Ford Super Duty (1999-2016) :: Noise Noticeable When Cruise Down The Highway
Sep 29, 2016
02 f250 SD 5.4 zf6 manual xcase ext cab long bed...
When I'm cruising down the highway it's most noticeable. 5th gear anywhere from 65mph+ I'll let off the gas and it'll make a "errrRRRt" until I press the gas again. I've recently installed new :
- Front u joints, ball joints, hub assemblies, rotors, calipers, pads
- Rear drive shaft u joints
- Front diff fluid
- Trans fluid
- Tcase fluid
- 4" zone lift kit
All of these things did nothing to effect the noise. it seems to be coming from between the clutch and rear shaft (either clutch, trans, tcase). I don't think it is a motor noise or suspension noise.

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?

When running up through the gears under normal acceleration I can feel almost a double shift in 5th gear. It doesn't occur using tow/haul so I assume it is the TC locking up. Everything else seems fine. Truck has 9k miles, mostly towing. 2016 6.2 ....

My current 08 duty was bought with what I believe to be a procomp 6" lift modified to an 8" lift. The 100 mile drive home after buying the truck showed a tiny "hop" in the rear. I ditched the 37s for some new 35s. Still a tiny hop, mostly noticeable while under a load like climbing a hill. I pulled the rear driveshaft and had it fully rebuilt with a new carrier bearing as well. Still gots the hop? The truck has a carrier bearing drop bracket but I think it may be insufficient for the lift.
The rear driveshaft still has a slight bend in the middle of where the two driveshaft pieces connect. Are the 2 piece driveshafts on your 8" lifted trucks sitting straight with each other or do they have this bend as well?? I am thinking if I get a bigger drop bracket it may cure this slight hop I have? Lots of lifted trucks where I live but they are dam near all shortbox with 1 piece rear shafts so I haven't been able to find one to compare. By the way, my truck also has pro comp rear traction bars..

I noticed a moaning from the front end a few weeks back and it seems to be slowly getting a little worse. It is only noticeable when I'm accelerating or maintain speed, but as soon as I let off the accelerator and start to decelerate, it goes away. Sometimes, when the truck hasn't been driven for at least a couple hours, I pull away and there is a really noticeable sort of "clunk clunk clunk" but then it goes away and it just moans. I can also hear some noise from the front end at highway speeds, but of course it is hard to hear much else other than engine and road noise from the cab. It's a 2003 F250 with a 7.3 and four wheel drive.

Did a 1600 mile trip and noticed that the cruise 2x would just shut off. Most of the time tho it ran fine. Every once in a while when I would stop for gas and turn off the motor the cruise would not come on at all when we headed back out. Sometimes when it did this it would not come back on till I shut off the truck and then restart. Other times it would work after 20 or so miles.
When it did shut off or not come on, I would try turning it on and off, mashing the buttons HARD, What to do? Or should I just take it to the dealer and be done with it?

02 E450 Super Duty V10, C class a motorhome, 29000 miles. Cruise stopped working a month or so back. I searched this forum and managed to fix it with the info provided. It turned out to be the pressure switch on the master cylinder, the recall had been done. I replaced the pressure switch and the harness with an aftermarket one from the local auto parts store. It worked well for about 200 miles, it knocked off again on our road trip last week. It was working on the road and we stopped for breakfast and it didn't come on again, no light in the dash or anything.
When I ran the internal diagnostics on the first repair all the lights would flash when the buttons were pressed and the servo would cycle through at the end of the test as it should, based on the diagnostic instructions. This time when I run the diagnostic test the light will flash when I first turn the switch on (holding the off button down) and when I push the on the button but will not flash when I press the other 3 buttons.
I have not been able to find a wiring diagram for this particular truck, I've found 6 or so but none of them match my fuse boxes under the hood and dash.
I have no trouble lights on in the dash CEL or ABS. I'm at a loss what direction to take from here.

I've got a '08 F250 XLT that the cruise control has become intermittent. It works most of the time but at times it will "go out to lunch" and not do anything. I've taken the controls from the wheel and didn't see any gummed up coke spills or anything there. It may not be anything but twice when it failed while on a trip I pulled over and shut the truck down. Started it up and the cruise would go back to working. Once I did this and it went back to working only to shut off in about 2 seconds but I was able to engage it again and it kept working. When it stops working there is no green indicator on the dash either.

My 1999 SD was originally a Work Truck without cruise. I'd like to add cruise of some sort (factory or after market), but also trying to keep the cost and difficulty factors low.
Have any of you SD drivers ever done this and if so, what you went through?

Suddenly my cruise control dropped out. With some investigation I'm pretty sure it's that sensor or switch stuck to on position. Brake light is on. Checked the brake system and everything works well. Fluid is full all 4 pads replaced 2 days ago. Plenty brake power.
The question is: how can I bypass that switch to get my cruise control back? I see 4 wires coming out of the switch: red, blue, green, red/orange, green/purple. How do I do it?

Been searching but can't find a clue. I replaced my steering gear box. Went fine, but after starting back up. My alarm goes off, my cruise or horn doesn't work and my air bag is giving a code 32.
Is there a ground wire or something I could of missed when installing the gear box?

Just noticed today that my cruise control on/off button is sticking. Push to off it stays pushed off, push it up to on and it stays up so i must physically center it myself. Is there a way to remove the button and take it apart to clean and regrease the contacts so it doesnt stick? Kinda dumb actually since i might have used it eight or ten times since buying the truck new....

Cruise won't power up. Tried entering diagnostics but did not get any flashes. By-passed switch on master cylinder, did not make any difference. Horn honks. Brake lights work correctly.

2014 f250 with 2500...My cruise went out on my new platinum. Cruise symbol comes on, goes green when I hit set but will not hold speed. I know this would be an easy warranty fix but here's my problem. My regular local dealer, which I bought my 3 fleet truck and all personal autos from didn't get this sale. In fact he was 5k higher then the dealer 120 miles away and I brought him written proof. He was very angry and down right rude when I nicely told him I couldn't pass up 5k. He told me that was just bad business by the other dealer and hung up on me.

2010 f250 cc 5.4 145000 miles. I bought it last fall have not drove it a lot. When using the cruise control and a load is added grade or hill in the roadway. It jerks hesitates or miss then cleans up and runs fine. When using the accelerator it does not do this. No codes.... Thinking about changing the plugs.

Just bought the 03 listed in my signature line, and I just found out that the cruise control isn't working, so started trying to troubleshoot anything obvious.
When I switch it on, I get no cluster light that the manual shows to be to the right of the brake light. When I turn the key to run, it never lights up, so am guessing the bulb is bad.
Can't see how a bad bulb would keep the system from activating, so am thinking I have bigger issues. I pulled the fuse panel, but the manual does not have a listing for speed control. Which fuse it is combined into?
Also need the skinny on how to change the bulb. Can I reach my hand behind there? does the cluster have to come out?
Last question. What is the most likely culprit for non functioning cruise? A module? Perhaps the switch in the steering wheel?

Came over the "mountain" tonight elevation is 1,054 (Snickers Gap) anyway cruise was set to 62mph and the truck kept downshifting. Got to 2nd gear about 5500 rpms and was trying to hold 62mph. I turned off cruise and it stayed in second and picked up speed still in second, I finally tried some braking and some acceleration with the gas pedal and it shifted up through to 6th. Truck has 6.2L and 3,300 miles on it. I wasn't really afraid of wrecking or anything but I was convinced it was going to redline in 2nd, it didn't but it was really loud. I was about 10-15 seconds from throwing it in neutral.
Additional info: I have driven this road for 14 years, with cruise control on in everything from a geo metro, (2) different 2010 f-150's 4.6 and a 5.4, ford escape hybrid, and many other vehicles. This is probably the 10th time I have taken the new F-250 in to the city and back it has never reacted this way before, but I have notice it downshifts more than I expect in other situations as well.
So is the downshifting what others are seeing?
6.2L Supercab, longbed 3.73 gears.

Our cruise isn't working, I've read through the posts here and tried a few things
2000 F-250 V-10
-First symptom was the cruise light would light with the ON button and go off with the OFF button but I could not set the speed with the SET button. Now the cruise light hardly comes on at all any more.
- I've run the cruise self-test diagnostics and all the switch presses passed with no additional light blinks. After the static test the speed control servo makes a sound but does not move the throttle at all.
-The horn works
-Fuses are good
-Truck was taken to the dealer several years back for the cruise update. The pigtail with the green label is installed at the master cylinder. I've disconnected both connections and sprayed with contact cleaner.
That's about it. What it could be or what to test next?

I was driving home from school last week and noticed my cruise control would stay set for 5 minutes or so, then slowly (over several minutes) lose speed. I've noticed it happen before, but very infrequently and usually if I stopped to use the restroom, when I started the truck back up it was fine. This time it continued to happen.
As I was getting nearer to home, I noticed that while I had the cruise set, I would hear a high squeaking noise in the dash almost dead center under the radio. Then , when I would tap the brakes, there would be a rattle. This would only happen with the cruise set.
Noise in dash - YouTube
Not sure how well the squeak can be heard, but the rattle is definitely audible. What the cause might be? Electrical, mechanical, are the cruise and the noise even related? Other than that, the truck seems to be running alright.
