Prius (2004-09) :: Knocking Noise Coming From Passenger Wheel Area?
Mar 10, 2014
We have an 07 Prius with around 150,000 miles on it.
A couple of weeks ago I noticed a slight knocking noise coming from the passenger front wheel area mainly when I was turning toward the right.
Question.......So when turning to the right, it first seemed to me that the right side would experience a heavier load. However, after further thought and applying some physics the inertia of the car would actually be putting a heavier load on the left side during a right turn. Which is correct?
Just trying to troubleshoot the noise/problem.
#1 when I apply the brakes, the noise doesn't change. I don't think it's brake related.
#2 the noise speeds up with speed, meaning that it's rotational.
#3 The noise does get louder when I am turning right but has know progressed into a constant noise going straight. During a left turn it subsided.
#4 I did take my floor jake and jaked the pass. front wheel up but didn't see anything broken or damaged. I couldn't rotate the tire though.
#5 I also had the tires rotated today and the noise got worse.

Just picked up my BMP R32 last week. The car is MINT, only 25k on her, seriously probably one of the cleanest, stock mkiv r32's left. I got every single service record since brand new, all done by a Volkswagen dealer.
Only problem is, a knocking noise has just started to develop, coming from the front passenger area somewhere. It is only noticeable when I brake or let off the gas after accelerating, but definitely more noticeable when braking. At first I thought it was something rolling around in the door, but now it seems clearly suspension related, or a loose bolt or something?

2016 LTD Ultimate, 2700 miles. First and only Hyundai for the moment.
I've experience this one twice, a few weeks apart: cold start the car, and in the first 100 yards or so I'll hear a tapping noise that's clearly rotational, varies with speed but eventually ceases. Sounds like it's coming from front passenger wheel well area, and sounds like a stick or some sort of debris is stuck in the wheel. Both times I've inspected the area and found nothing whatsoever.
I live in an apartment complex area, park in a lot always in reverse so I'm always going from park to drive. The area I live in is wooded ("Pine Barrens" region of Long Island) but the roads are paved so it's not like I'm driving thru wilderness.

I recently started getting a light tapping noise coming from the front passenger side tire wheel area. It almost sound like a nail stuck in the tire, but lighter in sound and there is nothing stuck in the tire........
Here's the kicker: It only happens when I turn LEFT!!!! I checked and there is nothing obvious that sticks out to touch the tire when it turns...

I've owned a 2012 Prius Two for less than a month now, and today while driving home I noticed what sounds like road/wind noise coming from the rear passenger side area. Googling about this revealed information about the battery fan. However, I'm unsure if what I'm hearing is the battery fan or road/wind noise that I just haven't heard before.
Here's information regarding the conditions I was driving in:
- 84 degrees outside temperature
- car had been sitting in an open-air parking lot for about 2 hours
- no tint, no windows cracked for hot air release
- upon returning to the car I turned on the AC to 68, set at mid range speed
- was driving on the interstate doing some stop-and-go, but mostly 50-plus MPH
- windows rolled up completely, no doors ajar
- it sounded like air rushing by
- could not hear anything coming from the left rear side, but my left ear is partially blocked by the headrest, so...
- sound would decrease in volume if car slowed down
- sound would increase in volume as car got faster, but would eventually level out it seemed
- sound would completely go away at speeds below 20ish mph
- sound would not change based on level of AC, whether on, low, high or off
- checked battery vent for obstructions/debris, saw nothing, and was cool to the touch
- car has about 28k miles on it, replaced rear tires yesterday but all bolts, caps, etc. are securely in place

Having issue with his truck. He bought it 3 months ago and has no history. 166k. You now know as much as I do about the truck! He knows little about automobiles so fact finding has been difficult. I have done all my own work on countless US and foreign automobiles over the last 30 years and never take my vehicles anywhere. I will try to post as much detailed info as I can. I have read tons of posts now on various forums so I am up to speed on VCT and phasers.
This one seems similar, but not exactly the same symptoms which is why I am here. I have already pulled the VCTs and found the passenger side missing the top screen. I swapped them from side to side which made no difference. I checked ohms and they were at 15 which is normal from what I read. They were very clean and moved easily when I took them out so they were not gunked up so I don't think that's the problem. It idles very smoothly and isn't rough at all.
I have posted a video of the knocking/dieseling noise (link below) coming from the passenger side. The knocking starts as soon as the truck is started hot or cold (outside temps right now 70F-90F Houston). I can make the knock disappear by gently depressing the gas pedal going from idle of about 650/700 to maybe 750/800 and it will go away completely as long as I keep it gently depressed. As soon as I lift up it returns.
If I rev it up to 2000-3000 rpm it does not knock, however, as soon as I lift off quickly, it seems to knock at a high speed, hangs for a second and then knocks all the way back to idle. However, if I rev up and then lift off very slowly, it will not knock. I have tried to locate the exact location of the knock, but doesn't exactly seem right at the phaser, but actually back around the 2nd and 3rd spark plug area, but I can't tell exactly. I've had a couple people tell me the same when I asked them to tell me where its coming from. The noise is bouncing around in there so difficult to pinpoint exact area.

I wanted to get some second opinions on what this could be so I know where to go next.

I have a 1999 Jeep Grand Cherokee that, upon starting in the morning, has a knocking noise coming from the front passenger-side wheel area. It only knocks when the car starts moving, and stops once I get up to 15-20 miles per hour. It ONLY does this when the car is cold. The noise does not occur throughout the day, only when I start it each morning. Is it something to do with the wheel bearing, but that does not seem to be the case.???

Just had my 40k service done, and also got an alignment done at the same time. On my way back from the dealer I noticed a knocking noise coming from the lower rear area of the car which is more noticeable when going over bumps. Its intermittent. Thinking something got messed up when they were doing the alignment? What this might be?

I just bought a 09 Corolla S a month ago. In the last few days I've been hearing a popping/knocking noise while I'm driving. It sounds like it is coming from one of the wheels but which one. It usually happens once I decelerate or driving at low speeds. If I brake the noise will stop. The rhythm of the noise doesn't seem to be consistent with speed I'm driving. It happens more often on bumpy roads but it still happens on smooth roads. I'm wondering what are the possible problems that are could cause this?
I don't know if this would relate to the sounds I mentioned but when I bought this car it had brake problems. It would grind pretty loud. The dealership ended up replacing new rear drums. So when I drove it home everything sounded good for about a week. The grinding noise came back and after I sprayed some brake cleaner it went away for a few days. I'm assuming thats what the dealership did to hide the noise. I went ahead and changed the front pads and that worked for a week or so...but the grinding noise is back. I was about to change my rotors this weekend when the popping/knocking sound I mentioned above started happening.

My 1999 jeep grand Cherokee with 170000 miles with a straight line 6 cilinder has a knocking noise coming from the valve cover area. It is only present during a cold start and for about 2 to 3 minutes. Once it starts getting hot it stops. The engine runs fine it has lots of power and I do not have any other issues.

I purchased a 2010 Escape Hybrid last October. Within a month it would occasionally make knocking noises from the speaker area above the right side (passenger) rear wheel well. It took several visits to the dealer before this noise would "perform" for them. They thought it was the amplifier, so they disconnected the amplifier...it still did it. So they replaced the amplifier ... it still did it, but it changed pitch and frequency.
I have made videos of it for them since it is so erratic it is hard to get it to do it for them. It will go days, weeks or even months without doing it, and then do it consistently for days and weeks. It seems to do it most when the weather is around 40-60 degrees and often when it is damp ... although this is not always the case. It will do it after you turn the car off for up to 30 seconds ... It will do it when you first start the car before you move.
By the way ... my son in law swears it is the little circular thing in the center of a speaker that vibrates back and forth with sound that is "popping". I suggested that to the dealer and they said that would be really surprising ... I told them that whatever it is its going to be surprising!

It's a 2006 hyundai sonata LX.
Now Is it anything I should worry about? Car has 72000 on it. Always used synthetic Mobil 1 5w 30.
This is on a completely cold start up, 30 degrees outside. Only makes the noise until car warms up. Anything I can do to prevent this? Or is it not something to worry about? Should I just let the car warm up a little before I drive it?

...... 2010 Corolla LE 1.8L ...... View the video I uploaded ....... The noise is seems to be getting worse. My first thought is the bearings in the water pump may have failed. I'm also thinking that there isn't adequate lubrication near the gear assembly or the belt. Could there be a problem with the tension in the belt?

I have a 2005 Jeep Wrangler Sport with a six-speed manual trans and an in-line 4.0 6-cyl engine. I discovered a month or so ago a strange rattling sound coming from, what sounded like, the front passenger wheel area. It would occur when I slowed down to 10mph or slower or when coming to a complete stop, or when starting out from a stop, until surpassing the 10-12mph mark. The rattle is audible both inside and outside the vehicle. It's a low-pitched sound like an "aaaaaahhhh" you make when opening wide for the doctor to look down your throat, only with a metallic rattle thrown in. Best way I know to describe it is a voice saying "aaaaahhhhh" through the back of a fan.
I recently discovered, when I took it in for an oil change and tire rotation, that my front tires were wearing much faster than the backs and had a very noticeable "choppiness" to the tread. I have since installed new shock absorbers on both sides of the front suspension in hopes that would even the ride out for the front and eliminate the choppy tire wear. I originally thought that the tire wear and the rattle were related, but I took it to a mechanic who raised the front end and hand-spun both front tires and they made no audible sounds while spinning.
The mechanic said he believes that the rattle is coming from the front differential. Now, I am no pro mechanic, but I am not afraid to tackle a car repair job as long as I know I have the tools I need at hand to properly complete the job. First of all, does the differential sound like a good place to look? There's no change in the rattle when applying or releasing the clutch and it shifts smoothly, so I am pretty certain it's not in the transmission. Is the differential something that I could remove the cover and adequately diagnose a problem on my own? Just don't have funds available for a large car repair bill, so I am looking at trying to tackle the issue myself.

I owned a 99 f250 a little while ago. Just bought a 2006 crewcab F150 xlt about 2 months ago, and for the past month there has been this unusual grinding or whirring like noise coming from the front passenger side wheel.
I took it to the mechanic and he found a bad wheel bearing on drivers side and replaced it but that wasn't the issue. He could hear the noise but wasn't able to figure out what the actual issue was.
The noise only happens when my foot is on the throttle. (not when coasting) and i also just discovered that it doesn't make any noise at all when put in 4x4.

I have an 04 WRX, I've upgraded the suspension (1.5" - 1.75" drop front and back respectfully) and have a full set up of strut tower braces. Recently when accelerating from a stop, I get a clicking noise from the passenger front wheel area, I hear it all the way through first, second, and most of third...the sound is probably present after that but my exhaust drowns it out. My first choice of problem is that the CVs have gone, the car has 140k on it...

I just picked up a 2001 F350 with the 5.4L with 200k miles. When I test drove the thing the engine sounded fine. I got it home and noticed that it occasionally has a loud knocking noise that is coming from the Left Valve cover area. It sounds like an old Chevy 6.5L Diesel ...
It comes and goes, Hot or Cold. It seems like it usually goes away when driving with RPMs above 1500 or so, however I took off with it yesterday and the noise would not go away, it seems like it might be low on power when the noise comes on, but then again it always feels low on power, so who knows.
I have changed the plugs, oil, and verified there are no exhaust leaks at the manifolds.
Here is a video of the noise: YouTube....
I dont think it is the timing chain, as it seems like its coming more from the center of the cover, when placing my hand on the cover near the timing set there is no vibration or anything that would lead me to believe its the chain.
All of my searching so far turns up 3V stuff, and little info on the 2V engines. The valve cover looks like a nightmare to get off, who have to work on these things (including me).

I have a 2011 E Sedan and recently started hearing a loud grating noise from the passenger front wheel area. It only happens when turning the wheel to the left. It isn't a popping noise like the traditional CV Joint and the boot is still intact.
I jacked the front up today and put it on jack stands. I pulled the tire, caliper, caliper mounting bracket, and rotor to look at the dust shield and there was no sign of it rubbing, nor was there any other wear marks. With everything still disassembled, I turned the wheel hub with my hands and noticed the same, though fainter, sound. I started the car and put it in drive and once again the same noise was coming from the hub assembly area, although I didn't use a stethoscope to listen.
The noise is more profound when under load turning left, but it still seems to coming from the same area. My plan is to replace the entire wheel hub assembly since they aren't that expensive. That, and I don't want to go through the headache of puling everything apart to simply replace the bearings.

It just started and it it only does it at speeds over 40 miles or so. It comes on all of a sudden when driving sometimes. It gets a little louder when coming off the throttle as well.

Tonight I went out to get something out of my car, I had not driven the car in about 5 hrs. As I opened the back driver side door, I noticed a noise coming from the wheel well area. It was a quiet noise almost like a very quiet motor running, but it was very prevalent. I went to the passenger side back wheel and could hear it there also. I've never heard anything like this. Opened the trunk and listened for the noise but could not hear it there. After a few mins, I started the car and let it run, then shut it off and the noise disappeared. Only thing I could think of was a fuel pump malfunction?? I honestly don't know.
