Ford Excursion :: 2001 V10 - Bad Vibrations When Hit A Bump
Oct 23, 2014
Continuing to find little easter eggs with my new to me 01 v10 excursion.
This issue is a bad vibration that feels like it's coming from the middle of the truck. It starts when I hit a bump and usually goes away when I hit another, but not always. At first I thought it was the road, then the transmission, but now with it starting when I hit a bump, I'm thinking a U-Joint on the driveshaft.
I considered the front axle u-joints but it doesn't matter which wheel I hit the bump with, be it a pot hole or man hole cover or seam in the road.
I'm not sure where to start. I'm doing the trans flush tomorrow and dropping the transfer case to see where that's leaking, so I'll be under there to try and figure it out.

4450 - Literature Program 09L02: Customer Maintenance Reminder
Some owners of certain F-Super Duty 250/350 4x4 vehicles have experienced severe steering and front wheel vibrations and oscillations after traveling over a bump or dip in the road. As a result of a study with NHTSA regarding shimmy, Ford sent a Customer Maintenance Reminder letter to owners back in March of 2009. In addition, Ford agreed to send reminder letter to owners.
Although there is no service action required by the dealer, customers will be informed if after setting the tire pressures on their truck to the Ford specified levels, they believe the vehicle needs additional service, to contact their local Ford dealer. Letters will be mailed starting the week of 12/09/13 and may result in increased customer service inquiries.

I bought this truck a little over a year ago and have put almost 30,000 miles on it. When I bought it, it had a clunk from the front end, but only when I went over a significant bump. It was most pronounced when I, for example, hit a speed bump at an angle and the body rocked back and forth. It's steadily been getting worse and now it's fairly concerning. It happens on pretty much every bump now. Additionally, I've developed a fairly significant shimmy under braking and a vibration over 65mph. I got into a fairly scary shimmy when trying to slow down as I was going down a mountain a few weeks ago.
The other day I started getting a grinding noise from the front right. It goes away when the brakes are pressed. I don't know if the grinding noise and vibration/shimmy are related to the clunking or if they are the result of a separate issue. I have plenty of brake pad and rotor on all corners and there is no perceptible play in any of the front end components (wheel bearings, ball joints, tie rods, shock mounts, etc.). I suspected the leaf spring bushings, but I supported the truck by the frame and still got no noticeable play when jerking things around by hand.

A few weeks ago I hit a large pothole while going around a slight curve at about 55 mph. I heard a loud pop and the truck jumped to the left. About a week later I starting noticing some vibrations. It happens when I'm going more then 35 or so and when I hit a bump or unsmooth surface and it will keep vibrating until I hit another bump, the other way to make it stop is to slow down to less then 20. I can feel the vibration pulsing less as I slow down utility it stops meaning it's definitely speed related not engine related.
So I took it to the shop. The found the passenger side front (the part that hit the pothole) shock was leaking, upper ball joint was toast (a lot of play) and the outer tie rod was loose (not as bad as the ball joint but bad enough). And the bump stop I installed about 7 or 8 months ago was gone.
I picked up the Ex yesterday after having everything replaced (did the lower ball joint as well, I figured might as well once it's all taken apart). While driving today, the video ration is still there. So I pulled into the nearest gas station and took a look at the front end. I noticed the driver side hub is still locked (even though it's on auto, probably have a leak in the vacuum line somewhere). So I pulled both auto hubs just for the heck of it and kept on driving. Now I barely feel the vibration.
So the question is, is my front differential causing the vibration? I don't believe it's the hubs, when it was at the shop I personally (and the mechanic) shook the wheels right and left and up and down and besides for the play in passenger side wheel from the ball joint, everything else seemed tight. I recently did the u joint on the same wheel and the stabilizer bar bushings. This is my work vehicle so when it really slows me down when it's in the shop.

The truck, 2001 X, 7.3l diesel 4x4, with a couple of enhancements. (Link to original post of truck... [URL] ... )
Here is the issue, on this mornings drive to work the front end started to make a lot of noise. The noise (which was minimal) was originally thought to be caused by a front wheel bearing that was just replaced, Today it got really loud, and the steering wheel started to shake as well.
Pulled over, disengaged the hubs and the noise and vibrations went away. First thought would be that the U-joints need to be checked and possibly/probably replaced. That would be the simple solution. However, if it is not the u-joints, what else could it be?? Issue with the front differential???

I have posted several times about my 03 Ex and it's driveline vibes- mainly highway speed and when slightly on the gas... Took it to a local 4 wheel drive shop that specializes in lifts. They jacked it up and I ran the X up to highway speed with the rear in the air. It was amazing how rough it is, even at 55mph. I hardly feel it in the vehicle at that speed while driving.
Anyway, they felt the vibration but where it is coming from. They said pinion angle looked fine and since I have a retubed driveshaft and rebuilt rear, they ruled that out. The owner has an 04 with a 6 or 8" lift and 37's and seems to know about Excursions.
I then took it to the local Ford dealer and had the service manager drive it. He strongly feels it is gear mesh with the ring and pinion. I am not totally convinced as the rear is quiet, gear wise. For that matter, my slip yoke has quite a bit of torsional slop, likely as much as the backlash on the ring and pinion but the driveshaft shop said that it is acceptable.

I had a 7" icon installed with reservoir shocks installed. Rides pretty good driving unless I hit a dip or bump. When either of those are steep down or up I have a very hard hit. Could the shocks not have enough travel? I am at a loss to explain except it is a pretty hard contact. It looks like the shocks have about 3-4" of shaft exposed on the shock. Unfortunately I do not think I can post pictures yet.

Just experienced the teeth jarring "thud" from going over a speed bump. That was bad. I want to fix the issue right now for cheap. I plan on doing the full blown V/B mod swap out later, but don't want to buy new rubber when my current is nearly new. Dealership wanted ALOT of money for replacement leafs. This is just a temporary temporary measure to stop the slamming.
Front
Option 1: 2" Lift Shackles
Option 2: 3" Mini-Pack Leveling Kit
Rear
Option 1: OEM F-350 4" blocks
Option 2: Generic 4-5 Lift blocks
I really like the shackles for their price. Flip side though, I feel the mini-pack would firm up the ride a tad. My old F-250 rode like a truck, and the X just doesn't.
Are the factory front shocks long enough to support 2" of extension without breaking? I really didn't want to mess with the rear suspension, but she sits pretty level right now and I'm not a fan of the Bulldog look.

Had the ex up on a lift today as I plan on swapping out the shocks and noticed that the front bump stops are completely gone.
Could this be contributing to the harsh bumpy jarring ride I have?
I don't quite understand what they do as they just appear to be bolted to the frame and the next piece of metal they can hit seems far away from where they are positioned?

While driving the other day I heard a loud bang under the ex. went back and found the rubber bump stop on the drivers side had rotted and fell off. After inspecting the passenger side it looks like it is about to fall off . I dont mind spending money to keep my equip in proper running order but I dont want to be taken advantage of doing it!

The right rear door on my X is rattling when I hit a bump. The door is not closing tight enough. I can reproduce the noise by just pushing on the door. I don't see any adjustments that I can make.

Just purchased a 2000 V10 Limited with 117000 miles on it. Absolutely love it....just have a noise that is bugging the crap out of me. My husband doesn't think it is a big deal, but I would love to find out what it is without dropping 60 bucks at the dealer.
Whenever I turn a corner that is a tad bumpy it makes a bump type sound. It usually happens only when one side is going over the bump. It is pretty loud. IT will happen also when I am going down my dirt road without turning but when one tire goes over a bump the truck kind of shifts from side to side and the sound starts.
We have thought it could be the shocks or maybe the springs making that kind of sound. My husband is clueless and he knows alot about vehicles. I just hope my description wasn't too vague.

2001 Toyota Sequoia LTD, 115,000 miles, replaced cal & discs & steering rack bushings early last year. Lately after 20 to 30 minutes of hwy at 70mph touching the brakes to shave off 10 to 15mph causes heavy vibrations from the front brakes like the wheels aren't round. No lights, ABS or VSC, no noise from the ABS unit. Same in 2WD, 4WD, VSC on or off. Touch the brakes from 70mph and it feels like slowing/stopping on washboard??? Tech checked, no codes present . Brakes function fine around town as does the ABS & VSC, alignment good.

On my 01' the bottoms of the bump stops are completely gone. Rusted out to the point to where the rubber stop on the front lower control arm (if the truck bottomed-out) would go right thought it. The rubber stops are fine.
This pic was taken from below the control arm looking up. You see the rubber bumper and just above it is the stop (some what triangular shaped). the bottom is rotted away... Are these replaceable or repairable? They seem like they are welded to the frame.

I am experiencing what feels like a "bump in the rear" when initially starting from a dead stop. It feels like a car behind me tapped the bumper or that the truck "hunkers down" first, then moves. Tranny seems fine also. Once moving, there is no problem whatsoever. There atre no noises, leaks, or other symptoms. Also, when coming to a stop, it feels the same way just before the truck completely stops. If I drift forward a little, then apply the accelerator, it does not "slip" or hunker down.
Took it to the dealer and they claim that they can't find anything wrong and may just be the suspension releasing? The truck does this whether loaded or not?

Toyota Tundra 2001 v8 4wd. sequence of events as follows . Changed rack and pinion ,tire rods, had aligned no problem. 135000 miles, on it so it was time to change ball joints upper and lower, and struts on front, and brake pads, aligned, now when I hit a bump or hollow the truck feels like its out of control like it goes side to side too much, on level road no problem, changed shocks on rear, but no difference, new bushings on rack and pinion same thing, could it be control arm bushings? or shocks on front are faulty, how could I check? all parts bought at a well known auto parts store, its driving me crazy, last thing tires scream a little going around corners, like you hear if someone is going too fast, but I am not.

Early 04 f three50 (kids thought it would be funny to take the three key off keyboard) with a bad vibration once over 60 mph. Thought it was carrier bearing which was worn but i still replaced it. The u-joints are tight. Not sure where to go next. It is a long bed but these arent normal vibrations. Tires are fine .

Was pulling a trailer with a large tractor and had switched the 01 7.3 Ex with 300k miles to 4WD with the switch on the dash. All was fine till I tried to switch back to 2WD.
Then it sounded like I hit some rumble strips a few times and then a constant shake/rumble till I switched it back to 4WD Hi and all was fine as far as the rumble strip feel.
Also, I tried to Manual maneuver the hubs and they are unmovable, but that has always been the case since I got it at 140k miles. I rarely use 4wd so this is a whole new arena for me.

My '01 Excursion gets a vibrating noise between 70-75mph. I've located it to the 2nd row drivers side seat. Only does it when it's in the upright position. I can hit the seat and have it make it briefly. But I can't locate the cause.
