Ford Excursion :: Growling Sound When Let Off Go Pedal
2 weeks ago I had some poorly installed spring shims start to slip out, the last day I drove the truck before parking it to wait on parts to arrive I started to hear this sound as I let off the go pedal. New shims were installed yesterday but I still have this sound. I had never heard it before the day mentioned above. It only lasts for a second or so and only when letting off the gas at above 30 mph, at very low speeds and let off gas no sound. Here is the link to a really short video, hopefully you can clearly hear the sound twice in the clip, I am doing 40 mph and feathering off the gas. Phone is laying in cargo area so there is no picture, just sound. What is that sound?

Ford Excursion :: 2005 - Drive Line Vibration - Rear Springs Sag?
Since I bought this '05 Ex, I have had a driveline vibration. Not bad mind you... just barely noticeable when I let off the gas going 50+ mph. I had my local Ford dealer change the Ujoints and it worked a little.
I just installed Firestone Air Bags on the rear axle. I put 20 lbs. of pressure in them and it raised the rear exactly 1 inch (I measured before and after). After the air bags were in and pressurized and the rear lifted 1 inch, I took it for a drive. WOW! The driveline vibration is completely gone. Smooth as glass.
Question that I need opinions on from those who have more experience with an Ex than I do: Did my rear springs sag enough to cause a driveline vibration? And did the lifting of 1 inch put it BACK to stock height so that the driveline is now correct?
Ford Super Duty (1999-2016) :: Strong Vibration Like Shuddering / Growling And Rumbling In 2WD Intermittently
My 2000 f250 4x4 V10 5spd manual with LSD and 63k mi gets an intermittent but very strong vibration like a shuddering, growling, rumbling in 2WD. The 1st time it only lasted about 1 second. It had been making a swooshing noise that sounded like front left wheel bearing for several thousand miles before this, so i replaced bearing assembly even though it turned smoothly.
After that, It still made the exact same swooshing noise and after a couple miles at 45mph, it had the strong vibration/shudder that lasted about 3 seconds. I stopped and locked the hubs manually. The vibration happened again in a couple miles, so seems like it's not the needle bearings in front stub shafts or locking hubs. On that last occurrence, the vibe went on for 5 seconds, felt the same with clutch in, and went away only after truck slowed down to nearly a stop. I've driven it about 6 mi total since the 1st occurrence.
Front right Wheel bearings feel smooth. I unbolted the driveshaft support bearing and it spins smoothly. The front u-joint maybe had a tiny bit of play, all bolts tight. I didn't check the nuts for yokes, but it didn't look like yokes had any play. Drive shaft slip joint moves smoothly. No up-down play at pinion shaft input into rear diff and output from transfer case. Rear diff oil was full with a little bit of silvery sludge on the magnetic filler plug, maybe 1/10 of a cc, no metals slivers or chunks. I raised the rear wheels and ran 5th gear 2WD at idle (~30mph) and touched a 4' listening stick to the drivetrain components.
The only odd sounds were from the rear differential. It sounded like a bad bearing with random crunches and thuds mixed in with the normal whirring. Crunches and thuds were loudest at front of diff housing. I blocked one wheel and repeated in 3rd gear. You could hear noise like gears meshing (noisy spider gears? maybe was LSD clutches?). The differential was warm after 5-10 minutes, with the hottest area being about 3" from the front of diff, just before the housing widens.
So, I'm guessing the pinion bearing is bad and the intermittent shudder is the bearing race spinning in the case when bearing seizes.
Ford - Explorer :: 2005 - Grinding / Growling In Front Differential
I have some pretty bad grinding/growling in the front of my 2005 Explorer XLT 4-door. It is ABSOLUTELY NOT a wheel bearing. The noise seems to be coming from the front left wheel, and you can feel it when turning the hub by hand. I've changed that hub twice now (took a chance that the first one was defective), but neither made any difference. Both were torqued to 184 FtLbs per spec.
I took the outboard end of the left front cv shaft out of the hub and turned it by hand, and something at the inboard end felt crunchy. So then I pulled the shaft out and checked it over, and both sets of splines and CV joints are good. Axle shaft bearing in the differential looks good too---rolls well and no visible damage to the rollers. I'm thinking that it's got to be something in the front differential like a carrier bearing. The odd thing is that when I drove it with my Chassis Ear tool hooked up underneath, the noise was picked up at the left front knuckle, with nothing really audible from three different points on the differential case. I'm stumped on this.
Is there any safe way to drive the vehicle with the front CV shafts pulled? I'd like to isolate the front diff to be sure it's the source of the noise.
The noise does quiet way down in right turns, but the FR hub bearing was pretty quiet with the Chassis Ear hooked up. The noise starts at 20mph and dissipates above 45mph. Not like what the bad bearings on my Escape did...those just kept getting louder.
Are these Explorers known for front diff weaknesses? How can I find out what gear ratio I have, in case I decide to replace the whole unit (a used one is half the price or less than the rebuild quote I was given by a local shop).
Ford - Explorer :: 2005 XLT - Growling That Sounds Like Coming From Front Left Wheel
I have a 2005 Explorer XLT with the 4.0L V6 and AdvanceTrac.
I've had a worsening growl in the front end that sounds like it's coming from the front left wheel. I can feel it in the steering wheel, and the sound goes away when I turn the wheel right of center. Center (going straight) or leftward steering, and the noise comes right back.
I changed the wheel bearing today, and there is absolutely no change in symptoms. Turning the CV shaft back and forth by hand, something feels kind of "grindy." It is the same at any point along the shaft, which has me worried that the bad bearing is in the front differential.
Nissan - Altima :: 2013 - Growling / Vibration When Temp Drops Below 40 Degrees
When the temp drops below 40 degrees I get growling/vibration. When I took it to the dealer the service supervisor test drove it. He then checked with one of the mechanics who said they all sound like that. I called Nissan. They told me I had to resolve the issue with the dealer (who is now out of business).
View 5 RepliesAvalon 2005-12 :: Humming / Rumbling Or Growling Noise Starting At About 25mph+
Wife complained about the noise coming from the front. She said it sounds like an engine noise. I took her car for a few days noticed the noise starting at about 25mph+ (near the driver side). Tried to put the engine in N and rev it, while driving, pretty such it is not the engine.
I do notice the noise is getting a bit louder today compared to last week...Did some google search and "it might" be the bearing. Just wonder what to do next. My wife doesn't want to drive it at this time....so she took my truck today
Chevrolet - Cobalt :: 2005 - Steering Wheel Started Making A Loud Growling Noise And Vibrating Really Hard
So 2 weeks ago I noticed that after 30 minutes of driving on the highway my steering wheel started making a loud growling noise and vibrating really hard! When I hit the brakes it got worse but got better as I slowed to 30 mph. It doesn't happen all the time and not right away, only after a while of driving and the dealership says without codes they can do nothing...
View 7 RepliesNissan - Vibration - Frontier :: 2005 - Roar And Vibration That Keeps Getting Worse Over Time
I've got a 2005 Nissan Frontier that has a roar and vibration that keeps getting worse over time. It happens as long as the car is rolling, but is the loudest at around 35 and 65 mph. From the driver seat is does sound like it's coming from the front passenger side. A few months ago I was driving across a curvy road and when I got home I could smell hot brakes. I checked, and the front passenger side caliper was stuck. I rebuilt the caliper, and that seemed to free up the wheel, but didn't fix the roar. I drove a couple more weeks and found the caliper stuck again. So this time I replaced it. The wheel has been fine since, but the roar is still present. After a while I figured it was a bad wheel bearing and replaced that too. But, that didn't work. I've also taken it to a shop and had them check the alignment, to which they said it was fine. I'm still racking my brain trying to figure this out.
View 5 RepliesFord Excursion :: Vibration Between 40 - 55 MPH
2000 V10 X vibrates from 40-55MPH when OD is on. When OD is off, significantly less vibration - very minor between 40-50MPH. Bad OSS?
I had codes for misfires on #4 and #8. I replace the spark plugs and coil packs on all 10 cylinders and codes changed to P0354/P0358 - primary/secondary circuit. Wondering if that is contributing to it.
I did the full reset process on the PCM. Codes cleared throughout the entire process. But once I stopped and restarted truck, codes came back.
My thinking is to get a replacement PCM first. I haven't done a lot looking over the wires to #4,8 coil packs. cursory look they seem to be fine.
Ford Excursion :: Front End Vibration At 55 Mph
My new to me 04 X has a fairly bad vibration that starts around 55 mph. At about 60-65 it sort of goes away, but not completely. The wheels are 20" F-250 wheels ( 2006 ) with spacers/adapters. These were on it when I bought it. I had the wheels re-balanced and checked the ball joints. This made no difference.
This is not what I would call the death wobble, just a bad vibration in the front end. The steering wheel does shake/vibrate a little, but so does most of the truck while it is doing it.
Ford Excursion :: 2003 - Vibration At About 60 MPH
At about 60mph I start to get a vibration through the vehicle. Its not in the steering wheel but the seats have a little vibration and you can see the child seats start to shake some. Stops above 80 and doesn't get real bad, just a little shimmy.
I rotated and balanced the tires with only 6k on them and its no luck. Where to start looking next: driveshafts, u joints, sway bar, etc.

Ford Excursion :: Vibration / Shudder Between 45 - 55 MPH?
On our trip to Daytona this weekend I noticed a vibration/shudder between 45-55mph. Above and below that range it doesn't happen. Dont feel it in steering wheel or pedal. Does it in both 3rd and OD. Got under truck and driveshaft doesn't move at all. Just got those new tires put on a couple weeks ago. Don't remember this vibration before that.
Just checked tire pressure - front right 48 psi. All the rest have about 45 psi, would that do it? I have a shudder in brakes from stops above 45 mph I'm assuming warped rotors, could that do it?
Ford Excursion :: 2002 - Vibration At 70 - 75 MPH
I have a newish to me 02 ex with 7.3 psd. It had a gradual vibe at 70-75 mph that i brushed off when i test drove it. I figured it was tires, old vehicle, etc. Fast forward to a couple months later, it still happens in the same range of speed but now is bad enough to shake your coffee in the cup holder. Vibes happen regardless of throttle position, OD on or OD off, etc etc. It is entirely speed dependent, occurs on 2 lane roads when I go that fast, or on the interstate. Ive even kicked it into neutral on the interstate and the vibe is till there until it gets to 69, then it goes away.
I feel the vibe in the seat of my pants, barely in the steering wheel (I feel like what little is in the steering wheel is transmitted thru the frame, etc.) So here's what Ive had done thus far, and the vibe is still there, unchanged:
1. had wheels and tires balanced and rotated
2. had driveshaft balanced
3. had rear driveshaft u joints replaced
4. took rear driveshaft out and ran it up to 70mph on jack stands (no vibe)
5. pulled both rear axles one at a time to see if wheel bearings were OK and if vibe was there with axles out, and vibe was still there.
so i finally took it to a driveline shop and had them go through the rear end, thinking it had to be something there. They called me and said your carrier bearings are toast, so I said go ahead and rebuild the rear end with new timken bearings and new gears, etc. So they do that and I still have the same vibe at 70-75 mph. I'm at my wits end here, the shop totally expected the rear end rebuild to cure it.
The only thing I haven't done is remove the rear driveshaft and drive it in 4h to see if i can replicate the vibe there. I hate to spend anymore money on this just trial and errorring everything. That leaves the transfer case and transmission to be the only things causing the vibe as far as I know.
Also, the vibe occurs around 2k rpm, but only when at that speed. In lower speeds, at 2k rpm it is smooth as silk.
Ford Excursion :: Vibration Occurs Around 60 - 70 MPH
I have been chasing a vibration that occurs around 60-70 MPH. Had all the tires re-balanced and checked the rest of the suspension and narrowed it down to the rear driveshaft.
Took the X to the driveshaft shop and he checked all the joints and suggested that I grease the slip joint as it still was original as delivered. Here's what I did.
Removed the rear bolts and dropped the rear of the shaft. Cut off the factory boot clamps. Marked the shaft so it could go back in the EXACT way it came out and removed the rear of the shaft with the boot intact. While the rear of the shaft was out I checked the joints and found them to be perfect.
There was no real grease to speak of left, just the factory ford blue. Filled it and the splines with moly grease and re-installed the shaft and boot. Clamped the boot with nylon ties (per his suggestion). No vibration any longer. Thought I would post this up as a quick tip.
Ford Excursion :: Vibration When Coasting Down From 110 - 115 MPH
So I'm used to the vibration coasting down from 110-115mph or so, I would mitigate it by applying light throttle. Recently it started coasting in the 75-80 range, then 70-80, and now it does it just plain cruising in that range as well. Nothing below 65, and nothing above 80 (coasting, cruising, or under load).
It's definitely a mechanical vibration, tires are fine, wheels are fine, wheel bearings are new... Thinking driveline u-joints? Don't have the money to throw parts at it unless they're the fix. I've consulted Christina's analysis chart and this is the only thing that makes sense so far.
No other symptoms anywhere else except those ranges. U-joints are, as far as I know, OEM originals. 276k miles seems like a hell of a life for them, especially with the abuse they've seen in the past 75,000.
I need to crawl under and give things a shake and wiggle, current condition is unknown. Left for a road trip to meet the wife's ex so he can have his time with his son, and the X was so bad at the aforementioned speeds that we turned around and swapped vehicles. It was worse this morning than it's ever been and I wasn't risking catastrophic failure with a zero emergency fund.
Ford Excursion :: Slight Vibration Above 50 Mph
I have had a minor vibration above 50 or so mph(by speedometer). Installed a new driveshaft and corrected the pinion angle to near perfect. I have OEM 4.30 gears and 33.4" tall tires. I had to retune motor/PCM and one of the options while installing the new tune was tire revs per mile.
I input 620 and pressed on. Now my slight vibration is gone. Even at a corrected 70 mph it's smooth. I'm a little baffled, as I do not understand how a tire diameter correction in the PCM could affect the drivetrain?
Ford Excursion :: Grinding And Vibration Goes Away At Constant RPM?
After driving for about 15 minutes, once it is warmed up, at acceleration & low rpm's, there is a vibration, mild grinding noise. Once you get to mid-range and up on the rpm's, it goes away. When cruising down the highway at normal speeds and a consistent rpm...no noise. Idling at, and taking off from a stop light, I get the noise. The longer it is driven, the more noticeable the noise is. Possible torque converter?
View 8 RepliesFord Excursion :: 2002 - Light Vibration Right At 70 Through 75 MPH
On that note I have a 02, 7.3 Limited with 195k on the clock. It has had this problem since I owned it. I have put about 20k on the Ex since I bought it. Right at 70 mph through 75 mph I get a light vibration.
I does not matter what I do, on or off the gas in neutral the vibration is there until I exceed or drop below that speed. The vibration is really annoying on long trips and I feel on edge the whole time waiting for something to break.
Its not strong enough to rattle change or the mirror but is enough that I can feel it and hear it. I had the wife drive and seems like most of it is coming from behind the drivers seat area.
I really don't want to start throwing parts at the problem. The guys at the shop said its a truck and thats what they do. Needless to say I found another place to have work done.
Here is what I have done so fare
New tires (Bridgestone Revos E)
Upper lower ball joints
Balanced front and rear drive shafts
Replaced the front Drive Shaft CV joint - what was not cheap
Lubed the slip joint on rear drive shaft
Ran the truck without the rear shaft and the vibration is almost undetectable but, still there.
I had it up on a lift and checked for play in all the wheels, found drivers side rear to have a little bit of movement. - Could that little bit of play be causing my issue? I am going to take the rear wheel bearing apart this weekend if time permits to investigate that. No leaks on rear axle.
I have not put new u-joints in the drive shaft as the shop said they were fine. Only the front CV joint has been replaced. Should I go ahead and just change the rear u joints out?
Also all fluids have been serviced and no metal shavings on the plug magnets front, rear, tranny, or Transfer case. I have no lift and suspension is all stock. I want to put a lift on but issue more then likely be compounded with a lift.
