Prius C :: Clanks Coming From Front Brakes When Passing Over Pavement Imperfections
Apr 16, 2013
I have owned a C for almost 8 months. Happy owner except for clanks that seem to come from front brakes when passing over bots dots or pavement imperfections. It has been that way since day 1.
I'm aware a TSB exists for Gen 3 Prius brakes but seems there is nothing for C nor any comment found in Priuschat from other C owners. I would wait the next scheduled maintenance unless it is a serious issue

My 20K R I now generating noises when transvering small pavement imperfections, like cracks filled with tar that are not there with my other cars. It is pretty noticeable almost vibrations through the body and wheel. Only mod I hav done that would effect that is the lower E34 dogbone. It feels like strut bushings, but hard to fathom that at 20K. It is like the rubber isolator from the wheels are gone.

Since Ive got my 2010 Tiguan 2.0 TSI, I hear a creaking noise coming from the front right suspension when riding over uneven pavement. The dealer said it is a common known problem from many Tiguans caused by the engine mount and that VW recommends the change of that part.
The new engine mount is slightly different from the one that is installed in my car. I am still waiting for the part to arrive and to be changed. Meanwhile, I spoke with another 2010 Tiguan owner, here in Brazil, whose car has already received the new part.
He said that the creaking noise has gone but now he feels more vibration coming from the engine and a kind of "diesel-engine-sound" when accelerating... Location of the engine mount: [URL] ....
The "old" engine mount bears the code:
5N0 199 262 G
5AY CN

The "new" engine mount bears the code:
5N0 199 262 E
5AY CN
M082
09/03/10
[URL] ....
I assume that the first number is the part number, the last is the manufacturing date and the others are either car model or manufacturer code or anything else. Note that the part number is the same, except by the letter suffix: "G" in the "old" one and "E" in the "new" part. Well, the suffix designation does not make sense for an evolutionary design...
My questions are:
1) Is it a new design or is it a roll back to an older part that does not cause that problem although it was probably modified due to another issue?
2) Is this part number specific for 2.0 TSI engine or is it the same for other engines (petrol/diesel)?
3) Which engine mount have you got on your cars?

Was talking to a cab company running over a hundred Prius, they like the gas mileage.
Biggest problem running a hundred plus Prius in LA is the skirt front bumper is so low to the ground (for better aerodynamics) ... less than 5 inches ground clearance when loaded ... it hits the ground and bows the side moldings of the bumper.

My wife told me she was hearing a squeaking sound coming from the front end of our 2006 Prius (90,000 miles) along with a noise when she applied the brakes.

Just got a 2013 IS-F. Loving this car, but discovered an annoying issue. Grinding noise coming from front brakes when slowly coming to a stop below 5 mph. Is this normal?

I have a 2002 BMW 525i with 100k miles. Since I bought it at 30,000 miles there has been a braking problem. If I am applying the brakes and hit a bump or rough pavement, the brakes start to "pulse", they make a "rattley, clattering" kind of sound, and it feels as though they will fail to stop the car. Removing my foot from the brake for a breif moment then reapplying the brake past the bump or rough pavement stops this from happening. Most mechanics claim they can't reproduce it, but I can. At about 50K miles I decided to self diagnosis the problem as a bad sensor or "motor" for the antilocking system. I had it replaced which appeared to resolve the issue for a while. But it is now back. What this may be?

Driving home from work yesterday, dry roads, truck unloaded, running around 50mph, had a dog almost run out in front of me. I hit the brakes hard and came to a stop. But, I noticed that my brakes did not lock up the tires. This was a bit of a surprise. My former 2003 Cummins would easily lock them up. Is my truck an anomaly? Can lock up your tires during a hard/panic stop?

I really enjoy my 2009 Smart car, excellent gas mileage, fun to drive too. The only drawback is all the dust coming off the front disc brakes that makes my front wheels look filthy even when the rest of the car is clean. Are there other brake pads that work as good as the factory originals yet don't give off so much dust?

So, fresh off the new brake actuator pump and new hybrid battery and a nice four hour drive yesterday and today i went over a small bump and started to get a loud clunk/rattle coming from the driver's side front wheel area.
It got worse as I drove home and even rattles going straight on a fairly flat road when i hit only minor imperfections. It sounds like something is loose. I cannot reproduce any noise bouncing the car or rocking it side to side.
Prior to this I would get a squeak/groan from the driver's side when I would go over speed bumps and similar large dips or rises, but that has been curiously quiet for awhile.

Had the front end axle replaced due to a boot that was ripped on the CV joint. Three months later the front end is vibrating while increasing speed and passing. The shop is telling me its my transmission?! Doesn't sound right to me. So i take it to another shop and they say its the axle. Okay its under warrenty but the other shop says its the transmission.

I am experiencing an annoying noise from the front struts when passing over bumps. I do not believe that the front end is bottoming, but it seems to give a deep thud sound. It is not a tin sound, but more like something loose and insulated. What is a jounce bushing? Are these something in the strut assembly and susceptible to getting loose? I have read about the springs could be the culprit, but could it be that the front spring is bottoming and the strut is hitting a bottoming rubber ? Jounce bushing?

Swapped for Warn standard hubs a few months back when the ESOF's turned out to be trashed.
Since then, I've noticed a rattle coming from the hubs when driving over rough or broken pavement. I've checked the outer caps and they're good and snug, proper amount of grease inside, and the hub itself is completely secure.
Do aftermarket hubs have tis issue? It's not critical, but on cooler evenings with the windows down it sound like a rattle trap unless the roads are in good shape. More of a pet peeve I suppose, but still curious.

My 1997 cavalier convertible left side front bounces like crazy on bumps and uneven pavement. Installed new strut, and a new tire and balanced. Still does same thing. Rides great on smooth road. All suspension bushings look good and there is no play anywhere.

When braking from very low speed to full stop (f.e. parking maneuvers), i often hear a loud "pop" coming from the front brakes, regardless of steering direction. I'm pretty sure this has been discussed before here but can't find a thread.
Brakes are otherwise working good (front & rear) but it's time to do a maintenance just to be safe.

At 202,000 miles, my 2002 Saab 95 engine went out -- the motor clanks and spews clouds of smoke. I want to replace the motor with a CarFax verified low mileage engine because I plan to keep the car for a few more years and give it to my son. My mechanic will charge around $900. But the engine prices vary on miles, of course. The lower mileage has higher prices, etc.

I have a 2002 accord 4-cyl with a 5-speed with 89,xxx miles. Just a few months ago, I noticed a clunking sound coming from the front suspension when I go over certain bumps. "Certain" bumps are usually wavy pavement or dips (not wide dips, but short/concise ones), and sometimes certain speed bumps. Sometimes the sound happens regardless of the types of bumps though, but the aforementioned ones usually bring the noise quite consistently. The sound hasn't really gotten worse, but it hasn't been getting better either.
A while back when I had my timing belt done, the mechanic stated that one (or more) of my engine mounts were worn. Is it possible one or more of my engine mounts is the source of this issue (from the engine "rattling" around in the compartment. I'm not sure if that's even possible, just a hypothesis) or is it purely suspension. PS. The sound isn't quite a sharp metal on metal sound. Its more of a "thump" or "clunk" coming from the front end (left or right) as if its bottoming out or a bushing or spacer has worn off. Its just loud enough to drive me crazy, and sometimes I can feel it through the floor.

Yesterday, I went to pick my car up from getting an oil change (full synthetic, Mobil 1 5w-30) and an estimate on brakes. turned out to not be quite as much as i had anticipated. while i was in making an appointment for the brake job, my mechanic and i were joking about how if it's not one thing, its another on VW's. And how the car will be in great shape after i get the brakes fixed/replaced.
So i go outside to drive home. When i start the car, there is this odd squeaking/vibration sound coming from the front of the engine. I immediately shut it down and go get the mechanic. after 30 minutes of muddling over it, we determine that it cannot be determined from just looking at it. so they're going to check it out on wednesday when it goes in for brakes.
A little more info, it is definitely something to do with the serpentine belt, because the sound is definately coming from the drivers side front of the engine. If you listen near the timing belt cover there is no sound so i'm pretty sure its not that. and the car drives fine, besides the weird noises that make it sound like a diesel at idle.
its a 2002 1.8t 5 speed wagon, 143,000 miles. I know 5w-30 mobil 1 is not 502 certified.

Replaced both rear calipers about 4 months ago, both were frozen. A few weeks ago I started getting some bad squeaking from the front brakes. The front calipers seemed fine when I did the rears.
Tonight I had even more fun with the beast. Drove to my sons baseball game and felt an odd "grinding" when braking. *Seems* to be coming from the front. On the way home, the grinding was worse and then the fun really started. Hit the brakes and the wheels started hopping enough to shake the whole friggin' truck. Leaving from a light, you could feel the brakes stick and then release, next stop was more shake n bake.
Not sure where to start on this one.

So, I went in last Monday to do the first oil change thing, and visited with the service mgr. for a while about a couple of issues with my big blue dually. I reminded him about the shimmy in the front end when I hit a crack/seam in the road pavement. Or a bridge abutment.
While it's not the dreaded "death wobble', it does shimmy pretty bad at times. He said in order to claim a warranty on the alignment or tires, I had to prove I've rotated the tires as described in the "little tire book of life". Also, he says you can only make a claim up to 12K miles on alignment issues.

My 2003 windstar SEL needed new brakes and to have the rotors turned... instead I opted to buy new discs and pads online ... To my surprise the new discs were about a 16th of an inch thinner than the old.... I changed discs and pads and was happy for a few days, but now on occasion when coming to a stop the front brakes grind terribly....the next time i stop everything is fine...visa versa...dscs feel true (no pulsing) I DID APPLY BRAKE QUIET TO THE BACKS OF PADS....
