Ford - Ranger :: 1998 - Metallic Drivetrain Noise Only Upon Acceleration
Aug 13, 2012
The vehicle in question is a 1998 Ford Ranger XLT with the 3.0L 6cyl engine and an automatic transmission.I've done quite a number of repairs already and am now trying to isolate what might be causing this particular noise.
The noise itself sounds a little bit like a rotational metal on metal sound with a dash of two washers being vibrated together. It takes no effort at all to reproduce; put the car into drive and step on the gas. The truck will happily move forward, making that drivetrain sound.
Here's the thing..
1) If you're in park and step on the gas, there's no sound.
2) If you're in neutral and step on the gas, there's no sound.
3) If you let off the gas and coast, the sound goes away immediately. Step on the gas again, and it comes right back.
To me, this seems to indicate a motor and transmission mount problem. If the engine is idling, then it isn't spinning the drive axle or rear diff.Upon acceleration, the driveline might be torquing strangely and this in turn would cause the differential yoke to spin at an odd angle causing the noise. It'd also explain why all the noise ceases when I let up on the gas; there's no more load on the drivetrain.
I don't believe it's the axle or pinion or even wheel bearings, since the car is -quite- quiet once you let up on the gas pedal...

When stopped and accelerating normally I hear an audible clunk, but feel nothing. If I gently accelerate from stop it does not occur. 1998 ford ranger 4x4 ....

I have a 1998 Ford Ranger. My problem is jerky application of acceleration. I note slack in the cable connecting the pedal to the engine throttle. Is there any way to adjust this cable length to remove the slack.

I've been hearing this rattling, sometimes kind of a metallic ping, from the rear the last week. I thought it was probably the universal joints, didn't do it often, only under load between 1500-1900RPM roughly in second, third and fourth. I planned on working on it this weekend.
Today it started really making noise, sounds like valves rattling as though the timing was too high but it was coming from the rear end. It was making it all the way through the gears into fifth, even when cruising. Once it cooled down a bit it nearly went away.
I'm going to get started on it as soon as I can, but I can't get it in the shop to pull the differential cover and take a look right now. Dad's shop is full of crap, I live on top of a hill, not many safe places to get one up in the air properly. What is causing that sound?

While driving through a tunnel today I noticed a metallic rattling noise upon acceleration. It goes away immediately when I let me foot off the gas and when I park the car and rev the engine the sound does not occur.
A few days ago, I had to rapidly accelerate and it felt as though I lost power for a split second. I am not sure if these are related, but I am hoping its not some sort of transmission issue (unless that is covered under the hybrid warranty. What was the diagnosis?

I recently put an accidental extra 4 quarts, and I know hear a low thump ie like a piston but the engine runs fine and there is no power loss, just a simple draining off the pain I hope. The engine runs fine just notice this small metallic rhythmic thump on acceleration, and deceleration.

My 2012 F250 has begun making a noise. The noise is coming from somewhere in the linkage (drivetrain). It sounds like new knobby tires on a paved road but not constant more like (rrrr-rrrr-rrrr). The frequency of the noise increases the faster the vehicle moves. It does not make the sound while revving the engine in park and the noise does not change between dirt road of paved road, so I'm pretty sure it's not the tires or the engine. Could it be something like the tachometer needing lubricant??? Its kind of loud.

My '04 Explorer started making a noise like slamming in and out of gear. Felt and sounded like the transfer case was slipping or jumping teeth. Turning slow in gravel the left rear would drag like a spider gear problem.
It has the Auto 4x4 system, Auto-4H-4L. I pulled transfer case out and apart. No signs of teeth missing, slipping, nothing. Chain looks good, bearings good. Clutch pack good. No sign of any metal shavings in the case.
Pulled rear differential, one bad spider gear for the left axle is all I found. Not enough for the very hard slamming it was doing. U joints & axles good also.

I've been having this problem for about 2 weeks now, and I am trying to figure it out. I know the video is only 5 seconds but at least you can hear the sound, it only happens in first gear, on take off, about 2-5 seconds after the take off, and the sound is coming from the rear axle area. I cant figure out if its diff or brake related.

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.

1998 ranger 5spd... I have 117k miles on this little ranger and I recently took it on a little trip and since that trip it has a ticking noise under the hood as if the lifters were sticking. I believe it has hydrolic lifters in it. I put some sea foam in it 200 miles ago and changed the oil about 50 miles ago. I used Valvoline full synthetic and it seems like it has lessened the tick and it drives a lot smoother, in my opinion. Is there any thing else I can do to relieve that ticking? It is more noticeable when the engine first starts and is louder if i push down harder on the gas. It is not preset if i do not put that much pressure on the gas.

I have a 1998 ranger 2.5L engine. I took it to a Ford garage and they told me I have a rod knock..........I took it also to a good mechanic and he said the sound is coming from the lifters.
There is 172000 miles on motor and the noise started at 131000, and is getting worse. Should I drive it till it blows, or is there a way to tell what the problem is?

My Ranger has 296,000 miles on it. Most everything has been replaced except the u-joints. It's a 2wd 2.5L with an automatic. The motor was replaced at 228,000 with a used motor with 52,000 miles. The transmission has about 60,000 miles on it. All the bearings in the rear end were replaced about 20,000 miles ago. It has the most annoying whistling noise coming from the rear only sometimes. I don't know if it's the brakes being misadjusted or a bearing with a burr in it. It happens at random times but it's such a high pitched whistling you know everyone on the road can hear it too. There is also a driveline vibration, very minor though when over 60. However, I've had the drums checked and even had the wheels balanced many times. My friend said the ujoint grease could be dried up, but the whistling noise only happens at random, the virbation is anytime you're at highway speeds. It's not a violent vibration just enough to tell that it's not a brand new truck anymore. What it could be?

I have a 04 F350 srw , 6.8 . Recently developed loud whine from the rear . I had the differential (10.5 sterling ) completely rebuilt . It quieted way down . But I still had a couple of high pitched whines . Took it back and had the rebuilder ride with me . At first he couldn't hear it ( it can be faint but gets louder under a load , I pull a 40' trailer and didn't have it with me), when he finally started hearing it he said it might be a planetary making a little noise, just watch it . So I made a short run (450miles RT) . Same noises but I noticed that sometimes when I stopped and got fuel , it would quiet down for 50 or so miles . I got to thinking maybe it could be a rear wheel bearing going bad and the sound transferring through the axle to the drive line . It only did it accelerating ( before and after rebuild ) and got louder going up a hill .
Today I drove it in to town and parked it ( still the same ) and a couple of hours later after a cold front came through ( maybe 10 Deg. temp change) I got in and the noise was about 90% gone , but at 45 to 60 mph. it vibrates . Let off the gas , vibrates ,, Put it in neutral- vibrates, revved the engine in neutral - vibrates and no change from rpm diff. . As long as its rolling between 45-60 , it vibrates . Hit the brakes- vibrates.. I have had 3 mechanics check it out ( 2 good ones and one that the other 2 take what they cant figure out ). Left them all scratching their heads. Checked the driveline and I changed one U joint (prior to the short run ). All seems tight .

Drivetrain noise I cannot diagnose. I have a 2002 F350 diesel and have noticed over the past couple thousand miles a noise from the drivetrain that is hardtop identify. It is not brake related ( new and unaffected by brake application) and not rpm related. Most noticeable at around 50mph. Not tires and they are new and noise persists.
Front end has been apart for new hubs, brakes, rotors, wheel bearings. Noise continues. It has an oscillating quality and is somewhat like a lower pitch whine which gets more prominent as speed increases. Wondering about bearings associated with drive shafts? Are there some things I can check underneath to diagnose the issue?

Over the past couple of weeks my truck has developed a pretty consistent metallic buzz on light/moderate acceleration. At first I thought it was a heat shield rattling, but I've been under it a dozen times and can't find anything loose to make the metallic buzz that I'm hearing... I can pound on several places in the exhaust system with my palm and it seems solid/connected everywhere. V10 truck??

I'm back with another question! My 2006 Prius now has 60,XXX miles and the other day while driving with the windows down, I was climbing a hill to my house and when the engine is at a certain RPM, there is a metallic sound that comes from under the car, but more in the front. You can't even hear it when the windows are up barley, but more when they are down, you can hear it, especially when you're beside a wall or guard rail and the sound can reverberate back.

I have been having a grinding/metallic sound when going up hills in 4th/5th gear. It sounds like if you threw metal into moving parts. I believe it's coming from my engine or transmission. When i was at the dealer last month for a campaign and ecm upgrade i mentioned this problem and they replaced the vcm motor assy, however the problem still exists. What could be causing this problem?

2007 3.6 Wagon Sport. My wife has the 18" Samarklan wheels and automatic transmission. We have complained to the dealer since the beginning with only the "you need new tires" response. Well we got new tires last year and the noise was the same. I've had 18" on my old '00 S4 and current '00 A8 with nothing near this amount of noise.
The sound is most like a groan and doesn't seem to be coming from the engine. It's seem most noticeable at lower speeds coming/coasting to a stop, but does not seem to vary with or without braking. It doesn't seem to vary based on turning either.
I don't ride in her car much, but am always shocked how loud it is when I do, as it's so dramatically louder. Also the HVAC 'percolates' constantly which is generally only noticeable at idle. This is a small, secondary concern. I everyone's Passat really this loud?

I'm having a problem with my Prius. It pings under acceleration and it sounds like something metallic is rattling. It only happens when I use 87 and 89 oct. I use 91 premium to reduce the ping however, gas prices are rising and I want to go back to 87. There are no warning lights or anything and the ping has been happening for quite some time now.

I've been having a this rattling sound metallic type of rattle when I'm under load, meaning acceleration, on flat or hill side roads, then the sound goes, someone told me it can be the center shaft bearing..
