Prius (2004-09) :: Severe Knock / Rattle From Trans Axle?
My wife called today on the side of the road with a strange knock/rattle sound from the front (engine/trans/etc) along with an apparent loss of power. (no prior warning signs -- just started) She wisely stopped driving, then called me, and we decided it would be wise to have it towed home.
(Let me take a moment to praise my wife who has always been extraordinarily attentive to the mechanical operation of her vehicles. I've always been the fleet mechanic, and if she has ever experienced anything out of the ordinary, she contacts me immediately. She's not frantic or unreasonable -- in fact she's fiercely independent -- she's simply a conscientious person, and I love that about her.)
So we get the car home and I begin looking into what's going on. Was hoping it would be something simple like a motor mount or exhaust shield... no such luck. Everything externally seems fine.
Honda - 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?
View 2 RepliesVolvo - C70 :: 2003 - Rattle / Knock Coming From Right Front When Drive Over A Bump Or Rough Area
I have a 2003 Volvo C70 that I've owned since 2004. In February, I ordered struts for the front with all the trimmings, (spring seat, strut mount, bump stop, etc) from FCP Euro. The struts were Sachs 553-058, which are supposed to be as good if not better than the original struts. I installed them myself, meticulously following the instructional video FCP publishes on YouTube. Installation went very smoothly. Afterwards, I noticed a rattle/knock coming from the right front when I drove over a bump or rough area.
I took it to a local tire/brake place that I have a good bit of confidence. After driving the car, the guy says, "You gotta bad strut!" Called FCP. They sent me a new strut. I installed it and sent the other back. Sounded a LOT better—for about two weeks. Now I am hearing the sound on both sides. I took it to a very reputable Volvo mechanic, I have used since the warranty expired. He drove it, confirmed the sound was not normal. We put it on the lift and he checked everything on the front suspension and was stumped. He said there was nothing wrong with my installation, no problem with the suspension.
Okay, FCP has an unconditional satisfaction guarantee, so I could replace these with a more expensive strut for say $50 more, but is the problem with the struts? I would hate to have to do this installation again and still have the same problem.

Ford 6.7L Power Stroke Diesel :: 2011 F250 - Knock / Rattle Under Front Passenger Side Floor
I have a 2011 F250 4X4 Supercab 6.7L that has a highly annoying knock/rattle (you can't hear it) under the front passenger side floor. It feels like someone is tapping on the floor beneath your feet any time you hit a bump or when on a rough road.
Its been in at least 5 times in 2 yrs with cab mount adjustments/shims, cab mount replacements and realignment of the exhaust and brackets. The knock has been there since about day one (I assume anyway, I'm rarely on that side of the cab) and have burned up my 36k warranty, although I'm told i'm good because it is pre-existing.
I keep insisting its in the suspension and keep being told they can't find anything. The mechanic indicated that this is a known problem, but Ford has not put out any service bulletins other than to do the cab mounts and suspension. Has anyone had this problem and found the solution?
Prius (2010-12) :: Engine Rattle / Knock When Traction Battery Low
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.

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.
View 5 RepliesFord Excursion :: V10 - Engine Knock / Loud Noises Coming From Under The Hood
The wife drove the Excursion (V10) to work today and it ran normal and didn't have any loud noises coming from under the hood. When she started the engine to return home it immediately started knocking. This is not a ping, but a knock. Not a loud heavy knock, but much louder than a ping. It has a fast frequency, seems too fast to be a rod knocking. The frequency is similar to a valve issue, but the knock seems to be too heavy for lifters. Oil looks good. Just changed out 2 weeks ago. Truck is driven everyday.

Prius (Gen 1) :: Squeaky Noises In Front End On 2001?
My son's 2001 Prius (Gen I) has squeaky noises in the front end. When I had the two front tires replaced yesterday, I asked them to see if they could diagnose the problem and he said he thought it could be the control arm because he had had the same noise in his Toyota Camry and that was what it was.
View 1 RepliesGolf/GTI VI :: 2004 - Single Loud Knock From Front Left Wheel
I own a 2004 VW GTI VR6, with 70k miles. i bought it used (at 40k) from carmax. Ever since I've owned it I have had a problem with a single loud knock sound i can hear from my front left wheel.
it happens in two scenarios1) when i back out of a parking space and start turning my wheel - it's only a single knock (hence i don't think it's the CV, and its been pretty constant for at least 2 years), and happens at about halfway through the steering wheel travel.2) it also happens when i accelerate hard, or decelerate. it's a single knock, or pop, or clunking sound. it almost feels like something is loose, or reseating itself as the car puts pressure on the wheel as i accelerate, and then again once again when the car decelerates.
it's pretty damn loud, and disconcerting... i can feel it in the steering wheel as well. it seems to be louder when the car has not been driven for a few days.
I've taken the car back to carmax several times over the past three years but they have not been able to find the fault. they have replaced my engine mounts twice (in 30k miles that I've had the car), which i also think is a little weird. they have also replaced all the tie rod ends, etc. - all the obvious stuff.
I am at my wit's end here - carmax pretty much think I'm crazy, and my warranty has run out, but i think I've bought a car that was in an accident - i'm expecting my front end to fall apart one day as I'm driving...

View 3 RepliesNoises - Grandam :: 2004 - Crunching Sound From Front Right Tire?
So I got my 2004 Grand Am about 2 months ago and noticed after about a week that the front right tire was low. I put air in it, came back to check it in the morning and it was down again. I had it looked at and was told that the tire was pulling away from the rim because of the rim eroding. He put some bead sealant on it and got rid of the erosion on the rim. Everything was fine. But then about 2 weeks later I started to notice a slight crunch when I went over bumps. Over the past month and a half the sound has gotten progressively worse.
It sounds extra bad when I am making a right turn. My brother put it on a lift, took the tire off, pushing some things around and couldn't figure out the source of the sound. Everyone who drives in the car with me can hear it. Other than that annoying sound the car is beautiful but the sound makes it seem like a junky car and it's not. It doesn't crunch when I break or at high speeds (maybe because I can't hear it). I'd hate to bring it to another mechanic and pay dollars for him to tell me he can't figure out the sound either. The car had it's suspension checked etc.
