F Series :: 2004 - Thumping Noise While Braking
May 17, 2013
I have a 2004 Heritage Model F150 4x4 Manual Transmission V6
It started to make a thumping noise a while back when the brakes were applied hard, sounded like from the front end. I figured it was a warped rotor and/or bad pads or bad caliper bolts, the thumping and pulse seemed like that was what it was.
The front end was a mess. I ended up changing just about everything. CV axles both sides, one piece bearing/hubs, upper control arms, bushings, ball joints, tie rod ends, sway bar links, rotors, pads, calipers, hardware, maybe more things.
It all needed done, so no big deal, however the thumping while breaking is still there, it is getting worse and sounding more metallic. You can feel it in the steering wheel and under your feet. The drive shafts are very, very rusted, but seem to have no play in the u joints. I changed the back rotors, calipers, hardware and emergency brake parts and hardware a couple of years ago, they seem good. Taking it out of gear or pushing in the clutch or not pushing in the clutch seems to make no difference. You can go fast and let off the gas, no noise, you can aggressively downshift, no noise. Hit the brakes and you get a nice thump, thump, thump, like I said now it sounds even slightly metallic and getting worse.
I figure if nothing else before long something bad is going to happen and I will know what it is.

'94 Ranger 4x2. Recent new brakes front and rear, installed by a garage who was also doing my clutch a few months ago. Not long after brake job, slightly detectable 'thump thump thumping' sound during braking. At first I thought possible stuck caliper/warped front rotor, but vibration was not in the steering wheel, and as sound grew increasingly louder, seems to be coming from right rear brakes.
ABS light appeared once, but after adding a small amount of brake fluid to master cylinder, has not reappeared. No other brake related idiot lights, and truck brakes quickly and straight. Pedal could possibly be firmer, however.
Took my rig back to the shop, since brakes were supposedly "guaranteed for six months". Out of business, no forwarding address or phone number!
So I decided to bleed the rear brakes. Haynes manual says bleed RABS valve first, then proceed to rear brake bleeders. Found RABS on rail frame, dust cap still on bleeder, (cap was very dusty and difficult to pop off) looks like shop never removed it or bled it! Had to remove its electrical connector to access the 7/8" bleeder nut with a box wrench.When I tried to bleed it, NOTHING came out. Neither air nor brake fluid. Moved on to rear brake bleeders. Normal. Bled 1/2 pint from each, as I topped off the master cylinder. I have not yet removed either drum to inspect.
Long story short, does the RABS valve on a '94 Ranger rear wheel only ABS need to be plugged in to be able to be bled? Do I need to have the ignition 'ON' while doing so? (I thought only '95 and up needed the Ford factory code reader to bleed four wheel only ABS valve?) And can the thing fail without setting the ABS warning light, and allow the rear brakes to still (noisily) work ?

Have noticed a thumping noise when braking at a Low speed on my 2013 RX 350. Brought it to the attention of my Lexus service mgr at the 5000 mile service. He did a test ride and heard the same thumping sound. He then test drove another 2013 RX at the dealership which made the same noise.

Driving home from work (a 30 minute hwy cruise) I had to stop for a traffic light. As was sitting there I hear a thumping noise from under the hood, otherwise it was running the same as always. Got it home and I didn't hear it anymore, looked under the hood while idling, seen nothing, shut it off. top rad hose had a slight amount of pressure, started it and it quickly built pressure and felt a rhythmic thumping in hose and it got fricking hot quickly. I figure either a head gasket or cracked head.
I just recently did an aggressive cooling system flush using Prestone heavy duty cooling system flush (can only get this at a dealer) because the previous own neglected it, and it blew a head gasket, tons of rust inside when I did it. I'm gonna borrow a tester to check for exhaust gas in the cooling system and what did it end up being? The guy I bought it from (the previous owners mechanic) put 1 or 2 head gaskets on it.

Ok I have a 1998 Ford Ranger XLT 4.0L automatic 4X4 with A/C my problem is i just had the timing chain,water pump, thermostat, upper and lower hoses, and front crank seal replaced. I got it back and right away noticed a thumping noise at idle only... My gauge was always steady at the same spot it had always been. but the thumping was loud when idling. Now the sound seems to have moved farther towards the engine instead of the dash and tonight when i popped the hood noticed the top hose was collapsed and i could feel no pressure. the thumping noise seems to be coming from the area of the thermostat. I have no oil in the coolant and no coolant in my oil! I tried to get the air bubble or pocket out if thats what is the problem by running the engine till hot with the radiator cap off but it made just a huge mess. it did seem to push a huge air pocket out but still does the loud thumping. This all started the day i got it back from the mechanic so I am assuming its an air pocket. I planned on changing the thermostat tomorrow.

When accelerating and/or braking, a thumping or knocking noise comes from the rear of the car. I do not believe it's my shocks, as there is no noise when going over bumps, only accelerating and stopping. What may be the cause? Control arms maybe?

I get a rhythmic thumping sound from my right front wheel when braking. The sound gets slower as the car slows, and when very slow sounds more like a grind than a thump. I can feel the vibration through the brake pedal. I've had this problem before, and had my wheel bearings replaced -- fixed the problem, but after about a year the sound came back. Just had the car inspected and brakes are in good shape (at least those parts checked out by the state inspection). Could it just be that I need to get the wheel assembly tightened up? (It's a '99 Honda Civic with about 145K on it, if that matters)....

My 2005 F150 is making a thumping noise in the front end. It increases as speed increases and is more pronounced when turning wheel left and almost goes away when turning to the right. Sometimes at higher speeds I can feel it in the gas pedal. Seems to be coming more from the driver side but I could be wrong On that.

I own a Jeep Grand Cherokee 2006 V8 4.7 with 133,000 miles. This week I went to a Quick Service Oil Change , after receiving an oil change they informed me I needed a Differential Fluid Change , that I "should have " had one at my last visit and couldn't wait any longer. After receiving the two , I left and not even fifteen minutes later , I attempted to use my breaks approaching the end of the highway.
Instantly the car started making an extremely long banging / thumping sounds along with the a lot of shaking and the car proceed to dead right there. I got it towed home , the company is supposed to send some one to come do a once over. What it could be? As sad as it sounds, I have a feeling they will do a look over and claim they don't know what is wrong or that it isn't there fault in any way.

On our 2008 Prius, while the brake assist pump is running I get a steady thump-thump-thump-thump noise, as shown in the video below. If you put your foot on the brake the noise stops. The brakes operate fine and there are no warning lights on. What this might be? It's coming from the passenger side of the car, and oddly it's loudest under the car near the back seat. 86,000 miles on the car.

Hearing a sloshing scraping thumping sound coming from their 36 gallon tank under hard braking accelerating? It's loudest when the tank is between 200 and 150 miles to empty, I checked the spare tire and its tight, haven't had a chance to crawl under and look around yet though, I think something inside came loose. 2013 XLT.

I have recently bought a 04 f250 6.0, and it has the intake thumping noise that varies speed with idle... I was told it could be a broken rocker, a bent push rod, or a broken roller... I am not that much experienced with diesels. I've spoken to the dealership, and they don't wanna fix it, they said it wouldnt hurt it to drive it like that, but the noise bothers the hell out of me, and everyone notices it. so i wanna get it fixed. I am hoping its just a rocker. if it is just a rocker how deep am i in? truck has 240xxx miles on it, and runs perfect other than that noise.

I have a 2004 F150 4x4 5.4. Over the last few weeks I've noticed that when the truck has been parked for even a short time, when I start to move out I am getting a thumping noise from the rear, almost sounds and feels as though I am driving over small speed bumps, but once i get going it seems fine. Where to start?

Quick back story, bought the car a year ago, seller told me it was in an accident and the radiator was replaced. He let me know that the discharge AC hose was missing and that the other hose was disconnected. I also noticed that the low pressure cap is missing. I recently ordered and installed the discharge hose with the intention of filling the system later.
I have always noticed a noise/vibration coming from the passenger side when braking at low speeds. I havent noticed at higher speeds but maybe there is more road noise. The best I can describe the noise is that is sounds like a compressor running. I have a hunch it's the AC compressor and might be related to the regenerative braking, but I am no expert.

My Toyota Corolla (2004) sometimes (not always)has noise when braking, but I had the brake pads replaced and rotors resurfaced in December last year. What might be the problems?

2004 GC, 6 cyc, 2wd. Had TERRIBLE noise & vibration when braking but problem was intermittent, no codes generated. Everybody suspected ABS problem. New pads, new rotors, new ABS module no luck. Frequency increased but severity decreased. Technician finally experienced one occurrence, identified & replaced a weak steering stabilizer. Problem has surfaced again but not so severe and appears to be increasing in frequency.
My best description is when braking from 45-50 mph, Vibration & noise begins at about 35 mph, increasing in intensity until about 18-20 mph then stops. Seems to me that the transmission downshifts and the noise stops. AMCO suggested a cracked flywheel or loose bolts on the torch converter. Also the engine idles at 1100-1200 rpm on start-up then goes to 850 rpm - will not go lower. Does this sound like a transmission problem? The transmission was rebuilt/replaced at about 94,000 miles and the problem started at about 111,000 miles.

Bought my Prius (2005, with 160K miles) about a month ago and since I've had it I am hearing a metal on metal grinding noise when braking at low speed. How loud the sound is depends on how hard I am on pushing on the brakes. One of my co-workers has the same model and said that his does not make that sound. Not sure if its just because it has after-market brake pads or something? This noise only occurs when braking at low speeds (below 10 MPH) so I assume its an issue with the front brakes.
Is this something I need to get looked at by the dealership? I had a local mechanic that worked on my old Honda beater take a look and he said that the rotors and brake pads looked new and wasn't sure why they'd make noise.

I have an 06 Prius that I have had for about a year or more now. When I bought it, it needed a transaxle. I replaced that and have been driving it since. I have this problem that seems to be getting worse. When I push the brakes the car will make a popping noise, and it seems to be getting more frequent. I do not get any noticeable noises when turning or just driving normally.
The noise is quite noticeable, when I am in a parking lot and hit the brakes next to someone, people will give me the look like "what's wrong with your car". I am not positive where this noise is coming from, but my best guess is that it is coming from the right side. The popping seems like something is bound up and then releasing. I can also replicate the noise some times when I initially accelerate. My best guess is that it is being caused from the engine/trans weight shifting, but I am not sure a motor mount can make the popping noise I am getting.

So my dealer diagnosed my 2007 Prius with a transaxle issue, but what bothers me is that it doesn't make the sound all the time. When I brake lightly, there is no sound and when I brake heavily there isn't either. It is only when I do a medium brake above 7 mph of course and around 20's mph range. I am hoping for something besides the transaxle...maybe a wheel bearing...anything.

I may be worrying over nothing but lately when I brake or accelerate I hear a grinding noise on my radio. I listen to AM. With my other vehicle it usually meant there was a problem somewhere.

My car was making a weird grinding noise when braking above 7mph. I did the neutral brake thing and seems to go away sometimes. The dealership said it needed new rotors and brakes, so I went ahead and did that with them, then called me to let me know the sound did not go away. Now they are stating my grinding noise is coming from the "inverter generator" which is what they said was the transmission. I am just curious why this goes away sometimes and if it's related to my previous issues with the car.
