2007 Impala rear tire wear due rear wheel spindle rods

This is the bulletin put out by GM, it applies to police cars. but from our Impala tire wear and reports on the net I know it's not just police cars. my husband called GM, the person on the phone didn't seem to know about it. he'll receive a call back and is to take the car to the dealer (who is the one who told him about the problem) and the dealer is to contact GM to say what's wrong. how can GM reps not know?? seems GM is thinking "ignore the problem and it will go away."

the solution is to replace the rear wheel spindle rods.

Component Description:
11. WHEELS Bulletin Number:08032
Bulletin Date:Jun 2008

Vehicle: 2,007 Chevrolet Impala
Summary:
GM: A CONDITION EXISTS ON YOUR POLICE VEHICLE THAT MAY CAUSE REAR WHEEL MISALIGNMENT, RESULTING IN LOWER TREAD DEPTH ON THE INBOARD SIDE OF THE REAR TIRES. CSC LETTER. ( NHTSA ITEM NUMBER - 10026504 )

    our problem was solved in 2009 by the Chevy dealer ordering the necessary parts under our warranty. he had the info of what was needed. the car was low-mileages and so it was covered. (we also had bought the extended warranty.) the Chevy rep on the phone was very nice but couldn't do anything without the supervisor's okay and they would not pay for the back tires. this couldn't be handled as a recall.



    our 2007 Impala is not a police car but still had the same problem! the tread wear was as explained in the bulletin and our car had only 12,000 miles on it when we bought it in 2009.

    there had to be alignment after the bad parts were replaced.

Nick52284,
I have gone thru 3 sets of good tires now. Tires lasting from 10-12k miles before they hit cords. This is after the dealer does an alignment to spec. Funny thing is I have never seen the alignment specs from the dealer, I only get "aligned to spec". My wear is on the inside of the tires just as described in the police bulletin. I have tried different brands each time and get the same result (wear to the cords in 6 months or less). The bulletin only applies to the police version becasue GM doesn't want the bill for the thousands of ordinary customers repairs. There are enough complaints of this exact thing on any Chevy site that you can find. We aren't all nimrods.

You may be a guru, but I think you don't know what you are talking about.

We bought a 2008 new and went thru 3 sets of tires by 24k. Almost killed my family because the car would hydroplane on wet roads at any speed. We finally parked the car at dealers lot and have refused to drive since oct 09. GM offered us $1000 voucher towards purchase of another GM haha our lives are worth $1000 bucks. Filed complaint w/NHSTA and contacted my Senators/Congressman for help. GM knows they have a problem with this model and are not admitting it FILE YOUR COMPLAINTS w/NHSTA and lets force them to admit the problem

I have the same rear end tire alignment problem on my 2008 Impala. I have now gone thru 2 sets of tires. Most current one lasted 7 months, 12k miles. Tires are rated for 60k miles. The inside of the tires are getting chewed up.

I've looked at the car from the rear and I can see that the alignment is poor, the tires bow out at the bottom as if there were way too much weight in the car.

I'm calling the dealer on Monday to see what can be done, this is a ridiculous issue to be fighting about. The manufacturer should cover this no questions asked. My wife (a civilian) drives like a grandma, there's no way we caused this.

The reason the bulletin only applies to police edition vehicles is because the suspension is different on those police package cars, the suspension is stiffer and has bigger sway bars for pursuit purposes, i have seen problems with civillian impala's but its not because of the spindle rods the problem is because of crappy tires. those goodyear integrity's have issues with the OUTSIDE tread wearing faster, the bulletin is for inside tread wear, also being that your car is going on 3 years old yes 3, check the build date, it is a normal maintenance item to have the alignment done at least once a year.

    if your wearing tires out to the cords in 6 months then you have a very serious problem with your rear suspension thats far byond the bulletin. if you didn't buy the car brand new i'd honestly check into a carfax for any kind of side or rear end collision. even if that bulletin does apply to your car for some unknown reason, that still doesn't justify the kind of wear your explaining. so again your problem is something more severe than what the bulletin states. if the wear your complaining about is as bad as you say it is, there would be a safety recall not just a bulletin.....

    also

    i don't appreciate you saying that i don't know what i am talking about. i work for, and have worked for a gm dealer for years now. not once have i seen a civillian impala have the rear spindle rods replaced. i'm not blind and i'm very good at what i do. you can't argue with a 4.0 out of 4.0 customer satisfaction rate 3 years in a row, and yes i am a technician, how many cars have you personally fixed to give you the right to say i don't know what i am talking about? if you've been working on cars for more than 11 years then by all means i apologize!

This is a GM failure new tires will not fix this! It will not go away without a major fix not even with alignment! original specs are no good! If they aligned to spec its a waste of ur money and time!

Rods in rear are bent causing tires to wear


do you mean the tie rods or are you just looking there and see a part that looks bent? if both tires are wearing uneven, it could be just a rear wheel alignment that you need. did you just buy this car? it's possible something under the car is bent from a previous accident, but if you had this car for awhile and this problem just began then it may be just an alignment........good luck..p.s......if both tires are wearing uneven then it's unlikely a" rod "is bent , there would have to be a " rod " bent on both sides which is too coincidental.

Customer wants to run rear tires at 60psi instead of the recomended 80 psi. Can the tire pressure values in the computer be reset so the tire pressure light stays off?


hte pressures can be set but GM has sent out a bulletin that anyone doing this would be held personally liable. so you most likely wont find a dealer that is going to do. reason being if a tire fails due to underinflation gm does not want to be in middle of lawsuit

The abs and trac lights stay on when the engine is running. how do I fix the problem ?


Something as simple as a different tire size can cause the abs to go nuts. I even had it where the two tires were the same size. But a different brand name. Each manufacture has their own tire sizing so not all tires a equal in size. Even though it says on the side of the tire that they are the same size.

Sometimes the cooper inside the insulation of the wires going to the sensors corrodes. Especially on the front units. It reads more ohms than normal but not open and is very intermittent. However moving the wires my make it work for a while. That's why replacing bearings seems to fix the problem but it comes back after a while.

You can test the speed sensors yourself...
Front sensor specs:
956 to 1240 ohms in 41 to 110 degree weather
at least 100mV AC (NOT DC!) volts when hub is spun by hand
Rear sensor specs:
950 to 1300 ohms in 41 to 110 degree weather
At least 100mV AC (NOT DC!) volts when hub is spun by hand

Here is some information from service bulletins that could be related to the problem. The traction control, antilock brakes, and tire inflation monitor all use wheel speed sensor input.

This first bulletin seems like it could be the problem because engine movement is involved:

GM Corporate Bulletin 00-06-04-049B
This Bulletin covers a problem that can cause multiple failures, one of which is an Antilock brake problem, and covers 2000-2003 Impala and Monte Carlo built prior to 2/03.
Check to make sure the wiring harness adjacent to the AC accumulator/dryer is not rubbing against the ac accumulator chaffing through the insulation of the wires in the harness.

GM Corporate Bulletin 03-05-25-008 overview:
GM front wheel speed sensor harness replacement - 2001-2003 Buick Century, Regal; 2001-2003 Chevrolet Impala, Monte Carlo; 2001-2002 Oldsmobile Intrigue; 2001-2004 Pontiac Grand Prix
This bulletin is about inspecting the harness going to the front wheel speed sensor for wear from contact with front suspension parts.
Repair harnesses/leads are available that can be spiced onto the main harness.
2001-2003 impala & Monte Carlo – Right side - 10340313
2001-2003 impala & Monte Carlo – Left side - 10340314

Im look for the name of the bar that hold rear the wheel in place


There are 3 rods in the rear that attach to the rear knuckle, two that run side by side. The one closest to the front of the car is the front spindle rod, and the other is the rear spindle rod. The bar that runs from the back toward the front is the rear trailing arm. I hope this helps.

2008 Impala wearing rear tires poorly. I understand this is due to not being able to perform canber adjustment due to type of struts used. Is this correct and can this be solved?


check your rear suspension very carefully, something may be bent. all adjustments should be able to be made otherwise GM would not publish alignment specs

Rear wheel Alignment


First of all Calling Gm wont do any good.Keep all documentation and start taking idiot mechanics to small claims court.I have done this many times due to faulty work.Judges hate mechanis.I have won evertime 3/3.I keep great records thogh.I have a 2008 Impala ss and I have the specs for alignment in front of me.Tire Plus told me that alignment was find and had to show them that it is simple math and the bright red numbers under actual on the toe are telling you to look at it its off.The problem is you have to take the car to a place that actually has Mechanis aligning the car.Most shops use alignment techs which basicakky means hello I am a moron I will mess your car up worse,because I am an idiot.If its not right demand a refund.Also demand before and after specs.Even though the numbers might be in specs,If the numbers on each side dont match closlet the car will still not drive corrctly.

2002 E320. Premature tire wear on right rear wheel.


THese cars have a high speed rated tire and will almost always wear quickly. The right rear is the drive wheel (where the power goes when you give it gas) It will wear real quickly if you drive it hard. I would try rotating every 7500 miles (unless tire sizes are different as with the SL series) I sell a lot of tires on these cars and 25K is usually the limit.
