At the above speeds my truck has a rattle/ticking. I think its the cats but I'm not sure. I checked all the obvious like the heat shields and stuff. The truck has 118000 miles on it and has been in So. Cal. its whole life.
View 6 RepliesI have a 2001 Ford F150 4.6 liter V8 Super Crew. I use Castrol full synthetic oil and Fram filters...changing oil about every 10,000-12,000 miles and change filter at half way point.
Here is my issue: I noticed a slight rattle on passenger side of engine a few weeks ago but engine ran well & I wasn't sure if it may be a pulley from AC compressor or something else. It wasn't bad at all...more like a ticking sound.
Yesterday I drove to work with no problem and when I got ready to leave 9 hrs later, I noticed rattling was getting worse. I ran about 2 or 3 miles down the road and my oil pressure flatlined and light came on. This is the 1st time it has ever happened. By this time the rattling sounded bad, almost like it broke something on both sides of engine around valve cover area.
I pulled over immediately and had truck towed to shop down the road from my house, When my mechanic started it up this morning it had oil pressure and rattling was not near as bad. I put a new oil filter on it & topped off oil. He could not get to it today so I drove it home today for the weekend and by the time I got home (3 miles) it did same thing...flatline, oil pressure light on and rattling with no power (very sluggish).
I did notice the oil pressure light came off & on and gauge went up and down a couple of times before I shut it down. What the problem is? Oil pump maybe? I just didn't think oil pumps usually fail.
My brother's truck is a 2001 reg cab manual 4x4 with 4.6 and auto tans. Truck has roughly 130 i believe on it, this mornig he had blower on high in defrost position about three miles from leaving his apartment he said he heard a POP and the blower quit. No burnt smells or anything he said. SO Im gonna check the fuse first after that what should i do? Is there a relay for the blower? And do the new trucks have a resister for the blower speeds? If so how do i check these parts?

View 14 RepliesI engage my 4wd all the time to keep it working and lubed up. tonight i turned it on and it was making a light clicking noise like a card in the spokes of a bike (not loud) and there was no vibrations or nothing that really sounded bad..what could be making this noise, what should I look for...
View 5 RepliesI have a 2001 ford truck and it makes a growling sound when i am turning right but is not when going straight ahead wondering what part in the rear end could be making this sound.
View 2 RepliesI'm wondering what is going on with my 2001 F-150's 5.4L Triton engine. Recently it's been making this noise that I can best describe as a "rattle" from the passenger side of the engine. It's not a constant rattle, it comes and goes every few seconds.
It sounds like it's either from the valve cover or timing cover, so I was thinking maybe it's the feared Cam Phaser failure, however the noise doesn't seem to match what I've heard from other videos of confirmed Cam Phaser failures.
I've attached a link to a video of the noise that I made. It also has a lifter tap from the opposite side of the engine that may be noticeable in the video. It has been present since I bought the truck two years ago, it hasn't gotten any worse and it isn't what I'm concerned about.

I just installed a cold air intake on my 01 f150 with a 5.4 and as soon as i started it after the install there is a loud humming coming from the intake but with some throttle it goes away. ive looked around on some of the other threads that suggest the iac valve usually causes this humming noise but why would it go bad with the install?? also i broke iac breather trying to remove it from the old hose to install with the new hose so i just connected the new hose directly to the inlet behind the intake until i can get another one to replace it. could this be causing the humming as well??
View 14 RepliesI have a 2001 F150 4x4 4.6L Auto trans. 96,000 miles... I purchased it in Jan with 93,000. About a month ago it started making and occasional knocking noise coming from the engine, this noise was heard at idle in park and in drive. when I revved the motor it would go away but as the idle settle back down you could hear it again. the noise would go away as I was driving and come back with no rhyme or reason, I put a stethoscope on the engine and it seemed loudest under the oil pan. The oil gauge is up between 5/8 to 3/4. Fast forward to now, When I start it I hear a scraping almost grinding noise that resonated thru the cab it has the same intermittent characteristics. I think I am going to remove the serp belt, remove the trans inspection cover next and see what happens. Oh I did put a scan too on it, no codes but did notice 1 long term 02 sensor trim was staying around -.618 if I remember.
View 11 RepliesI have a 2001 supercab 4x4 with a 4.6 in it, it has 186k on it and the only issues I've had was a misfire not to long ago. I replaced the plugs and coil packs and fixed that issue. 2 days ago she ran fine with no issues and this morning I went out to go to the store and she wouldn't start. All the dash lights come on and all of that normal stuff when you turn the key. When I turn the key I hear what sounds kind of like a clunking noise towards the bottom of the windshield and the middle of the dash. The starter does not engage, no nothing, really confused here. I thought maybe the battery was bad so I put my jumper on it and tried but again nothing happened.
View 14 RepliesI just came back from a long trip and during the 400 miles drive I started to hear noise coming from my differential - kind of like a constant high gear loud noise. I will hear this noise when I start to accelerate and it will only gets louder and louder as I go faster and faster. I had a pinion seal leaked fixed last week and I checked the fluid and it is full.
View 9 Replies2001 F150 SCAB with 74,000 miles. There seems to be a whistling noise coming from the front axle. It is definately a rolling noise. I can shift into neutral and put it in 4H and still have the noise. Brakes are good, tires are fair... I just rotated my tires (criss-crossed front to back) also sprayed all of my boots with silicone spray. Still has a whistling metal to metal bearing sound. When I have the front jacked up and spin the wheels, there seems to be a decent drag turning by hand. I don't remember having much of a drag before.
View 6 RepliesMy air conditioning compressor is rattling and grinding. I am trying to determine if I need a whole new unit or just a clutch assy. I can say this, when running it's rattling, but when the clutch engages, it clears up.
Would I be right in assessing it's the clutch? 1998 250 5.4 .....
2001 f150 extended cab flareside 4x4 4.6L v8, M5od manual, 196,539 miles this morning. the clutch slave is going out so I have some grinding and extra noise but recently the motor began to run like crap. I took it and coded it. "p0403, cylinder 4 misfire" is what it read on the obd scanner screen... I had a similar issue with the COPs not working and actually allowing water into the spark plug cylinder. I replaced them all at 100,000 miles or so with new motorcraft plugs at that time.
Fixed the problem and nothing since that time. Not sure why I did them all but I did. i was dumber 96000 miles ago. I also took down the intake and cleaned all the ports and crap out of it also. Yesterday took out #4 (on passenger firewall) and it looks fine. No evidence of leak, spark plug a light tan, firing well without problems, and even gaped properly still. My question is first I understood the p0403 to be EGR related, not cylinder #4 misfiring...seems odd.
2nd: I'd like to avoid just throwing parts at this problem. The EGR is simple enough to replace and if that's what is needed so be it. I'd rather do it right the first time. I've checked all of the vacuum lines, fittings, attachments. No leaks detected with smoke/brake fluid tests either. Good suction at the PCV, all good.
2001 f150 xl with 151800 miles 5.4l had it for a few years now I get a humming type groaning coming from up front. only when in 4x4 and only at lets say 25 mph to 45 mph .seems to be worse when slowing down especially the slower you get then around 20 or 25 its gone. it is still quite noticeable on acceleration and after 45 its gone. Truck has always been a little noise while in 4x4 weather it was an issue that had already started or if that's how it is. This is my first 4x4 truck.

Still have scrubbing noise when breaking hard. I do not hear any noise when driving regular or when normal breaking. Differential fluid was a tad low. Applied fluid. Still have scrubbing noise. No leaks at hub seal or pinion. Bearings ? Maybe?
View 5 Replies1997 F150... Truck has slowly started getting worse and worse performance. About 3 weeks ago the truck started rattling from the exhaust, Towing my trailer the other day, the truck had NO power, I thought it was the plugs, so I replaced them.
Now the rattle is worse (no lose heat shields). I am blowing the little tubes off the drivers side exhaust manifold, the ones that go to the DPFE sensor.
Did I mention, that the truck has no power, sluggish, now I am dumping hot exhaust fumes into the engine compartment. Still got the rattle underneath.
I think the cat is plugged up on the drivers side. (which probably explains all my symptoms)
Any other reason for the rattle literally coming from the drivers side cat and the little tubes being blown off?
I bought a 2002 f150 4x4 with a 4.6l. It has 250k miles on it. a couple days ago. It had no problems at all during the test drive or for the 150 miles home. Yesterday after it warmed up, the oil pressure dropped to 0 while at a red light and had a rattling noise. Not a knock but more of a rattle. I can't isolate where the rattle is coming from. Oil pressure comes back with just the slightest of increase Of RPM and seems To have plenty of power while driving. I had read to check the pressure manually but with the noise I sense there truly is a problem. the oil appears clear and is full. What I should be checking on this.
View 1 RepliesI am having trouble with my 2001 F-150. Starting yesterday it would not start. At 1st i thought it wa the battery, so i took it off, charged it, put it back in the truck and still no start. There is a clicking noise coming from a relay in the cabin fuse box, disconnected the battery, removed relay to inspect and everything looks good. After plugging it back in, and connecting the battery, the truck still wont start and there is a clicking sound coming from the dash near the radio. Rhis is my work vehicle!!!
