Ford - Focus :: Lurch Forward Before Stopping / Grinding Noise And Loud Vibration
Mar 25, 2013
So I just bought a 2004 Ford Focus. I did not drive above 15mph when I tested the car due to the lake effect snow that was occuring. Now that I own the car I have noticed if you try to stop going over 20mph the car starts to stop but last second it lurches forward a little bit. There is also a grinding noise that sounds like its coming from the back and a loud vibration that sounds like its coming from underneath the middle of the car. I'm trying to figure out if it is the brakes, tires or a leak in a brake line (those are all things my dad said it might be).

When coasting to a stop, I have noticed when the rpms reach 1000-1100 they jump up a little bit. Sometimes you can even feel the car lurch forward just a tiny bit. Is this normal for a car downshifting??

I've had a grinding noise coming from the front passenger side, sounds like the wheel area of the car, for many months. I've driven thousands of miles on it like this, mostly because I'm broke and the car otherwise runs fine, but also because when I've taken it to mechanics, they are stumped.
I took it to a shop about a year ago and he had it for a week, had different specialists look at it and ruled out anything mechanical (wheel bearing, etc.) In the end, he threw up his hands and didn't want to give me any more free labor for his non-diagnosis, and thought he ruled out everything but the transmission. I took it to a transmission shop recently, and the guy ruled out right away that it was the transmission. He tried to diagnose the problem and was stumped too.
Here's what it is doing. It makes a grinding noise around the front passenger wheel when I accelerate. Only when I accelerate. It seems to be more active when it is cold, and after I've been driving the car for about an hour or so, it goes away. It used to only really happen when taking right-hand turns, and that is still when it is at its worst, but now it does it anytime. However--some days it is very bad and some days very light. One day--of course the day I designated to take it to the shop--it stopped altogether and drove like new. Just until I got it home. It is worse in low gears, and used to only happen in first, second and third, but now on an active day I can hear it on the interstate in fifth gear.
The shops I've taken it to can't seem to figure out what it is. Reading threads online, I've learned that people with similar problems found the problem was a bad passenger side motor mount. I have the car at a new shop right now, and I asked them to replace the motor mount, even though it looks fine. I had a long talk with the mechanic there today and he seemed a bit skeptical, but thought it was a possible solution.
Should I spend the money on a motor mount even if it looks okay? (I've also read that the Focus mounts look fine from the exterior when they are bad because they have a gel interior that busts). Especially if this doesn't work, I'm going to be back at square... um, zero.

There's a loud grinding noise from the front end of car when I turn the steering wheel... even when the car is off and in park.I can post videos of the noise if needed.

Twice today with cooling temps (45 during the day, closer to 30s on way home) while shutting down after being put in park my Prius did the "lurch forward and shudder." This is something new! Fuel has been purchased consistently from the same Shell station, she's garaged at night and MPGs are averaging 45... OK but nowhere near my great warm weather mileage. We are at close to 2200 on the odometer if my memory is working right - 2012 4 version. Happened once at the bank after work, once in the garage, level ground.
Not sure what is going on... this is new to me with a new car....

PROBLEM: grinding noise in left front when slowing and stopping.
Starts as a howling noise, turns into a grinding as you brake and come to a stop. I feel it in the pedal and as it slows it feels like metal to metal brakes
WHAT HAVE WE DONE: Replaced both front hub assemblies (MOOG)... Replaced dust shields, rotors, calipers, pads as well as all new brake hardware.
At any speed when I brake hard it grinds and howls, I have taken out the 4x4 locking hub assembly and it does not change the situation. I am stumped!

i have with my Treg. Occasionally, like once every two weeks, when I am slowing down to almost a standstill, i suddenly hear a loudish grinding noise that seems like it was triggered electronically. I seem to think it happens when the auto box is shifting from 2nd to 1st before the car comes to a standstill, but not every time. Obviously when I took it to the dealer it did not happen!

I have a brand new 2010 Passat. I am unable to achieve a smooth start from stops and the car will lurch forward when I take my foot off the brake. Any small input from the gas pedal produces a jumpy start to the acceleration process. I have about 300 miles on the car. I bought this for my wife and she is very uneasy about driving it.

Intermittent problem, noticed mostly at low speeds, where car will buck or lurch forward. Most noticeable when accelerating after a slowdown, i.e. applying gas after coasting. No check engine lights, oil & transmission fluid is full. Car has 105K miles, tranny & coolant flushed every 30K, oil changed every 3K, tuneup w/plugs& wires @ approx. 93K, timing belt @ 70k. This car is a gem, mostly driven on the highway that has been perfect until now. Things I've considered doing: replacing timing belt, transmission solenoid, computer sensor that controls tranny. My suspicion is its tranny related but maybe not. Is there a way to check/set the timing on this car? I remember years ago using a timing light on my chevy. This is weird, it will run perfect smooth in the morning and rough with lurching in the afternoon. Could be a total coincidence but it seems to run ok when its cool and not so when it is hotter.

I have a 2005 F-250 4x4 and recently i noticed a grinding noise while driving and then when I come to a stop I hear a clunk and the grinding stops. It sounded like it came from the driver side wheel so I changed the wheel bearing assembly. About 3 days later it started again. Now it sounds like it's coming from both sides. I am at a loss. The hubs are unlocked. It's hard to describe the sound but to me it sounds like 2 gears with a large chain rotating on them. I hope that made sense. The clunk can be felt in the brake pedal.

My car makes a grinding/popping noise when driving that worsens when I go over bumps and that completely stops if I even touch the brakes. When I accelerate, the noise speeds up as well. I took it to a mechanic about three months ago and he said it was a loose bumper and that he secured it. After leaving, the noise got louder and happened more often. Sometimes the noise doesn't happen, while other times it does. My dad changed my front brake pads about a month ago so it can't be those. Is it possible that it is still my bumper making the noise? If so, I don't understand why it would stop when I brake.

I have a 2000 Ford Focus with about 145,000 miles on it. When I'm driving I can hear a drumming noise. The faster I go the louder and more fast paced the drumming noise becomes. When I hit about 50 I can hear it, and the faster I go the louder it is. At about 60 the car starts to shake a little bit. When I'm going like 20 or 30 or so, it sounds like I can almost hear my tires turning if that makes sense. The noise is really loud and is starting to concern me. A friend said my CV boots are ripped, but before I take it into a mechanic I would like some non biased opinions.

I have the not-so-uncommon grinding brakes problem too. In my case, however, there is a scarier difference: if I have to stop suddenly and hit the brakes hard, I hear the grinding and the car kind of shakes, but then as the car is decelerating, I will actually get the feeling that the brakes have totally disengaged, and the car will lurch forward! If I then depress the brakes quickly, they will engage again and stop the car. I've had a couple of close calls in heavy traffic when cars in front of me have stopped suddenly.
I guess that the grinding might be the ABS, but I've never heard of ABS causing your brakes to konk out completely! It's to the point where I'm scared to drive the car if I know there's going to be much traffic. I bought this Elantra last October to have a nice new car to drive my 6 and 4 year old around, so I'm very unimpressed, and scared, with the whole situation.

I hear a grinding noise from tire area when in motion and when stopping and happens only intermittently. I have taken my 06 chevy uplander to 2 auto repair shops and to a chevy dealership repair shop now and all three say they can't find anything wrong with it. shortly after, the noise happened again but now when it occurs the display screen reads... Service ABS system and service Traction system... when i turn the engine off and back on again the warning is no longer there unless the noise occurs then will read both again.

I installed a set of Brake Performance rotors ( slotted ) with premium ceramic pads and have had a bit of strange stuff going on from day one. When I first got them installed there would be a mild grinding or rough feeling when stopping. It got better over the first couple of day but was still there. I also notice a loud whirling or humming noise when I stop from high speeds. I called brake performance and they saids that it may be that the ceramic pad is to hard for the system. It sounded a little odd. The weather in AZ finally hit 77 yesterday so I have been driving with the windows down and have been noticing more of the grinding sound even when the brakes are not pressed.

Ive got a 04 f350 that after u shift into 4hi or 4lo when u accelerate it it makes loud clunk noise in fwd or reverse hi or lo. With hubs unlocked it still clunks. Have checked, wheel bearings, axle U-joints, and driveshaft joints all good. So I am thinking I've got issues in t-case. Popped drain plug out and wow that dex merc 4 looks nasty. So thinking I need exploded view of transfer case.

Chasing down a grinding noise. I have done a lot of research but nothing quit matches up with what I am hearing.
I have a 1979 F250 4x4. A few days ago I put the truck in reverse and as I was backing up it was like the drivetrain locked up. After that I put the truck in gear and started on my way. As I got up in speed a pretty loud grinding noise was coming from the tranny. 2nd and 3rd gear aren't bad but when I get up to 40+mph it sounds like crap. If I push in the clutch the grinding is still there. While driving I also put the transfer case in neutral, kept the tranny in gear, pushed in the clutch and the grinding stopped.
I also took the lid off, inspected the forks and thoroughly cleaned the inside but noise still continues.

Bought a 02 Ranger, 4.0 4x4 super cab 122,000 miles. etc Picked it up for 500 bucks because someone scrapped it along the side of a guardrail this last winter. Replaced rack and Pinion (cracked), Tie rods, Shocks, driver side knuckle and wheel bearing, and some body issues (bed is still shot so if any black short bed sitting around let me know). I've been kind of putting around all day in it, letting it used to working again. Starts right up, turns easily, I string aligned it so it goes where I want.
But as I get up to speed start at about 10MPG there is a vibration based noise coming from the front, can't pin down if its left or right. If Im going straight then turn it gets slightly more intense as I even start turning the steering wheel. The noise increases with vehicle speed. And I don't know if its separate or related, but any turn over 5-10* to the left results in a grinding sound but then I turn to about 10-15 and it gets less intense. No noise turning right.
I'm thinking a bad CV, TWO bad CVs, or a bad differential. Before I start ripping into those things, thought I'd get opinions, or hopefully experience in this area. I'm really hoping its something small and stupid. (like not getting a professional alignment)

Today I was out getting lunch in my Ecoboost When it started making an extremely loud grinding noise from the front end of the truck. My first thought was I blew a turbo. After holding the break and building boost I discovered it was not the source of the noise. Also the truck runs perfect and there is no smoke. I then took it to my friends auto shop and pulled both front tires off to check and see if anything break related came loose. We found nothing. The noise only happens upon acceleration or cruising throttle, as soon as you let off the sound goes away. So after I found nothing I took it to ford and what would cause that, but they assured me that they would have my truck for a long time while they figure out the issue.

What the fix is for my 2007 Mercury Montego Premier? When the car is in drive and the car is either stopped or at a slow speed such as at a stop light or pulling into a parking space, the car lurches forward. It is almost as if the computer is telling the car to step on the gas. I am concerned for my 16 year old daughter to be driving the car and have the car suddenly accelerate and get into a collision.
