I have been having some major issues with my truck!
The whole truck is vibrating when on. When I accelerate I hear a loud noise like something is hitting a fan. I'm scared to even drive it. The rpm's have been jumping around.
What could be causing this? I already replaces Fuel filters.
So my 98 f150 xlt 4.6 is having a issue where the truck is jumping from 1500 rpm to about 2500 - 2600 rpm. You know sitting there trying to get up to speed. then all the sudden i look down and its at 1500 rpm. but still not really going anywhere. So i give it a little more throttle or gas and it jumps from 1500 to about 2500. Its been like this for a month but i thought it was crap fuel. What is the cause or maybe a solution?
View 4 RepliesWhen I accelerate i get a loud squeal until my truck changes a few gears. Its only when I accelerate and only if my trucks warm and has been running or a few minutes. Cold start it wont happen right away. What it is or could be. Changed my serpentine belt that didn't work...
View 7 RepliesI've got a loud, intermittent, swooshing, vibrating noise from the front left wheel area at highway speeds. I put a camera down there and saw that when there was noise, the front driveshaft and front left halfshaft were spinning. When they stopped spinning on their own, the noise stopped. Hubs are Warn Premium (gold) and unlocked. Unit bearing already replaced. What could it be?
View 10 Replies2001 F-150 4.2L automatic, 189k mikes. Gas pedal would do weird knocking/vibrating. It would do it at idle & under acceleration. Gas pedal would knock & sometimes slightly move or kick back at you. Felt like someone was lightly hitting it with a small hammer. Well there is not much to the gas pedal assembly; pedal, throttle cable & mounting bolts/plate. Looking under hood, a bracket from drivers side of motor was pushing back against firewall, which was pushing into gas pedal mounting bolts. I grabbed the bracket & it came off motor. Nothing else attached to bracket. Looks like it rusted off and was pinned between motor & firewall. Well, this fixed the gas pedal problems. But now i wonder what the bracket is & whats it suppose to hold??
View 3 RepliesThe speedometer on my car works intermittently. When I accelerate and release I hear a loud clicking noise and my speedometer and rpm stop working. It will jump from different speeds dropping to zero. Is my speedometer on its way out or could it be something else?
View 2 RepliesI have a 2003 Camry 2.4 LE with 120k miles on it. It's been very well taken care of. As of now, here is the maintenance that has been completed at my dealership. By the way, I don't trust dealerships, but I do have one nearby that is actually beyond outstanding (and I know a little about cars):
- Regular oil changes, and always with 5W-30
- Radiator flush and thermostat replacement
- Tranny flush
- New front brakes, rear brakes cleaned, and lines flushed.
- Oil pan gasket replaced
- Valve cover gasket replaced
- Spark plugs replaced (at around 105k)
So, with this information being provided, here is my current problem. Lately, as I accelerate between 1500-2500 rpms, the engine has a louder than usual (but not too loud) groaning noise. Basically, the engine just sounds a tad louder than normal along with groaning noise. The engine also feels as though it is running kind of "dry" (if that makes any sense).
Now, above 2500 rpms, it's just fine. It's amazing on the highway, but I feel as though it has slightly lost acceleration in the city. The only issue with the car is the infamous greyish/blue smoke at startup, but that rarely happens and when it does, its a small amount of smoke, and it has never affected it's performance or gas mileage. Another thing is that I had to have that dreaded oil splash guard removed, because apparently the timing chain punctured it and it was about to fall off.
This problem has been recent within the last month. Just before this, the car has been on a roundtrip to Tucson from Tulsa, and Amarillo twice, complete with 32+mpg on the highway! So, what's wrong? Serptentine belt? PCV valve? Cam or something underneath the valve cover?
I recently noticed my brand new truck with 5k miles has been making a humming /vibrating noise when shifting and when RpMs are above 2k. What this could be? It's a 2014 F150 stx 3.7 ....
View 4 RepliesI have a 97 f150 4.6, when I'm towing a load and trying to accelerate a little harder either to just gain speed or climb an incline I get this terrible crackling noise from my engine as if I was low on coolant or low on oil. But all my fluids are good. It even does it when I'm climbing an incline not loaded. What this could be?
View 2 RepliesStarted the car the other day and a loud whining noise followed by the car "jumping" when I stepped on the gas. It would go/stop for a second, then shut down. Mechanic who is not a Prius expert said it was the tranny. He could put in a used one (77k miles). Car has 250k miles on it. Is it worth it? Or should I just part it out. I'm worried about things like the battery going next.
View 8 RepliesI've had this truck almost 2 yrs now. It is not a 4 x 4. The trouble I am having is on the driver side. What happened first was while I was driving it i heard a loud squealing noise then a loud pop. After that the truck seemed fine I checked under it and everything looked ok. After that I drove it to a couple stores did fine but i heard the loud pop again. Once I left the store I was driving on the highway and it jerked to the left and i heard a grinding/rattling noise. I put my flashers on slowed down and every once in a while it would still pull to the right but the grinding noise remained constant. I parked it waited for a tow and i turned the truck around and drove it up the ramp there was another pop sound but I didn't hear the grinding. It seems to happen on and off. And it doesn't matter if I am turning or going straight.
View 2 RepliesFirst off I have a 1997 F-150 4.6 with 205,000 miles on it.. stock engine and tranny. It's been a great truck and never given me any major problems. But recently something under the hood (wish i could be more specific) makes a really loud HUMMING noise (almost sound like a trumpet). For example- say im driving on the highway and i let off the gas, this humming noise will appear and it is very loud, but right when i give the engine some gas the humming goes away.
Or also when I am driving through town, when i come to a stop light, let off the gas to apply the breaks, this humming noise will come about. what i have to do is stick the truck in neutral and give it a big rev (which i do like hearing my exhaust so it isn't always annoying) and then it stops. note though, it doesnt happen every single time i let off the gas, however it is pretty frequent.
do yall think this is in the air intake system? thatd be my only guess because when i rev the engine it quits, but one thing is it sounds like it comes more from the passenger side of the truck, and it seems to occur more often when the temperature outside is cold. im completely stumped by this one, ive never heard anything like it.
I have a problem with my reverse in a 5 speed 105 hp Tdi. It jumps out of place when i try to move the car, makes a loud grinding noise and pops back in, I'm guessing the selectors are worn or maybe the teeth are too. My question is, how hard is it to replace the selectors (if it is the selectors that are worn of course), what is the cost of getting it done in the shop and most important does this sign mean I will have the same problems with the rest of the gear in nearby future?
View 2 Replies2001 F150, about 3 weeks ago I drove through standing water that was probably about 2 feet deep, as soon as I did that the truck started jumping real bad and almost died. I drove it around for a little while and it started to run better. After that it started to feel like it was misfiring badly. Between 40 -50 mph on the highway just giving it gas a little the jumping was pretty bad.
I decided to change out the plugs, thought maybe water got onto them and this was causing the issue, this was my first time changing the plugs in the truck and it was not nearly as bad as it could have been! I was able to do all of the plugs except number 7. The fuel injection line is right on top of that plug and I did not want to remove it!
After changing the 7 plugs the truck is running better now, I have not yet felt the jumping that was happening, my problem is that on the 4 plugs on the passenger side all 4 looked to be covered in oil. My question is does this mean my head gasket is blown and how long do I have before I am going to have to put alot of money into this truck to fix this issue?
I was pulling out of my driveway (it's quite steep) in 4x4, turned onto the road and heard a clunk.
I then took it out of 4x4 and continued on. I noticed it was vibrating more than usual. I turned out of a friends driveway (not in 4x4) after that and thought I heard another clunk. The vibrations seemed to get a lot worse after that.
While driving 50MPH one day the car suddenly started making a very noisy, loud sound and would not accelerate when the gas pedal was depressed. I put the car in neutral and pulled off the road. The engine is running great but the gears are now all screwwy. R = neutral, and all other positions "N D 3 2 1" go forward. I put the car into one of the forward gears and it moves, but only about 20 feet before it ceases to move without a LOT of gas, then it is only 1-2 MPH.
View 2 RepliesI have a 2005 hyundai accent, 62000 miles. When I accelerate there is a vibrating/rattling noise that sounds like it's in the back left side. It only happens sometimes. It happens when i accelerate slowly or up a hill, and if i press on the gas it stops. I thought it was the muffler, but I got the car inspected in May and it was fine. It's been doing it since before then. My dad said it might be a loose heat shield vibrating. It seems to be getting more frequent with humid weather. Should I be worried?

Some weeks ago a noise started that sounded like fan blades striking against heavy plastic fan guard. At first I thought it was coming from the transmission/Transfer case area but after a few weeks of listening to I now believe it's coming from behind the dash area, however, I can't find any reason for it be from there.
The noise usually starts around 45 MPH
I checked the heater fan and it appears to be Okay. I don't know of any other fans in that area.
When I drive my car past about 3000 rpms then let them fall i hear an odd sort of vibrating noise coming from the turbo between where ever I rev it up to and about 2600 rpms. Is this normal? Its fairly quiet and can only be heard without the radio on and if your listening for it. This worries me because I've only had this k03 for about 5000 miles .Some background info I am chipped with uni at 20psi, full 3" turbo back and an 007 dv.
View 3 RepliesMy 99 F150 4x4, 5.4 triton all of a sudden got very loud and has a loss of power. To me, it sounds like a cylinder is straight open to the atmosphere. I at first thought a spark plug blew out or an injector somehow came dislodged but I checked and everything seems ok. It's coming from the passenger side somewhere but is so loud under the hood I can't tell exactly where.
I took the valve cover off to see if a valve is stuck open or something, but I don't really know what I'm looking at as far as internal engine goes. I turned the crank by hand with a ratchet and the valves seem to follow the cams, but I've never inspected valves before so don't really know what to look for. What could be causing this loss of power and incredibly loud noise?
t's a '00 extended cab swb 4.6L with 4r70w trans. I have a Hotchkis TVS 2/4 kit on it. It's been lowered 3 years now and I've never had any real issue. But I started noticing a small vibration through the floor so I took my driveshaft out to be balanced and new U joints installed. Ever since then I've had an audible "hum" from the rear whenever I go over 75mph. It only does this under load (hill, etc) and I don't hear anything until then. The driveline shop told me it was my pinion angle and I've tried shims with only slight improvement. I'll replace the driveshaft after I do a motor and trans swap down the line, but it's out of the budget for now.
