Ford Super Duty (1999-2016) :: 2008 F350 - Strange Noise At Higher RPM
Dec 3, 2013
I recently switched back over to the 5.4 from a diesel. It's a 08 F350. I have about 38,000 on it now. I have no complaints so far, a little less power than the diesel, but I don't tow much anyways. The only thing I can't figure out is a strange noise at around 2500-3000 rpms shortly before a shift sometimes. The best way I can think to describe it is that it sounds like a turbo fart in a diesel. Almost like someone is putting their finger over an air hose on and off a couple times. It doesn't do it all the time, and doesn't shake the truck, or effect the shift at all from what I can tell.
I've put it through a lot of different shifts just to see if it might be transmission related. It downshifts and upshifts perfectly without any noise or slipping, and the fluid looks just as clean as brand new. No smell or anything either. It doesn't feel like torque converter shudder to me either as i can't actually feel anything in the truck, just the small noise. To me it almost sounds like it's coming from under the hood. I'm not overly worried about it right now, because it isn't effecting the way the truck drives or shifts at all, I'm just curious what it could be.

In forward drive or reverse, I hear a rotational noise that almost sounds like the bed creaking when you're getting it on. As I go faster the noise goes faster until drowned out by road and engine noise. The noise is unaffected by applying the brakes. I jacked the truck up and spun tires as fast as I could by hand and got no noise but when I lowered it back to ground and had the truck roll the noise was back. Noise is not affected by turning wheel.

Every time I apply brakes I hear a weird humming noise, as well as no stopping power. Checked fluids and pads and everything is where it should be. I heard abs can cause this but not sure on that. I know my master cylinder has a very small leak but it hasn't lost any fluids of that sort. I'm lost. I don't know where else to look.

'08 F350 6.4l 4wd, I had the truck come in with a exploded transfer case. (See pics). Ive read all about this happening to many others. The truck still drove, hubs not locked, plenty of fluid in the TC, pretty sure it was the double Cardan that did it. Anyways I replaced thwith TC, replaced the front driveshaft, filled the TC with recommended fluid. Test drove and drives great, shifts fine. Only until I turned left.
At slow speeds turning hard or 15-20 taking a turn, it sounds like a ratchet clicking from somewhere on the left side, right around the drivers door, from what I can hear from the cab. Does it in 2wd, 4wd hi/low, hubs locked or not. I changed the vacuum pump, no leaks, changed the IWE solenoid, pulled out both locking mechanisms, tightened crossmember, checked everything from the hours of research I did on the internet. I cannot find the problem. I don't know what else to check. Front axles free spin and lock when they are supposed to. I'm at the end...

I got a 2003 5.4L Auto F-250 Super-duty CC yesterday and noticed it needed newer/new tires. I found some today and got them put on. I looked when the tires were off and all the tie rods, brakes, etc looked good. After leaving the tire shop the check engine light came on, I drove about 10kms on the hwy and it seemed fine then I got into town and made a stop.
When I was leaving there to go home I heard something that sounded like a chain dragging for a second then when I braked at lights the truck started jumping kind of so I pulled over and everything still looked fine. So I drove another 5kms and it was fine except for 1-2 lights it happened again, the brakes would squeal when stopping.
Then when accelerating from a light the truck would shake and make scraping noises until I hit about 30kms per hour, this happened whenever I heard the squealing at the few stops I had to do at lights. Some lights I stopped at and it was normal. The tires that were on the truck originally were mismatched, different sized and smaller than the stock size. The ones I put on are all the same set, and are 265-75-R16. what this could be?

I've got a 2016 250 6.2l and am getting a popping sound coming from the transmission area. the following is what i have figured out so far. the noise is made just before a complete stop, just as the tranny down shifts to 1st and can be felt through the manual floor shifter 100% of the time and heard roughly 90% of the time. sound ranges from not audible to loud and is random in how loud it is. the only way it does not do this is if i come to a stop in neutral or i go slow enough as not to have the tranny shift out of first from my last stop. the only other way is if i do one of those long, slow rolling stops. truck only has 6600 miles on it. i will be taking it in at 7500 for first service and have them look at it ...

In the last few hundred miles of driving, I notice there is a strange noise coming from what appears to be the front end of my truck. It sounds similar to a buzzsaw or a power sanding tool whenever it comes in contact with an object. The noise starts at around 30 mph, stops from 55-60mph, and starts again around 65 mph. The truck rides and drives normally and there doesn't seem to be any metal to metal contact noises or clunking and the hubs dont seem to be hot to the touch. I was thinking improperly balanced tires, wheel bearing, or front carrier assembly. What it could be? The noise just suddenly started and I was wondering if I should keep driving it?

My dad just bought a 2001 F-250 Crewcab 4x4 w/V-10. 72,000 miles. Anyways i noticed a small almost exhaust leaking sound on the test drive. I had the dealership put it up on the rack so I could see the underside. I noticed that it has the famous broken manifold bolt. So I kinda wrote it off on that we would have to get that fixed soon. Anyways the noise hasn't gotten worse just now noticing it that it has set times when it happens.
It happens around 25 mph then goes away then back at 45 mph, then goes away. I am having a hard time describing it. Almost like the exhaust is building up pressure then releasing it when it gets too high. But then I starting thinking transmission something since it kinda has a delayed shift when the noise happens.To clarify I am not saying it anything to do with the torque converter. I am just rolling to find out what is going on.

So after this weekend's hurricane my 2011 f-250 started to making a noise when I accelerate. I don't know if water got in some where. But there's no MIL light coming on.

Long story short, I need to replace the box on my 2008 F350. Do the boxes from '14-'15 models line up? I know the fuel door is different, but is the rest the same?

I have an 08 f350 lariat with the 6.8 with 66000 miles. A month ago took it to the dealer with a plugged catilityc converter. All covered under warranty. Got the truck back, starts great when cold including 18 degrees the other morning. I drive 7 miles to work, shut it off and restart, it acts as if the starter is struggling to turn the engine over. Once it cools off, starts fine again. I took it back to dealer, they replaced the starter. No change. Took it back again, they replace battery. Cranks a little faster, but you can tell it's still struggling. It always starts, I'm just wondering how it will be when it's 80 out and in pulling my 9000lb camper....

A bit annoying. 2008 F-350. When the truck is cold there is a creaking feeling I can feel through my foot. It usually lingers while the truck is warm but eventually goes away. It's in the actual pedal. This may be a stupid question but is there anything that can be lubed under there ?

Have an 08 f350 xl and was looking to put oem foglights into the bumper where mine has the block out 's, guess what I am asking is if the wiring is already there as it was on a different vehicle I owned ,basically it was a plug and play ,have only had the truck for a week and with the hours I'm working I really haven't had a chance to crawl under and look for the wiring.

Truck is 08 f350 lariat with minor issues. Both seat heaters don't get hot. Click is heard under driver seat. Both dash lights come on. No heat. Steering wheel fan control won't turn fan up. Turns it down fine.
PO put aftermarket HID with ballasts and bulbs and factory light housings. Factory housings scatter light and they are waaayyy bright. Can't drive anywhere with out blinding someone. What aftermarket projectors will work with HID set up I already have?

2008 F350 6.4 diesel. I have the listed truck in the heading, my #9 fuse which is for the interior lighting, lighted running boards and it is a 15a fuse, keeps blowing as soon as I touch the fuse to the fuse box to replace it. I have look at all the map lights and interior lights and can not find any thing out of the ordinary, all of these light were working fine, also my cruise control and the back up sensors stopped working and they are not on the same fuse and the other components that are on the circuit with the crule and back sensors still work, I know that this is a lot of different things but hate chasing electrical ghosts...

This has been beaten to death but all the old threads I read are for 2011 to present SDs so I wanted to make sure I can add these to my 2008 before I spend $ on the switches. Anything I should look out for on the install? Once they are installed I would like to add front and rear strobes along with a roof light for plowing.
