Chevrolet - Avalanche :: 2007 - Makes Noise At 45 To 60 MPH
Dec 5, 2013
i recently purchased a 2007 Chevy Avalanche 4WD (75K miles) and much to my chagrin, in the first week, i detected a noise that has steadily become worse. the dealership (a Chevrolet dealer) has not been able to determine the cause. I've had it back four times already. The noise always occurs between 45-60mph (not rpm-related) there is a groaning sound and it is accompanied by a vibration in the steering wheel. it is especially notcieable when going around turns in the road at these speeds.
The dealer said it might be related to the alternative fuel management (DOD), but i deactivated the AFM and the noise is still there. I suspected wheel hubs but they checked and said the hubs are fine. The other day as i heard the noise i dropped it out of overdrive down into "3" and the noise suddenly disappearred. All gear shifts are fine, but this was somewhat alarming. I am beginning to think this might be related to the transfer case or front differential? maybe this would be good for "Stump the Chump" ?

I don't know how the story ended with the 07 4WD Avalanche with the unidentifiable noise - he said, "The noise always occurs between 45-60mph (not rpm-related) there is a groaning sound and it is accompanied by a vibration in the steering wheel. it is especially noticeable when going around turns.."He went on to say that he checked the hubs and they were fine, and decided that he would replace the tranny. I sure hope that fixed it.I had the same problem on my 07 4WD Avi, and the hubs checked just fine, smooth as silk, with no loose play at all. But on a 1000+ mile trip just a few days later, the groaning and vibration grew worse, but only when I went around a left curve. I barely made it to my destination - the right hub failed. If it had been groaning and vibrating when turning right, it would've been the left hub. I replaced both at the same time.

I have an 02 Avalanche 1500 4wd z71. It has 173000 miles. Noticed a clunking noise under driver side when slowly taking off. If I floor it there is no sound at all. This only happens when vehicle is on 2wd mode. If I put it on auto 4wd there is no more clunking. The noise sound like two pcs of bare metal are hitting each other. What this could be.

My 2003 Avalanche (5.3L) suddenly started losing oil, 2 quarts since my last oil change (3,000 mi). There is no evidence of it leaking and no apparent smoking, so when I went to get my oil changed today I was telling my mechanic about it. They couldn't find any evidence of a leak either. Then when the pulled the fill plug on the transfer case fluid poured out, a lot of fluid. They are the only ones that service this vehicle so we were puzzled as to how it could be overfilled, especially by so much. Then I got to thinking, the engine has lost about two quarts of oil and the transfer case has mysteriously gained a bunch, possibly two quarts. So the question is, is it possible that the engine oil is somehow moving into the transfer case?

My avalanche ac is not working correctly. The ac is not cold at all and blows out hot air when it stops. I refilled it with freon and it still doesn't get any colder. What might be the problem? And also even though I turn the ac up high, it doesn't blow very hard. (I used the gauge when refilling freon, so no overfilled).

I have a 2002 Avalanche 2500 4w drive with the 8.1L engine. The problem is that it is leaking oil, but only after a long drive. Plus the leak happens like a spray after the car has been sitting for more than 20 minutes. The oil is leaking from IN FRONT of the driver's side front tire and I can't see any oil up on the car. The oil leak only leaks for a short time and then stops until the next long drive. The truck has 118,000 miles.

Have a 2002 avalanche Z71. Transmission was rebuilt 33k ago. It currently shifts a little hard going from 1 to 2nd. Real problem shows up between 40 mph and 50 mph. It suddenly shifts into overdrive which drops the engine rpm waaay down and starts lugging the engine.
Took it back to the guys who did the rebuild. They drove it around and noticed that the computer reported no codes. They claimed it was the TPS and said to replace it. I did. Problem is still there.
Took it to a highly trusted mechanic. They said they think the valve body needs replacing but they don't do transmissions. The guy they recommend drove it around and he thinks it is the torque converter.
I am wondering what causes the computer to decide when it is time to shift into overdrive and I am wondering if there is some sensor that has gone whacko and needs to be replaced instead of starting to tear the transmission apart.

I have a 2005 Chevrolet Avalanche with the 5.3 V-8. When one goes to start the engine it continues cranking (sometimes) after the engine starts and you let go of the key . Sometimes it only does it momentarily; sometimes you have to manually bring the key back so it stops cranking. I have gotten several opinions. Some say ignition switch in the steering column; others say starter/solenoid; others say electrical problem such as a relay. Problem is it only does it sporadically and it never does it when I take it to the shop. What the problem is ?

I have a 2004 Chev Avalanche. Several times recently my check engine light comes on, the truck dings 3 times at me and a dash script tells me to tighten my fuel cap. I do and the light goes out within a few hours or the next day. I have changed fuel caps twice. This week the light came on, has not gone off and at least 3 time it has told me to tighten the fuel cap which I have done.

My 03 Chev Avalanche is giving me a P0300 code (multiple or random misfire). With no distributor or individual coil is this something I can fix myself or is it shop time?

I have a 2005 Chevy Cavalier and have been realizing that the ride has been getting noisier, but when I make a left hand turn ( or even turn the wheel 5 degrees or so to the left) it is much quieter. It sounds like a low vibrating sound and seems to shake the whole front end of my chassis. I can feel the vibration through the gas pedal, and it continues even when in nuetral or without the gas depressed. It is worse between 40-65 mph. Loose parts, misalignment, motor mounts, bad belts? And what it might cost to have this fixed?

I have a 2003 Chevy Cavalier. When I'm going at some speed (not from a stop) to the left (like on a curve), I hear a high-pitch squeaky/squealing noise. It's not one long continuous noise, but more like chk, chk, chk, etc. and high in pitch. It doesn't happen when I'm going to the right. And I don't hear it if I'm going very slowly, such as turning left from a complete stop.
What this might be?

Driver's side strut makes noise, been told by a mechanic it is nothing to worry about just the rubber mount on the strut. Makes noise when accelerating from a dead stop or sometimes turning. It is not a metallic sound. Can i get buy with changing the rubber mount on top of the strut or is it down in the strut itself so the strut needs to be replaced? 1997 Chevrolet Lumina car 4 door....

I am having trouble with my Chevrolet Aveo 2009 A/C. After driving for a while on the highway, the A/C stops blowing much air at low fan and when I increase the fan speed, it blows more air while making a whistling noise but not as much air as it usually does on that same fan speed. The noise starts going away after a while and it blows as much air as it should.I noticed that it happens more when I keep accelerating every now and then on the highway.
It does not happen as much when I am driving on a constant speed. I took it to the dealership and they said the filter was dirty and they found a leak on the vaporizer cap, fixed those but nothing changed! What might be the cause? I was researching the issue and came across this ""TPS (throttle position sensor) gives the WOT (wide open throttle) signal to the PCM to momentarily cut off power to the A/C clutch which disengages the A/C"...Could that be the issue?

Six months ago we purchased a '91 Chevy Pickup and 3 months ago the truck started to "sneeze". Sometimes while accelerating the truck makes a "toot" noise from in front of the driver under the hood, and with the noise I have a momentary loss of RPMs. This can happen a number of times in a row, making pulling out on to busy streets difficult and dangerous. Most of the time, I take my foot completely off the gas and then re-apply it, and the issue goes away. It happens both with a cold engine and a warm/hot engine. This problem started when it was cold out (around 10 degrees Fahrenheit) and the mechanic I talked to about it thought it was the E10 87 gas I was putting in.
I switched to a 97 octane/no-ethenol fuel and the problem went away, until about a week ago when our temperatures finally broke 50 consistently. The problem is back and with it is a minor fluctuation of RPM when idling in neutral. The truck also created a new symptom, I was driving at about 50mph and the truck acted like it slipped on ice... I had evened out my speed and the truck seemed to start coasting then got back to driving at speed, it jerked the whole truck, like driving over a patch of ice. I don't know if it has anything to do with the original problem but all symptoms may be the same thing....
The truck is a 91 Chevy 1500K, 5.7L V8 and has 74,000 miles (mostly highway towing). It had been sitting 2 years, not really being used, before we bought it. We had the fuel injection system cleaned when they did the oil change, right after we purchased the vehicle.

So, I have a 2007 Suzuki SX4, about 172,000 miles on it. Great little car. Love it. It's the AWD Hatchback model.
I recently noticed that it's been squeaking a bit. But only right at start up. In fact, it's summer where I live, and A/C is required just about anytime you go anywhere, day OR night... so, it may have been going on a while without me noticing it. Certainly sometime since the last oil change (almost ready for a new one).
Tonight was typical..... Start the car. Back out. Drive half a block to where there's a stop sign. I hear squeaking when I step on the brakes. Take my foot off the brakes (just to test it) and I still hear squeaking.
I turn left from my side street onto a busier street, hear a bit of squeaking. It goes away. Then I go two more blocks, make a left turn onto an even busier street, where it squeaks LOUDLY while turning left. By the time I drive another six blocks, the noise is gone. Completely.
At first I wondered about the summer heat and the serpentine belt.
The squeaking while turning left made me wonder if it's a stuck caliper.
The fact that it goes away after about a mile of driving makes me scratch my head.
Tonight, I did experiment a little. The car DOES pull -- EVER SO SLIGHTLY -- to the left. But I mean.... just barely to the left. And that could've been because the particular road I was on (when I "over corrected" a little and aimed the steering wheel a lot more to the right, it started to drift right). Alignment was last done a little over a year ago. Maybe year and a half.
So...... I know I should get this checked out. Just looking at what this might be. The fact that ALL squeaking goes away after about a mile of driving.... that seems odd to me... (unless of course it's the belt).

Today I think something went wrong with my starter. When I go to start the sante fe the starter makes a winding noise. Battery tested good and I ensured that the ground was clean and making a good connection.
I read about a TSB relating to a starter arm kit. I can't seem to find a part code or any info on the 2010 specifically having this issue.

2007 ES350. Recently, I noticed when I turn on my engine in the mornings it makes a whistle/squeak-like noise. It the sound continues and eventually fades away as I drive after a mile or two.

I have a 2007 Ford F-150 small box bought new, now has 80,000 miles. The rear end started to make a slight roaring noise that started to turn into a vibration. That turned into a major vibration (windshield wipers would hop). I figured a bad U-joint, but it had no "clunking sounds". I took it to a non-dealer mechanic and he said the "rear end is shot, and also a bad leaf spring..." I do not tow with this truck, or go off road, but it does have a Tommy lift installed. Does this sound normal for the miles and usage of the truck? Any recalls for this model that effects the rear end?
