Ford - Explorer :: 2000 - Consistent Knocking Noise Increases As Engine Speed Increase
Jul 27, 2015
I'm looking at a dirt cheap Explorer 4.0, has been sitting for 2 years. Runs nice, with a double "knock" noise but quieter than a rod knock. Idles smooth at 600 rpm, "knock" is consistent, but increases as engine increases speed. Has 2 year old oil, and 2 year old gas. Would a tune up support it, and revitalize it, or is the engine almost dead. Still drives, didn't push it to hard. Interior is 9/10, exterior is 10/10. I have him down to 600. 4x4 works, and feels good.

I have a 2007 Ford Fusion SE 2.3L 4 cylinder. It has approximately 94,000 miles on it. I purchased new Sumitomo tires with a 100,000 mile warranty in February of this year. They were balanced and aligned at the time of install. So far they have been very smooth and quiet with great grip. About 2 months ago I started hearing a noise that sounds like uneven tire wear, a sort of rhythmic rubbing or wobble sound that increases in frequency as the speed increases. It is most noticeable at speeds between 30 and 50mph. I rotate the tires every other other change (at least twice a year) and had the alignment done again in late October. I am hoping that there is nothing wrong with my virtually brand new tires. Is there anything else it could likely be?

My 2000 B5 1.8t began getting the Low Oil Pressure warning light over the winter, and has gotten progressively worse. I added a mechanical oil pressure gauge and I'm seeing about 20 psi on a cold engine at idle. If I rev to ~2500 the pressure DROPS to between 5 and 10 (and triggers the STOP! light).
I tried a bottle of autoRX, but probably too late- I could only run about 200 miles before the STOP! light wouldn't allow me to get out of the driveway.
What might cause the pressure to DROP as engine speed increases? a Clogged screen or worn pump possibly? It would be nice if it was something I could correct without pulling the engine (but I'm not expecting that).

96 Ford Explorer, 78,000 miles After about an hour on the highway (60 mph), the vehicle slows and cannot increase in speed. It does this until it slows to less that 20 mph. Pushing on the accelerator increases the rpm, but does not result in an increase in speed. It only does this after an hour or more on the highway (city driving does not cause the problem). No one can diagnose the problem; already took the vehicle to the dealership and a transmission specialist (both said nothing was wrong). Hoping very much to keep this vehicle.

I dropped my car(2003 explorer XLS) for a brake pad work at an auto shop. but when I went to pick it up, the engine made big knocking noise when starting. the mechanic told me seems the engine having problem. he was shock too because he admitted the car was fine when I dropped it.
He didn't do anything except the brake work and top of some oil(I told him to check the coolant and oil level). I towed it to dealer and was told the engine is bad, I need a new engine. he didn't give exact diagnosis, said that will cost more than $900. he also said the mechanic seems didn't do anything wrong.
The car doesn't show any other symptom except the noise, what might be the problem? I want to try whatever I can before rebuild the engine.

2000 Crown Victoria, 207K miles, 111K on current engine
My car has been an absolute champ since I took ownership of her at 133K miles, and to this day runs trouble-free. However, it's just started making a noise that's got my scratching my head. I can only describe it as a "puff" sound. It's consistent with engine speed (higher RPM = faster puffs), and seems to get louder the more open the throttle is. If you let off the gas and coast, the noise goes away.
What's kinda confusing me is that the noise does not occur at all while the car is not in gear. If you park and rev the engine, the noise doesn't happen at all. All fluid levels and conditions are good, and there's been no loss of power or other issues from the engine or transmission.
My only guess is perhaps I have a teeny-tiny pinhole leak in my exhaust somewhere. The sound seems to be coming from somewhere very close to the engine, but since it doesn't happen when parked I can't pop the hood and look around for where exactly the sound might be coming from.

I have a 2000 Neon with about 170K miles on it. with in the last 2 weeks it has been having a problem with acceleration. When i start to drive the RPMs will get up to 4 before it will start to move. Also when i am drive and need to pick up speed the RPMs will also go up to about 4 before it starts to pick up speed, but will drop back down when the speed goes up. I have found a little oil in the spark plug tubes and will be changing the seals out, and I have cleaned to MAP sensor as will. What is going on with my acceleration.

2015 F-250 Super Duty, 6.2 L Gas with 6r140 Transmission. I have 13 K miles on my truck. While pulling my travel trailer up a hill the transmission kicks down thru the gears, which is fine, but as I crest the hill and in 2nd gear, the engine begins to rev up and the speed increases, the transmission will not automatically go into3rd gear. I have tried to let up on the gas pedal, but it remains stuck in 2nd gear. I have to shift to "Manual" and then put it in 3rd gear. Then it shifts up as it should. I have tried with the transmission in "TOW' and not in "TOW". I have even tried it in "Cruise Control".

Thats the sound coming from I think the front left area and the rate is proportional to speed. It only occurs at slow speed from about 5 to 15 mph and it seems to only occur for about 30% of each rotation. I plan to jack it up and check tire wobble or if the sound occurs during free spin. Any other things to check?

Over the past 2 weeks, started having a whining noise from front end. It seems to be coming from the front passenger side. The noise starts at around 30 mph and increases with speed. Very noticeable at highway speed. Sounded a bit like tire noise. I did rotate the tires, front to back, but noise persists from the front.

I recently had my 2002 1.8T in for clutch replacement at the dealer and they came back and said the crankshaft was bad ( the car was occasionally making noise when pushing the clutch in, they thought it was a throwout bearing) I took the car back to bring it back to an indie, and it is loud at idle and while accelerating (sounds like a chattering noise that gets faster as speed increases) It's now sitting in the parking lot. My question is, am I going to have to put in a whole new engine to fix this problem? can just a crankshaft be replaced?

I recently purchased new tires and rims for my Mazda 626 thinking it would get rid ot the loud tire noise (2 rims were bent). However, the noise still exists. I cannot seem top pin point the source of the noise but, it increases with speed.

Starting at about 30mph there's a humming noise that gets louder as speed increases. It doesn't seem to change if I am steering right or left and i have no steering wheel shake or any sort of noticeable bumping at 60mph. Could this just be my tires making noise, they are quite worn by now.

2003 Subaru Forester with 130,000 miles. We put new tires on two months ago and when I started hearing the wah, wah, wah noise coming from the back of the car (rhythmic - increases with speed of car) I assumed on of the new tires was bad. It isn't. Also pulled the brake drums and cleaned everything there up.... What this might be?

Recently I have been hearing a humming noise that increases with speed. I don't get it when the car stops. I think it's coming from the rear but only when the car is moving and steadily increases in volume as speed increases and comes down as speed comes down. It's not coming from engine or transmission but coming from the rear wheels. Could it be a bearing? or both bearings? Is hard to make out if it's left or right of the windows when the windows are closed. Car drives great and has mileage in the 80's

When turning in both directions, front end makes a CHEEP-CHEEP-CHEEP-CHEEP-CHEEP sound. Frequency increases when speed increases.Brakes are NOT engaged when this happens. Goes away when coming out of turn.
I am sure the problems could be multiple, but what is your first thought? Not that it matters, but its a 2002 Chevy Trailblazer.

However it was road tested without the trailer.

I have the Golf 2.5 just under 5K miles with the 15" steel wheels and just recently I've noticed a clicking noise on both the drive and passenger sides. The frequency of the noise increases as I increase speed so I assume it is a tire/wheel issue. Sounds like its coming from the back but hard to tell.

I have a 2000 Ford Focus automatic dohc 157K. About two years ago, it started making a noise that has gotten progressively worse. It is very hard to describe. It sounds like an intermittent flopping noise that you would expect from a bad tire. What makes is strange, is that the sound is not consistent with the rotation of the wheels. It does however increase and decrease with speed, but again it's inconsistent with the wheel rotation. It does not roar, or whine like a bearing, and there is not popping noise you usually get with a bad CV joint.
It seems to subside when I turn to the right and become a little more pronounced when I turn to the left. I have new tires, a new axle and wheel bearing on the right (passenger) side of the car. The repair shop checked all of the bushings and bearings, and cannot hear the noise when it is on a lift. I also just changed the sway bar links and all the engine mounts. You can feel the floorboard bumping along with the sound, but it does not telegraph through the steering wheel. There is no shimmy or vibration.

Recently had my 105K maintenance done which was water pump and timing belt plus whatever other misc belts go with that. Had it done at an indepentdent shop. Since the job was done we have noticed a high pitched whine that increases in pitch with RPM or speed that we drive (literally sounds like a jet engine whine). I took it back to the independent shop and he suggested it was our transmission. I have noticed no difficulty when changing gears nor any engine warning lights. I contacted Honda and our vehicle was part of a transmission recall in 05 that was done already. Other sources have suggested that the whine could be the belt being too tight or the water pump. Shop supposedly used all honda parts. Should I take it back to him again and suggest that the belt is too tight? Take it to the dealer and see what they think?

My LS 460 has a pulsing wheel/front end noise that seems to increase as the speed increases from 5 mph to about 30mph and then fades out. I brought it in for service and they test drove it twice with 1 and then 2 service techs. They could hear the noise and said to me that they think it is cupping on the tires. The tires are in great condition inside to outside.Tires have only 14000 K. I switched the back to the front. The same dut-dut-dut-dut sound increases as the speed increases to about 30mph.
I believe that the noise is something more serious. I noticed that when the suspension compresses over a high point in the road at say 20mph the sound will stop during the time the car is comming of the high point in the road. Could this be a bearing/suspention- or something with the breaking motor because I also have been using the break hold feature for several months and not sure if that could cause harm. Also I do hear more grind or grumbling when turning the wheel to the left at low speed then when turning to the right.
