Chevrolet - Silverado1500 :: 2005 - Thumping Noise Randomly
Jul 14, 2012
I drive a 2005 Chevy Silverado. I only drive a few miles a day, to and from work. The truck has about 32,000 miles. Recently it has started making a thumping noise, but only randomly. From inside the truck, it sounds like someone is knocking from under my hood while other times there are no unusual noises. I opened my hood while it was making the thumping noise but couldn't hear it from outside the car. Doesn't seem to make a difference what I do - put it in drive, neutral, reverse, park, go fast, slow, stop.

I have a 2000 Chevy Silverado pickup, V8, A/C, 105,000 miles, which drives like a top.
However, about a year ago, the TWO brake lights on the dash started coming on together, randomly. Sometimes the lights came on right after I started the first time, other times, they came on later in a trip after the truck warmed up.
The brakes worked perfectly, as far as I could tell. I took the pickup to the dealer, left it 2 days, and they checked the brakes, belts, tried everything (they said) including trying to get error codes on the computer. Trouble is, the lights had mysteriously gone out and refused to come back on.
A few days later, they came back on for me!! I could turn the truck off, wait a few moments, restart it, and the lights would go off, say, 80% of the time. Only to come back on later. So, I took it to a local Goodyear Tire store (while getting new tires) and they saw the lights, did a diagnosis on a computer, and got NO codes.
Now, I'm worried very much - you see, the brakes on this truck have never been changed! I've had them checked many times, always with the answer that they are still in great shape - last time, they had 30% left! I waited until the lights were ON, and drove all the way to the dealer; parked the truck running; and waited until a technician could come out and do the computer test. NO codes.
Now, I have noticed a possible pattern: when the weather is hot, as it has been most of last year here, the lights come on; when it's cold, as it's been lately, the do NOT come on. Just today, the weather warmed up into the 70s and, zap, the lights came on today.

My dad recently asked me to find out what is wrong with his A/C unit on his truck. He has a Chevy Silverado 1500 LS. it's a 2002 model. um.... anyway, he usually blasts his A/C around 3 to 5. the a/c setting goes from 1 thru 5, and off. so i was thinking that since he uses the a/c so much that he's gone and broken something.
In the middle of summer so i suspect the heat has something to do with it. some days the a/c works, sometimes it doesn't. although i've ridden in the truck a few times since the problem appeared, I've noticed that the a/c almost always works when we pull out of the garage or when its cool enough. and never works when we come out of a store or somewhere to the truck that's been left out in the heat in the parking lot.
There's one more thing. i haven't noticed it yet but this comes directly from my dad. he says that sometimes he'll just be driving along and he'll hear a 'clunk' noise and the a/c will start working again. How to fix this problem. I assume this is something very common. and would it be easy for me to fix? i know more about computers than i do cars, and I've already taken apart 1 laptop and fixed 2 others. I feel fairly confident taking part of a car apart.... er, truck in this case.

I've been having this problem for a while now. Specs: 2003 Silverado-1500 with 260,000. New wires, plugs, fuel filter. I clean the Throttle-body and Mass-Air-Flow Sensor every two weeks. I use Techron fuel additive @ every fill-up. I have also tried using Seafoam Motor Treatment in the tank and crank-case. It turns-over but won't start. I have to try 3-4 times before it starts. The only time it starts on the FIRST try is when the gas tank is FULL.

I have a 95 Silverado 1500 with the 5.7 V8 that cuts out when the pedal is held just above idle. If I am just driving normally as in pulling up to a stop sign and leaving with moderate acceleration it is fine and I don't notice any problems at all. The time I really notice it is when I am backing a trailer up and have to hold the pedal just above idle. It acts like the fuel is just being shut off to all cylinders. When I let off the gas it will sound like it is going to die and then it will come back to idle and idle perfectly. I was told it was probibly the PCV valve and I figured that for a few bucks I didn't have much to loose but that didn't work. I am thinking it has to be a sensor but I may be wrong.

I have a vibration in my 1997 Chevy pick up that comes up through the seat. Before this vibration I had steering wheel only vibration and could tell it was the front left wheel. Called my usual, trustworthy shop. I did not talk to the service manager, he was on vacation. The owner’s son took the order and the next day I ended up with two new u-joints. Now I have the steering wheel vibration AND the “through seat” vibration. Service manager returned from vacation and took over. The left front tire finally got balanced, like I asked for initially. That tire was 4 ounces off. ALL tires got balanced. Steering wheel is OKAY, no steering wheel vibration, but vibration through seat is the same. The shop changed the u-joints with GM brand u-joints.....no change. We put new tires on...no change. We put a set of different new tires and a set of wheels off a Tahoe.....no change.
Balanced the drive shaft...........no change. In the midst of all this the rear seal at yoke starting leaking. The shop installed new seal and bearing. The shop did pay for the second set of u-joints, the second set of new tires and used Tahoe (but nice) wheels, the seal and bearing and balancing of the drive shaft. I was politely told that I am now on my own. I can feel this vibration at 20 mph, kind of subtle, but noticeable. At highway speeds the vibration increases, not violent, but very noticeable. Once in a while (very seldom) the vibration on the highway is subtle like it is at 20 mph. Then I will go into a slow, long curve on the highway and that seems to set it off. Maybe this is a coincidence, maybe it would happen anyway if there were no curve and the highway were straight. 95% of the time the highway vibration is bad and I can see the console arm-rest shaking. The truck does shake a little when idling, but it always has.
1997 Chevy truck is four wheel drive, 350 with 185,000 miles. This is my work and fishing truck. I am up and down the highway to St. Louis, Mo. daily (construction worker) and that relentless “through seat” vibration is taking a painful toll on my back. Starting to panic. Do not what to address next and worrying about spending a lot of cash trying to do away with this vibration. Work has been terribly slow and I need to resolve this issue.

Just this morning I noticed that the first shift my automatic transmission makes is not so smooth. Almost like I'm getting a slight shove from behind. Repeated at every stoplight. I know I'll be calling the dealer tomorrow, but am hoping to get ahead of the curve and be prepared for what it might entail.

My pickup always bogs down going up a grade, seems like its flooding out and it starts running real rough and vibrating bad, I have to let off gas and pull over .
Been to shop several times, no one seems to know what's causing it.

My 1994 Silverado 1500 has been running rough, chugging, smelling gassy and sometimes quitting while idling. We replaced the plugs and wires. This didn't actually work, but while testing it, it started to overheat. We added water and the water squirts out everywhere from the bottom of the engine. So there are 2 problems...

I have a 2005 Chevy Silverado, and recently it has been running hotter than usual (I dont know the exact numbers, but it usually runs at the halfway mark, and is now at the 3/4 mark) and the heater doesn't work... as long as I'm going UNDER about 60 mph. When I get on the freeway, the water temp goes back down to the 1/2 mark, and the heater comes on! Occasionally when I'm going around 30 or even stopped the water temp gets even hotter, and it tells me that the engine coolant is hot. I've tried adding more coolant... maybe I have a leak? I also know that I need new AC/Serpentine belts, could it have something to do w that?

I have a new issue with my '02 Silverado, which so far has been a good truck. However, about a week ago when I tried to open the tailgate, the latch wouldn't release. I have yanked on the tailgate with my full weight (260 lbs) while pulling on the release handle, and have not had any success at getting it open.
The release handle seems to work OK, but the internal latch mechanism seems to be jammed in some way. I have even tried parking the truck on different surfaces, just to see if tilting the truck at different angles would loosen the latch, but that didn't work either.
It's as if the tailgate were welded shut. fortunately, most stuff I put in the bed isn't too heavy for me to lift over the gate or the bed sides, but I'd really like to have my tailgate working again. I have even thought that if I do get the gate open, that I'd disable the latch and install a hook-and-chain setup like what trucks had in the early 1960s and prior (since it's a work truck and I'm not planning to part with, it I'm not concerned about resale value).

Dealer replaced rack,twice. Still thumping,they installed new struts and 4 sway bar links and bushings same thump still there. I unhooked swap bar links and tied them to brake line and backed it out is my shop and thump is still there and sounds like both sides. This van has 56,000 miles on it and the ball joints and control arms feel and look tight. Is there anything about how frame mounts that might cause this?

I recently replaced the fuel pump and afterward started noticing a buzzing/whining sound coming from under the hood. The noise goes away when I remove the vacuum line from the fuel pressure regulator and after the car has been driven for 1/2 to 1 hour. Sometimes it comes back, sometime not, but it always is there at a cold start. Had the shop take a look and they said the fuel pump is ok and recommended replacing the fuel pressure regulator. I did but that but it did not solve it. I suppose I should check the fuel pressure. 2000 Silverado 5.3L ...

I replaced both 1/2 axles last week after one CV boot pretty much disintegrated. Since it is a 2005 Acura TL with 146K miles, I changed both axles completely. BTW - I had NO forewarning, noises, etc. before the axles died last week! I only perceived an increase in road noise, but did not hear noises squeaks, thumps, clacks, etc.!) The first day I drove the car after the new axles, I noticed a thump, thump, thump from the right wheel area when I made a sharp, slow turn out of my driveway. It only happened once, but it was a quick trip.
The next day, I noticed it again as I pulled out of my driveway and later as I pulled into a parking spot. There are no other symptoms and it only occurs when the wheel is turned to an extreme (80-90 degree) at little to no speed. I tested it in an empty parking lot - slow circles in either direction will cause the thump, primarily coming from the right wheel area. I immediately drove to the repair shop and made an appointment. Why I'd develop a new thump immediately after getting new axles? I'm thinking something isn't right with their installation. Of course, they say nothing is wrong with what they did - the problem now is that I need stabilizer links?! Sounds like BS to me - why all of a sudden do I need BOTH stabilizer links immediately after repair work?

My 2005 F150 is making a thumping noise in the front end. It increases as speed increases and is more pronounced when turning wheel left and almost goes away when turning to the right. Sometimes at higher speeds I can feel it in the gas pedal. Seems to be coming more from the driver side but I could be wrong On that.

This has been a decent truck... lately you drive for 5 miles or so.. it goes to reduced engine power. if you get to side of the road and turn completely off and sit maybe 10 seconds or so, it goes fine again.... I have tried to get a computer reading, but by the time I have gotten it anywhere, the check engine light is off again..

I have a problem with exhaust fumes in my 2003 Silverado truck. Initially, 3 head bolts on the manifold were found to be popped off. After replacing the bolts, the exhaust fumes in the cab still existed. The truck has been evaluated by a Cherolet dealership and 2 independent garages who found no system exhaust leaks. Obviously, I am very frustrated and not sure what to do next or where to go.

Truck has 190,000 miles. First, every now and then the truck won't start. Turn the ignition key to the start position and nothing happens - like the battery is dead. Turn the key back to the off position, wait maybe 10 - 15 sec. Try and start again - starts right up. This maybe happens about half the time I start the truck. Always seems to start first start attempt of the day. Only later does it start to behave this way.
I took it into a repair shop and they claimed it was the starter relay. After the repair (about two weeks) it seemed fixed - started all the time. Then a couple of days ago it began to do the same thing again. Only now, maybe 10 - 20% of the time doesn't want to crank (vice 50% or more before the repair). Doesn't seem to be the battery because when it cranks it cranks very strong and starts right up.
Now additionally, today, the truck just dies while driving. Doesn't stall or run rough just before dying - just dies - like turning the ignition switch to off. Interestingly, it starts right back up after this - no extended cranking, etc., just starts right up. I have tried "jiggling" the start switch to see if maybe it is failing, but it has no effect. That is, when the truck won't crank, "jiggling" the switch won't make it crank, and "jiggling" the switch while the truck is running doesn't cause it to die. Sometimes, the waiting 10 -15 secs or so between crank attempts doesn't work - that is, it doesn't crank, but if I open up the hood and take the starter relay out of its socket and put it back in, it cranks.
