end man a couple of days later, to have the alignment checked, as I felt it HAD to be off....way off! Long story short, the alignment was OK, we bumped the air pressure 5-6 lbs. and the truck was somewhat drivable.
A few days later, I put 4 Blizzaks on the truk, as it was primarily my winter vehicle, and it was like a different truck altogether. The OE General tires were SO BAD, that a good set of snow tires made it handle 100% better!
Anyway, do you happen to know the trim height spec? Just out of curiousity, I'd like to check mine. (It's a 4WD, Z-71) Thanks!
As a side note, I mentioned this in another Canyon/Colorado discussion...I switched to 16" rims and 245/75/16 tires, as well as adding a rear sway bay. It handles quite well now, for a 4x4, that is.....

I bought a 08 Canyon in April and I have idle engine problems that the dealer can't seem to fix. The truck when stoped acts like its going to die and shakes. There are no lights to indicate that there is a problem but its not normal. The dealer has tried re-programing the computer two different times and said they cleaned out the trottle?? GM said that they have the latest computer program that they will have to try but ill have to wait and see. I also have had other problems such as: windsheild wipers going off whenever, seatbelt issues, and backfiring. Any info that could help my cause??

No I don't know where I'd find that measurement. Your alignment guy should be able to find it though in his spec sheets.

I have a 08 colorado 5cyl 4x4. the engine seems to not shift from low to drive. the engine is very loud and truck will only creep. At times it seems to drop to neutral. All this happens at start up before the engine warms up. It will be fine the rest of the day. I had it in to the dealer twrice, but they say it is normal or that the computer says it is ok.

Not saying this is the issue, but the torque converter has a lot to do with your shifting and ability to get up to speed.

I have had the same problem. When I would come to a light my rmps would drop to about 400 and shake. It had 36700 miles out of warranty. They said it was still within the specs and since out of warranty they could noth. $300 they clean throttle and fuel rail and reset computer. 15,000 miles later it began to stall at light about once a week. I refused to take it in, but when it stalled turning left in traffic I had no choice. I told GM Service that I would not pay 300 dollars every 15,000 miles. This time only 89 dollars. They claim that they could not find anything wrong with it because no check engine light on. I also noticed when it was having these problems if you put it into neutral when getting on the highway the rmps would bounce between 400 and 1200.

Now my 2007 Colorado 2wd 3.7L 81,000 Miles is loosing some coolant. About a half of gallon
I am going to wait and see if it continues. Before I take it to the dealer.
