Prius (2004-09) :: Front End Rattle / Knock Noises
I have seen a few separate threads regarding a front rattle/knocking noise on some Gen II Prius. This is not the engine mount metallic-knock sound but rather a subtle rattle coming from the front end when going over smallish bumps at low speeds and sometimes accompanied by a slight knock in the steering wheel.

So I have searched about engine rattle/knock and I have found lots of results for cold starts but I haven't found it for the issue that I am having. I have a 2010 and anytime the battery is real low, around 2 bars and the ICE fires up to charge it, any time I give it a little throttle input, I get heavy valve rattling. It doesn't matter if its cold or hot, it does it as long as the battery is low. I never get this noise when battery is charged up, only when low. I have a link to the video below and you can see once I give it some input, it starts to sound like an old diesel tractor. Prius has close to 200K on the odometer and all my maintenance is up to date. Please turn the speakers up but the noise is right at 5 seconds in or so.

View 19 RepliesFord Transmission :: Severe And Sudden Leak Develop In Trans Cooler
I have a 2001 E350 van with the 4R100 Transmission. It had a severe and sudden leak develop in the trans cooler. The driver noted trouble getting the vehicle into gear, into reverse, but ultimately drove it about 25 miles until it stopped unable to go up a hill. Once stopped, the leaking fluid was obvious from smoke & fluid over the back of the vehicle.
It was towed to a local shop (not a transmission shop). They put 9 quarts of fluid in and started the engine hoping to see the transmission functional but only leaking from the cooler. Instead they found it not operational and no fluid coming from the leak. They assume the pump is ruined to the point of not pumping fluid at all.
Is it likely that the front pump is the only damage? Can I pull the unit swap the pump & put it back in service? What else (if more damage is likely) would a transmission repair shop find? What about a used transmission?
Ford F-150 (2004-2008) :: Intermittent Rattle / Knock / Running Rough And Dying At Stops
I am working on a customers 08 F-350 5.4l has 135k on it. came in with a severe rattle/knock, running poorly, and dying at stops. ECM gave up 8 codes relating to the timing... Found the phaser replacement steps here on FTE and followed them and replaced the VCT solenoids since i was in there. Customer reported that he replaced the cam sensors already. Ran great for a day, and the next day when I pulled into the shop it gave me a rattle. Not as violent as before but noticeable. I special ordered the wedge and followed the replacement to a 'T'. I have no performance issues and no codes.

I have a 2005 prius, and it has developed a severe vibration when the engine is running. It is only when the engine is running, even in park. I'm thinking it's the motor mounts, but I was wondering if there could be another cause. I do not have a check engine light, and the engine appears to be running fine. the vibration goes away whenever the engine cuts off, and there are no other drivability issues.

My wife's 04 AWD 2.7 Santa Fe has developed a severe vibration. I have rotated tires, checked ball joints and tie rod ends, and had it aligned. The tires show very even wear and don't appear to have any bulges or broken belts. The vibration is so severe that the vents rattle louder than max radio volume, but it completely disappears in even the gentlest right turn.

This summer, my steering rack failed, and I had it replaced with a remanufacutured steering rack. All went well, until a few weeks ago I started feeling a pulsing effect when turning, usually when turning right. On a few occasions, the shaking has become severe. It is a back-and-forth effect, about three times a second. It is bad enough that it has triggered a power steering error on two occasions. I took it to the garage who installed the rack, asking them to have a look at it, and they found nothing. Because the effect is regular, I am assuming that I am feeling the 12V power assist malfunctioning or reacting to faulty input.

My 2007 Prius has 120,000 miles. I live in a mountainous area. I need to climb 3 miles at 6% grade to get out of my neighborhood. Lately I've been noticing the traction battery loses charge fairly quickly and I've been thinking about replacing the battery. Much of my driving is in steep hills and I run a full charge cycle many times a day, so I guess I should expect some loss of life.
View 7 RepliesHonda - Pilot :: Rattle / Knock In Front End
Our 2003 Honda Pilot with 130K miles recently developed a front end Knock/rattle, which is sustained at about 70 miles per hour. Dealer "couldn't hear the noise". Tried new tires per dealer suggestion- fail! Recently we towed our 2100 lb pop up with it, and it was MUCH louder, and of course sustained at lower speed. Should we even be towing a pop up with a vehicle that has this many miles on it?

I get this noise, AT TIMES, on cold starts which sounds similar to a knock. It lasts for maybe a couple of seconds at most. It's not the FI ticking that is generally always present. I see where other models (engines) have reported start up noise but nothing on the 460.

View 38 RepliesCamry :: 2002 XLE 4-cylinder - Inconsistent Knock / Rattle From Engine Compartment
I own a 2002 Camry XLE 4-cylinder with about 95,000 miles which is in excellent condition and well-maintained. Recently I began to hear a rattle, tapping or knocking sound apparently from the passenger side of the engine compartment (passengers agree with apparent location). It almost sounds like engine knocking, but the times it happens seem to rule that out. It could be some metal vibrating against something, but I can't hear it when I'm under the hood, and nothing appears loose. I've taken it to my trusted independent mechanic, but he couldn't duplicate the sound driving for 15-20 minutes on the freeway or see anything wrong when put on a lift. The sound doesn't occur all the time, of course; that'd be too easy.
The noise begins:
-after I've been driving 15 minutes or more
-after the car gets above 45-50 MPH, but when the noise finally begins, it will then occur down to as low as 30 MPH.
Last weekend I drove 1000 miles roundtrip on the freeway at 65-80 MPH; it didn't begin for 30 minutes, but continued most of the way to my destination (5.5 more hours), though it did seem to stop a few times. This week, my 20 minute drive to work, which has about 10 minutes on the freeway at 65, has not caused the noise to happen once.
Characteristics of the problem:
-the noise is not related to RPM; once it begins, it is about the same frequency and volume at 30 MPH as at 80 MPH
-it doesn't occur when in park or neutral and idling, even if the engine is revved, and even if the noise was just occurring on the freeway moments before
-it doesn't change when running over rough pavement or in turns
-it doesn't change when regular gas is replaced with premium (tried this last week to rule out engine knock, though the lack of RPM affecting it probably ruled that out already).
So it seems like it may be related to the speed of the car and perhaps the temperature of the engine or compartment. The hood latch appears to be holding tight with no play, the strut mounts were replaced 10K ago, and the wheel bearings check out fine.
Camry 2012+ :: 2AR FE Engine Knock / Rattle Noise At Cold Startup
There was a TSB for 2AR engine, Engine Knock/Rattle Noise at Cold Startup. My question is for those I4 camry owner, do you have these rattle sound when you start your vehicle at cold? I am not sure if mines have the same issue, but pretty sure is I can't find any differences between mine and this clip:

So should I take it to the dealer? Or it's normal?

Ford - Aviator :: Rattle / Knock Noise Coming From Top Side Of Transmission
I have a high mileage Aviator - it currently has 162k+ ... I have owned it since 136k, and according to Lincoln's records the transmission was rebuilt/replaced shortly before that ... The truck has run well since we've owned it.
It has developed a noise that I originally thought was an engine problem (bottom end), but I got under it today and took a good listen and it sounds to me like it's coming from the top side of the transmission.
I recorded some sound: 4.6L dohc "rattle" from above transmission - YouTube .....
Ford F-150 - 1997-2003 :: Rattle Under Load / Hard Knock In The Bottom End
I've got a 97 truck, broke the crank, swapped in a motor from an 07. Heads down is 07, intake up is 97. had heads planed and a valve job with new seals done. Left it alone from the rings down. Got it in this weekend, running today. Ran it in the driveway with no load for about 30 minutes, top end was noisy for about 5 minutes till the top end got good and oily (I'm assuming). Purred like a kitten, sounded real smooth. Took it for a drive around the block, heard the clatter in the video below. It's almost always there when driving. Brought it back, turned it off to check oil, it was a quart low. Added oil, startup was VERY labored with a real hard knock in the bottom end. Ran like poo till I gave it some throttle for a couple seconds, then it cleaned up and idled well. Let it run for a couple minutes, turned off and let it sit for a couple minutes then started back up, same thing. Very labored with hard knocking.
