Sierra :: 2002 GMC SLE Have Low Mileage - Thumping Or Clunking Sound


Jan 28, 2016

Have been attempting to locate the source of thumping or clunking sound similar to that of bad shock, but too date haven't been able to pinpoint the source....

Have low mileage 2002 Sierra SLE that has a body noise that haven't been able to locate. The sound is similar to a bad shock....Replaced the front shock.....which wasn't 2 years old...and then the noise reappeared again....Have checked the wheels and motor mount...but so far no luck....

It seems to be worse in cooler weather and is reproduced when driving over an uneven surface or hitting a bump....The clunk is intermittent...Sometimes you will get the noise driving over a bump....sometimes not......The noise seems to be originating on the driver front quadrant....but i maybe wrong....

Have had mechanic check the truck on a hoist, but can't find anything out of order...no tire wear...wheels are solid with no play...nothing out of the ordinary that we can see....Tried moving the body by hand..but can't reproduce the "clunk".....

Even after 14 years the truck is solid ...and no rattles or noises until now......Guess i'm just a nit picker...but would like to locate the source......

Ford - Mustang :: Thumping / Clunking Sound Coming From Front End

When being driven my '66 Stang makes a clunking sound in the front end which seems to be coming from the front toward the passenger side.

I've had the car in to my mechanic twice in the last 30 days for this issue. He took the wheels off, repacked the brakes on one side, but hasn't found the problem. During the test drives the car did not reproduce the noise.

Lately, I've noticed that when I really hear the clunking noise is after I've made a sharp turn, like when driving slowly in a parking lot, and have returned the steering to a straight position. We didn't make any sharp turns during the test drives.

Passat (B5) :: 2002 - Thumping / Knocking Sound From Front End

I just bought an '02 Passat with 42k miles on it. I didn't notice it when I test drove it but now I'm hearing a knocking/thumping sound from the front end that goes to the speed of the wheels at slow speeds (10-30mph). I can also feel it pulse when I use the brakes at slow speeds. What this might be?

Ford - Explorer :: 2002 - Thumping Sound Occasionally When Passing Over Small Bumps In The Road

I recently did a brake job on an 02 Explorer, consisted of new pads and rotors (Rear). The Slide pins were fine and the piston was not frozen in the calipers.

Shortly after the Explorer will occasionally make this "thump...thump....thump..." feeling/sound.

It is not vibration.... it feels more like passing over small bumps in the road.

It is most consistent from 30-50mph, but I have felt it from 20-65.

It is more prominent on decel, but you can feel it on accel as well.

It makes no difference if you touch the brakes or not, or if you push the clutch in and/or take it out of gear.

Speed does not seem to effect the timing of the "thumps" it appears to be the same from 20-60mph. I'm at a loss...

Camry :: 2002 Clunking Sound From Front?

I've been trying to track down this clunking sound, its only really happening when I am going at about 30-40mph speeding up or slowing down in that vicinity..

Its a light clunk clunk sound that seems to be coming from the front left of my car...

It cant be the struts, because I've just put new ones in a few months ago... What could it be? some sort of CV joint or bushing?

Ford - Ranger :: 2002 - Making Clunking Sound

My 2002 Ranger XLT Supercab Edge makes a clunking sound, but not every time, when I start going from a stopped position. It's coming from underneath right behind the cab. The Ford dealership could find nothing wrong. What this could be?

Toyota - Camry :: 2002 - Clunking Sound Near The Front Left Of Car

My 2002 Toyota Camry started making a clunking sound near the front left of the car (and I could barely feel it, too) at low speed over slight bumps. My mechanic, who I trust, said I had two broken engine mounts. He replaced them. Sound continued. He said I needed new struts. He replaced them. Sound continued. Decided to take it to a Toyota dealer. They said I needed new lower control arm bushings but couldn't guarantee that was the source of the sound and they would just have to see. I opted to ask yet another mechanic, who said the control arm bushings are NOT the problem, but he would have to spend some time (could be several hours) exploring to find out what the problem is...at $70+ per hour. The car only has 86,000 miles on it, but I'm getting concerned that I might end up paying for a new car without the new car smell if I keep spending money on "possible" causes.

Ford - Mountaineer :: 2002 - Clunking / Clanging Sound When Going In Forward And Reverse

I have an 02 mercury mountaineer awd. It's making a clunking/clanging sound when going in forward and reverse and it gets louder when turning. Just replaced driver cv axle, changed fluids on front and rear differential also put the stiction modifier in rear. It only does it on the ground assuming it's putting a load on it. Won't do it on a lift. What might be causing it. Tires are same size also.

Accent LC (2000-05) :: Loud Thumping / Clunking Noise Starting Coming From Rear End

I was on the way to the airport in my 2004 Hyundai Accent last night when a loud thumping/clunking noise starting coming from the rear end. At first it sounded like a flat tire or something stuck in the tire so I stopped to inspect but everything looked good. I continued my trip as the noise continued to get louder but made it home. I worked on the car for several hours today and have not had any luck nailing down the cause. The sound appears to be coming from the drivers side rear tire area and would get much quieter when I turned right. It sounds like a spot on the wheel is hitting something but I don't see any area that shows signs of wear. Things I have checked:

- Jacked up back end and spun both tires, both spin with no noise and have no play.
- Removed both rear drums and inspected but all looks good.
- Inspected all rear end suspension bushings but don't see anything that stands out.
- I did notice the strut on the drivers side has some play where the passenger side is tight but when I rock the car up and down I hear nothing.

Civic - Honda :: 2002 - Clunking Sound Heard And Felt On Front Passenger Side Floorboard

My girlfriend's 2002 Honda Civic. Whenever she and I make a turn in it, a clunking sound is heard and felt on the front passenger side in the area of the floorboard, and it seems to come from an area between the seat and the wheel well and seems to be getting slowly but surely/progressively worse/more noticeable as time passes. I checked underneath the car earlier today, and there aren't any observable leaks to report anywhere.

Lexus SC430 :: Thumping Or Clunking Noise Coming From Rear Driver Side Tire

Take a look at the video I recorded with my phone and you can hear a thumping or clunking noise coming from the rear driver side tire. The phone was held upside down sorry!. I'm thinking it's either the brake pads or wheel bearing?

Please try to ignore the wind noises. = Just want some idea so when I take it to a mechanic it would be easier to identify the problem. [URL] ....

Lexus IS 2014+ :: Loud Clunking / Thumping Noise - Dashboard Turns Dark While Car Is In Motion?

I have a 2014 IS 250 F Sport and in less than 500 miles, the car has this "LOUD" clunking/thumping noise coming from the rear when I pass a bump or uneven road. Brought it back to the dealership but the Lexus specialist/technicians said this noise is the characteristic of the vehicle which of course it cannot be a characteristic of the vehicle. This is not the 1st Lexus vehicle I own.

Also, navigation/radio shuts off while the car is in motion? Dashboard just turns dark (completely blackout) while the car is in motion??

Golf/GTI VI :: Thumping Sound Coming From The Front Of Car

In the last few days I have been hearing like a thumping sound coming from the front of my car. It is happening when i going through a turn with some bumps, slightly aggressive, but not crazy. Haven't been in the canyon since it started so I am not sure how it will react pushing the car to about 7/10. Which is about as close to the limit as I will get off track. The sound has come at about say 4/10. just off ramps and stuff. It sounds very similar to a car with very tight coilovers. Could it be the XDS working? It isn't a clicking like a traditional diff, and I don't expect that it is. But obviously I don't have a lot of driving experience with an electronic diff like the XDS. I will take the car to VW as soon as i have time.

Sierra :: 2000 5.3 Sierra Suddenly Overheated In Cold Weather Then Fine

A friend of mine has had this 2000 Sierra since new. It has just over 100K and never had any cooling issues before. Last week when it was about 10 below zero she drove it home and it overheated and pumped a couple quarts of antifreeze overboard.

She refilled it the next day and it was fine but got it looked at by a local independent mechanic. I had told her that it was likely a sticky thermostat and it ought to be changed out anyways due to its age. The mechanic thought I was wrong and that she had driven it off to quickly in the super cold weather.

Windstar :: 2002 - Intermittent Thumping Noise In Engine

My 02 Windstar has developed an intermittent thumping noise in the engine. A bit of history: She has been sitting for a few months because she was throwing a P303 code that I could not track down. Here in IL, you cannot renew your plates until you pass an emissions check, and you cannot pass the check if a code is stored.

Well, I got a warning ticket for expired plates, and I had my daughter's car as alternate transportation while she is in the Peace Corps, so I parked Mr. Breeze, intending to get to her on the weekend. Except for throwing the code and gas mileage being a bit down, she was running fine when I parked her.

Well, life happened, and I never seemed to be able to put the time aside, but now winter is coming and I don't want to subject her ride to the snow, so I made time and replaced the coil, plugs, and wires. But when I started her up, there is an intermittent thumping noise in the engine compartment.

I have double checked the wires, and I think I have them right. As I understand it, the right bank plug wires go on the coil towers 1,2,3. and the left bank wires go on the towers 6,5,4. Is that right?

I made a short video so you could hear it, but it is too big to upload, so here's a YouTube : [URL] .....

Ford Excursion :: 2000 - Thumping Sound While Turning?

My passenger side front wheel is making a thump, thump, thump sound when turning. The wheel is smooth when turning, but when returning to straight it kicks everyone 1/32 of a turn.

I know my sway bar bushings are bad, but I doubt this would be caused from that?

Should I be checking ball joints, hubs? It's been like this for 2-3 weeks

Accord :: 2002 - Thumping Brake Pedal For A Bit / Warped Rotor

I have had a thumping brake pedal for a bit and knew that I had a warped rotor. I suspected the right rear by the wear pattern of the disk. I purchased the parts and started the job to see...what the heck is the cable and assembly on the outside of the caliper? After FINALLY getting the bolts off...not a great placement of this extra assembly...I pretty much had to beat the caliper off the rotor. I was afraid of this...I will have to replace the caliper as it appears to be seized.

Now... what I would assume is the parking brake assembly? I have read some great info on the normal replacement of the pads/rotor...but what do I need to know about the cable and arms? Do I need to release the tension somehow? Does it need to be rigged? Is there a best way to do this?

Corolla / Matrix 2009-13 :: Thumping Sound On Sharp Right Turn

Took my 2010 Corolla in to have it looked at since it has recently developed a clicking/thumping sound when I make a sharp right turn (it's intermittent, but frequent enough to be noticed).

The shop I took it to said the source of the noise was the CV axle, but that after inspection, they didn't see anything really wrong with it, so they recommended simply putting up with the noise to save money, and to keep an eye on it and replace it if/when it actually begins showing signs of significant wear.

Subaru - Impreza :: 2005 - Clicking / Thumping Sound In Front End

My friend has a 2005 Subaru Impreza RS (2.5 L) that just (today) started making what amounts to a clicking or thumping sound once the car reaches about 30 mph. I'm sure it does it at slower speeds, but I was unable to hear it. It is definitely in the front end. And seems to be coming from the drivers side. I asked if she had hit any large potholes recently, and the answer was no. Around three weeks ago she had studded snow tired mounted on the car. I don't think the tires are the issue. But perhaps the installation process may have played a part since the care was placed on a lift.
