I have a whirling or spinning noise coming from front differential at speeds above 30 mph. The noise stops when I release the accelerator? From what I read maybe the bearings.
View 2 RepliesI recently purchased a 2002 Yukon Denali. I've noticed a whining sound from the front end when I'm at a steady speed. When I take my foot off the pedal, the sound stops. I had it in the dealership and they first thought it was the front drive shaft and replaced it. That didn't work at all, so they then told me it was due to the all wheel drive. What is causing this?
View 12 RepliesOk I have a 2001 Denali AWD 6.0, and when I accelerate it makes a whining noise as if it were low on power steering fluid, well I just replaced the power steering pump today and the ring and pinion with bearings about 1000 miles ago. Still whining, the shop today said it could be transferred case but I doubt that because I had it inspected when the ring and pinion was replaced.
View 14 Replies2004 Denali XL with 78,800 miles. I've had it since July '12, and when I changed the oil immediately after buying it (74,700 miles) it was low and filthy. All the fluids were checked/topped, and I had to rebuild the front drive diff and replace a cracked axle tube shortly thereafter.
Everything has been fine since, except for some coolant spewing out mysteriously every once in a while and slightly more than a qt of ATF just disappearing about a week or two ago.
It was shifting a little jerky so I checked the fluid and found it just barely on the stick. Quite a surprise since I check it every month or so, and I've never seen a drop on the ground.
Should I flush or do the standard filter and partial change? The fluid is pink and clean looking at this time.
I have a 2005 Yukon Denali XL. The low beam headlight on the driver's side will not work. I replaced the bulb. Still won't come on. We had just driven the truck up the Dalton highway (The rough road seen on Ice Road Truckers).The passenger side low beam works fine, and all the other lights work fine.
View 1 RepliesMy 01 Denali is making a slight knock when I turn right or left, and I can feel it just a bit in the steering. To my knowledge nothing has even been replaced. It has 134,000 miles
View 6 RepliesI have an '02 XL Denali 1500. The spare tire carrier was broken (cable had snapped) prior to me buying it. As best I can find, the part number for it is: 15026912. I'm curious if any of the newer designs (such as part# 25974845) would fit. 2 reasons I'm asking,
1) the newer ones supposedly keep the tire from falling on the road if the cable were to break, and
2) they're cheaper than the original part number.
Living where road salt snacks on vehicles for 6 or 7 months out of the year has yielded no luck in finding a functional one by checking with the local salvage yards.
Right now the spare sits in the back, which is fine most of the time, but it takes up a good amount of space when packing for trips.
As the says I have a 1999 Yukon Denali that the Rear Brake and Turn signal on Drivers side are not working. Also brake light on trailer DOES work but not the turn signal on that side.
I tested the Tail light circuit by plugging it into the passenger side and it works so that rules out that. What wires to test under the dash to test the combo / multi switch?
Also the tail lights or park light do work (both top and middle bulb lights up when the vehicle is running) its just brighter filament does not light up when breaks are pressed or turn signal is on.
Firstly the truck in question is a 1994 GMC K1500 5 speed 350TBI.
Ok so I'm not sure what is causing the noise I'm hearing. its a humming that I think is coming from the front differential but I'm not sure, maybe it is the transfer case but it certainly feels like its in the front end and my steering does seem affected while in four wheel drive. It only makes the noise while in four wheel drive.
I have one off size tire on the rear end and I'm not sure if the actual tread circumference is the same between the front and rear tires or if any of this would really cause my four wheel drive to act up. I am planning on putting a new set of matched tires on it soon, so if they are the cause of the problem then that's good news.
My Prius c has always made a high speed whirling noise when braking but now at speeds of 42 to 46 MPH this high speed whirling noise is there and when you are just coasting have a noisy transmission or is this something I should be getting to the dealer with.
EVCT transmission noise ....
I have noticed the last 3 times I hit the brakes really hard above 100 mph ( even 120 mph) I hear a whirling noise coming from either the front brakes or tires. Kind of sounds like when you have really old summer tires on the car and you make a stop on the street . I have heard this on the track the last 2 track days I had. I know my front tires (Michelin PSS) are about 40% worn but are still in pretty good shape.
My rotors are the same that carried me through 6 track days in 10 months and was recently told by the dealership that my front pads need to be replaced sooner than later ( they were installed 10 months ago before all the track work ) and I am assuming the rotors are beat up pretty goo . I will be getting new tires in the next few months and will most likely be replacing pads and rotors at the next scheduled service. The car has 34k on it. Is this normal with Brembos or aggressive brakes?
we've had a bunch of snow this week and I've been driving around with my hubs locked in. today I noticed when I was slowing down to pull into my driveway I could hear a slight squeaking sound(sounded like a squeaky belt) coming from the front.
I verified it was coming from underneath the truck behind the engine compartment so I unlocked the hubs and went for a drive, the sound was gone. I crawled underneath and turned the front driveshaft by hand and I could hear a slight rubbing sound at the back of the pinion. The bearing doesn't have any play in and there are no leaks. What is going on? Could the bearing be starting to fail or could the rubber seal around the pinion have some grit in it causing the noise?
A little less than a month ago my wife's old 1999 Mustang had the tires replaced. Since that time there she has noticed two new sounds:The first is whirling/grinding sound coming from the front right wheel that comes and goes. The second is a low, loud groan that seems to come from the front of the vehicle when the brakes are applied. The groan varies in intensity but seems to always be present when the brakes are applied. The groan is not unfamiliar to anyone that's driven an older car, but it is much louder than I have ever seen on any other car (on the other hand I usually drive a Corolla so it may be normal on a V6 Mustang ).
The first sound seems to have been reduced but not eliminated since I followed the advice in this video below and pushed the plate behind the wheel back a bit with a screwdriver. Now it is only audible when the engine is off and the wheel is spun (in other words, when it is sitting on a jack and the wheel is spun by hand), but it is still there.
I took it into the shop where the tires were purchased and mounted. The good people at the shop did rotate and balance them, but both noises remain.
I looked at the calipers and discs and everything seems in order except (possibly) two things. The discs have rust around the edges not unlike the ones in this photo below and I have no clue if that is normal or a problem. The rust is present on all wheels and only the one makes that noise, so I think that may not be the source of the sound,. On the calipers some substance (paint?) is peeling off, but otherwise they look fine and again the same is true on all the wheels so it seems that is unrelated to the noise. I have not been able to get a look at the pad, so I don't know what condition they are in.
Other information: The serpentine belt was replaced a few days after the new tires were installed. The radiator was flushed at the same as the belt was changed. They also threw in an oil change and all the fluids checked at the same time. The tires are new Michelin Defender size 205 /65 R15 and all 4 tires are new. The engine is a V6 and the transmission is automatic.

I have Michelin Energy Saver AS tires with 17k miles on them. I describe the sound as a light whirling with a slight warbling variation in the noise louder from the passenger seat. I carry 42 psi in the front tires. The wear is only slight and even with no noticeable variation. I believe it is coming from the R front and is noticeable at 25 to 35 mph on smooth blacktop roads. Wind noise makes it less noticeable at higher speeds. I wonder if it could be a wheel bearing on the R front side? The sound can barely be heard in the drivers seat.
View 2 RepliesI would describe the noise as a whirling/vibration sound that can be heard as soon as the gas engine portion of the car kicks in (even in park) but gets louder and more noticeable as the car is in motion, especially at highway speeds (55 - 65mph). Opening the hood and listening to the engine block, the noise is definitely coming from around the area of the silver-covered portion by the driver's-side, which I believe is the hybrid synergy engine. The noise has gotten to the point where I really get bothered by it driving anywhere, and I have to turn up the radio to try to drown out the noise.
View 2 RepliesI have a mystery noise coming from the left front wheel.
I have a 2002 Toyota Camry, 4 cylinder, SE Model, 150,000 miles
It sounds like metal on metal. It only happens at low speeds (less than 20mph). Only happens when I turn the steering wheel right. While I am driving straight, the noise is not there.
Here is what I have changed on my car in the last 3 months:
-New Brake rotors
-New Brake Pads
-New sway bar link
-New sway bar bushing
-New outer tie rod end
-New lower ball joint
More Observations:
-CV joint is not leaking
-Checked the struts for proper movement
-The strut seems properly seated in the bearing plated, nothing broken (under the hood)
-I confirmed that the disc brake shield is not in contact with anything
Am I missing anything? What else could be causing this?
I am considering purchasing a 2004 Chrysler Pacifica. It seems to be in excellent shape except for one thing--it makes a very noticeable creaking noise. The noise is coming from the front end and seems to only appear at very slow speeds (like in parking lots). The seller told me up front about the noise, and explained that it didn't start until he had someone "jerk" him out of a snowdrift in Colorado. He says that was about 4 years ago. He tells me he has had the front end aligned, he has had two motor mounts replaced and has had either the tie rods, or the tie rod ends (I'm not sure which) replaced, but the noise is still there. He claims mechanics can't find anything else wrong with it, and they assure him it is safe to drive.
View 4 RepliesHaving problem with my car (2001 Elantra GT) - over the last month or so it's been occasionally making a very loud (not but consistent) grinding noise coming from the front of the car when decelerating at low speeds. The noise sounds like gears slipping over each other but cuts in and out. It's pretty loud and not a nice noise to hear! Sometimes it makes the noise when I brake firmy but not until I reach lower speeds... mostly it's just when coming to a stop, but it did it once last week when I was pulling very slowly out of a parking spot and not even braking.
As it's become more frequent (going form maybe once a week to several times every car journey) I have started to feel something in the brake pedal also, like there's something kicking it from behind. I took it to a mechanic and had to pay a ton of money to get a broken front left ABS ring replaced (it also had the front right ring replaced in May), and within 2 minutes of driving away from the place the noise was back. Before I spend even more money that I don't have on taking it back for extra diagnosis.
I'm told that this is almost certainly the ABS system that has a fault even though the ABS light never shows except when I start the car, and I've taken the fuses out of the ABS in order to confirm that it is. I haven't heard the noise after a few days of driving with ABS unplugged so I think we can be reasonably sure here. Is there anything that I can check myself or test (I'm not very handy when it comes to cars) or can you tell from this information what it's likely to be? Other things that I've noticed with the car which may or may not be relevant are:
- the warning lights for brakes, ABS and TCS are all lit with the fuses for ABS1 and ABS2 taken out. I take it this is normal for all 3 to illuminate with the fuses out?
- since unplugging the ABS I've noticed a slight metallic squeal from the brakes as if the brakes are worn down. Didn't notice this before I unplugged ABS though it may have been there, not sure.
- sometimes when going over a speed bump or just a minor imperfection in the road I hear a clunk in the front of the car and feel something move in the underside of the car. Happens mostly at lower speeds also, but not if I go over the bump really slowly.
- in the fuse box when I took out the ABS fuses I noticed there was a bit of minor melting/brown burn marks on the top of the connections marked (iirc) ECO3 and ECO4 on the diagram (large white connectors). Is this anything to be concerned about?
- sometimes when I have air coming into the car through the air vents it will become significantly warmer for a few minutes, then slowly go back to normal. Can't think of any circumstance that links the times when this happens (eg. speed, weather etc).
- the oil pan has a leak which is on the list of things to fix when the car works properly.
Over the past few months I'd noticed an intermittent grinding noise coming from my left front wheel at low speeds. I took it in once but it refused to play along so I finally managed to catch it on camera and let the dealership listen to it. They booked me for today, saying it sounded like a wheel bearing (to which I agreed) and I dropped her off around ten, not expecting it to cooperate for the second time.
I got a call from the dealer around 2 PM saying that they were able to duplicate the noise and that when they took the left front wheel off and ran the car on the lift with the rest of the wheels off the ground, the noise went away. Even stranger still, when they put the wheel on the tire balancing machine and spun it, gronch, gronch...gronch, gronch....gronch, gronch. It was coming from inside the wheel! I gave them permission to dismount the tire from the wheel and about ten minutes later I got another call saying they'd found a handful of tiny hard rubber balls inside the mounted wheel/tire assembly that were rolling down the inside of the wheel and causing the grumbling at low speed.
Here's the kicker: they were in all four wheels! The tech even saved them for me so I could take a look and they don't look like anything mass-produced; some are larger than others, some are round and some are oval-shaped but when I dropped one on the glass advisor desk, it made a very clear 'Clink!'.
A while back I posted a thread trying to fix a clicking noise coming from the front end on my F-350 dually when applying the brakes at slow speeds (under 15 mph).
While returning from our camping trip last week the noise is back again. It does not occur after the truck sits overnight or for a few hours. But after driving for 30 minutes or longer the clicking will return when I apply the brakes at slow speeds. I tested the rotor temps with a heat gun and it seems to start when the rotor temps get above 120 degrees F. So I removed the brake pads & calipers, regreased the slide pins, cleaned up the pads and applied some lubricant on the back of the pads. I also bent the pad clips so they would fit snugger/tighter in the slots.
Whatever I did seemed to cure the clicking while driving around this weekend. I made sure I got the front brakes nice and warm - up to 180 degrees or so.
When I did this same procedure a few months ago the clicking went away - but eventually returned.
Should I get some better clips? Replace the sliding pins? Pads? The rotors & pads were replaced this winter & the shop said they and the labor are still under warranty. But if they use the same clips - I'm concerned I'll be back to square one in a month or so.
I'm having 4WD problems with my Yukon, but the dealer keeps telling me there's nothing wrong with it (this has been going on for 2 winters now), which is either code for, "let's wait until it's extended warranty expires, so we don't have to pay for it," or "the computer says nothing is wrong, so that's all we're going to look at." When it's in 4WD, anytime I make a sharp turn or even turn a corner there's a grinding noise in the front, if I try to back up, it will only go as far as one revolution of the tires then stop (I have to take it out of 4WD to backup), eventually the "Service 4WD" light comes on, but apparently nothing gets recorded on the computer. It has 32,000 miles on it.
