Ford 7.3L Power Stroke (1999-2003) :: Front End Clunking Sound Going Over Parking Lot Speed Bumps
Jun 9, 2015
I went to check out a '03 7.3 SD the other day. It didn't seem to have a lot of surge when I accelerated to freeway speeds. Kind of lazy feeling. Didn't smoke out the back though. It did have a front end clunking sound going over the parking lot speed bumps. I opened the oil fill cap while it was idling and it blew a plume of vapor/oil about 9' high like a steam engine puffing. Held my hand over it and got a oil wet palm after just a few seconds. I'm hesitant to drop any $$ on it.

I've had a rattling/clunking sound from my front left wheel recently so I jacked up that corner. As soon as the tire elevated off the ground the bottom fell inward. I could easily push the top of the tire inward and pull the bottom of the tire outward. Does this lead to a bad hub or bad ball joint(s)?

So my '01 E350 has been fine but tonight when I went to start it I didn't get a WTS light and the SES light was on and there was a weird number on my PHP Hydra that looked like r5 ? This happened a few times back to back so I tried starting it and it just cranked and cranked. Wtf? So I started pushing the button on the chip and all of the sudden I got the WTS light and the hydra flashed, now the chip was on tune 10 instead of 5 where it was when I parked it. I should also note that during these episodes there was a fairly loud clicking/clunking sound coming from the drivers front under the hood when I toggle the key on.. Sounds like maybe a relay? Louder than I recall ever hearing.

2001 ford excursion 7.3l diesel.
So I tried to go to work today but the truck said no. it started out fine then out of no where it felt as if someone slammed on the back brakes engine still revved up like normal just didn't want to go. speed dropped to 20mph then i heard a clunk. after that it was fine until it hit 20 mph again. it did the same thing again.
So I got mad at it thinking the trans went out gave it the beans and it shifts into all gears but did not feel like it had power. i did pull over and check the fluid looked a little orange. when got back in the truck i did notice the od off light blinking?? drove the truck home was shifting fine but hear this awesome sounded like a hand grenade rattling around underneath. when i got home notice fluid coming from the bell housing(out of the bottom).

What this clunk could be?? in my truck in signature, 2003 F350 CCLB 4x4, 4" lift. its only low speed, on very light bumps. really does it when the truck flexes, like turning into an elevated driveway or something. driving me absolutely insane the last few months. it sounds like its coming from right under my feet
-removed front shocks and drove
-removed front sway bar and drove
-front wheel bearings are new and tight
-front leaf spring, rear upper shackle bushings are new (thought that was problem..no)
-front leaf springs and bushings are new, although i suppose its possible to have a bad bushing already
-removed traction bars and drove
-removed front track bar and drove, but going to try this again.
-all cab mounts look ok
-took out cab mount under drivers foot, and cut down the metal piece a little...read about it on another thread on here. no change
-made sure my gooseneck ball couldn't rattle
-steering box is new...thought that was it
-steering shaft is solid
-transmission mount bushing and crossmember feel tight
-lubed front driveshaft slip joint and it doesn't have any u joint play
-rear shocks seem ok but haven't removed them yet
-fuel tank is solid
-rear driveshaft has new carrier bearing and u joints, all is tight
-exhaust is not hitting anything
-u bolts all tight, spring bolts are tight
As you can see, I've been through damn near everything. my only thoughts right now is a possible bad cab bushing, or bad leaf spring bushing...as it sounds like its right under my feet. and when you flex the truck, it makes all sort of popping and clunking noises. i had the truck on my buddies lift and we went under it for an hour yesterday looking around with no luck. only thing i found was a bad traction bar bushing but we removed them and it still does it..
Most noticeable at the end of the video...it sounds exactly like a bad sway bar bushing but that's not it...

Clunk in the front end when going over speed bumps? That is the only time I ever get it, never on bumpy roads or anything like that just at speed bumps. It seems to be louder on the drivers side but I am pretty sure its on both sides. I never noticed it until a couple speed bumps were installed along my normal route, but that could be because maybe I never drove over them previously?

I had to raise the car a bit to clear the apr turbo outlet pipe. Raised a little too much and was hearing a clunking sound pulling into my driveway or speedbumps, etc. Contacted HR and they said the coilovers have an operating range and to lower them a bit. So.. i have about 3/8" of thread left on both fronts and my (not so scientific measuring method) fender/ground is 24" vs 26.25 stock as measured on a stock gti on my dealer lot. I still have a ton of thread to drop the car (about 1.5") as seen in the picture below. The issue i have is what the spring looks like. It rides fine in my day to day commute so its not noticeable but looking at it, it looks collapsed??

I have a 2001 Escape XLT, when driving thru a parking lot or otherwise at slow speed and hitting bumps, I can hear a clunking sound from the right front tire. Its especially bad if I drive over cobblestone or on a dirt road. Could this be the CV joint? Ball Joint? How can I tell what it is?

I just noticed today while driving to lunch today that at lower speed and tons I can here an intermittent hissing sound. But as I speed up and build boost it goes away. Not sure what could be causing this sound. it sounds like it could be some sort of pressure leak or exhaust leak I have no clue...

'01 Taurus with an occasional rattle/clunking sound coming from the front end when going over bumps. Took it to the local shopping center auto. service dept. (probably 1st mistake I know) They say the only thing they could find was the RH CV boot was bad and was probably the source of the noise. Doesn't sound right to me since the boot is rubber and what I hear is more of a metal sound..what I was thinking possibly a suspension link or tie rod end. I know what a bad cv JOINT sounds like and it's nothing like this. Now if the CV boot is bad I don't mind to replace it, but I don't want to spend the money if it is not going to solve the problem. I've never heard of a boot making noise before.

I recently (1month ago) rebuilt my entire front end. The only things that were not replaced are track bar, steering box, front driveshaft, and sway bar bushings. I'm having the same issues that I had before the rebuild. It just feels like the front is is on basketballs. Hopping and vibrating at any speed or rpm. On a smooth road or on the highway it feels like I'm hitting bumps that aren't there.

When I turn on my fan for the AC or vent or heat, it works just fine on the first and second settings. When I move the fan speed to the third and last speed, I hear this sound that sounds like the blower fan is hitting something. I turn the speed back to the lower two settings and noise goes away. Sometimes I turn it back to the higher settings and the noise actually will go away but most of the time the noise is there.
I pulled the blower motor out yesterday and set it to where I can turn it on while out of the compartment and I didn't really notice a noise. I wonder if the noise is there but I am just not hearing it since it is not enclosed in the compartment? I also noticed there is a crack in the fan where it mounts to the shaft starting at the shaft and extending out one direction and also 180 degrees the other direction. Thoughts on if the motor is bad or just the fan? Or even something else that I may not be seeing?

I have a clunking noise from the right front suspension when going over bumps. I've replaced the Strut bushings that were collapsed, the control arm bushings that had play and the noise is still there. There is no play in the links. There is a slight noise in the sway bar bushings when struck with a rubber mallet. I hate to keep replacing parts chasing down this noise.

Thats the sound coming from I think the front left area and the rate is proportional to speed. It only occurs at slow speed from about 5 to 15 mph and it seems to only occur for about 30% of each rotation. I plan to jack it up and check tire wobble or if the sound occurs during free spin. Any other things to check?

I know lots of you say these stock Rancho's suck, but I'm wondering if it's just the ride that improves? I have some clunking under the truck when I go over "sharp" bumps that normally I would say is something loose or maybe a bad ball joint...except I have it in the rear as well. Is that a symptom of these stock ranchos? I don't mind the stiff ride, it's the noise that's bothering me.

Tonight on my way home I noticed a slight creaking sound, coming from front driver side, opening the window it was more noticeable. So when I got home I have tried to locate the source, it is the same with or without the engine running & you can hear it by rocking the steering just a little left to right. It sounds like a dry bush, I had my good lady rocking the wheel while I climbed underneath but couldn't pinpoint it, so I climbed up on the fender with my weight on the radiator support & the battery cover, when she turned the wheel the sound was almost gone but as soon as I jumped off it was back! I then tried rocking the truck from the driver side fender & the sound is there but not quite so pronounced, Any other way before I spray everything with WD40 (don't know if you have that over there but it usually quietens things like this!) There is no play on anything anywhere & the truck has only around 32k miles.

I have something clunking in there (at 35 MPH on up) that's been driving me crazy for about 2 or 3 years. I may have finally caught a break by way of an intermittent symptom I didn't catch before. I just pulled into work and hung a hard right to do back-in parking. As I backed up slowly, I felt a clunk about every 6-12 inches of travel. I ran out of room before I could keep testing, so I pulled forward for another go at it. Symptom gone! I tried a few more times without getting a repeat, so I just parked after entertaining the masses with what they must have thought was a tough parking job for me.
OK... so 6-12" is nothing close to a wheel rotation, and I'm not inclined to thing it's a full driveline rotation in reverse... but I still can't rule out a funky U-joint. All U-joints were replaced about 3-4 years ago, and the driveline was completely rebuilt, straightened, and balanced. Rear end rebuilt two years ago. Front bearings replaced 2 years ago. Front hubs replaced about 18 months ago. Wheels and tires replaced last fall. Transmission replaced 5 years ago, flex plate replaced 2 years ago. The only spinning thing untouched is the transfer case - which is a chain and gear affair. I know from vast experience how stretched chain and grooved gears behave - but I don't know when that thing is spinning or not.
Could this be a tired transfer case getting grabby?
On the front bearings: I lost the vacuum seal on the front right last winter, and that hub gets warmer than the other side. I have planned to get that looked at (I have no time to jerk with it), but I wonder if I dropped a shiny Timken and that's what I feel in the wheel... and if that could be the clunk. I didn't feel the clunk in the wheel as I backed today, that one was more of a fore-aft clunk.

I have a 2002 f250 7.3 and the belt is rubbing front edge of the belt and making a whipping sound at 65 mph. Have replaced tensioner, idler, water pump and a/c bearing & pulley.

I have 1999 F350 7.3 Crew Cab 4WD. I took it on a 4 hours trip towing a trailer to haul a small tractor on it. after 3 hours of driving, I started hearing grinding and metal chewing sound coming from the front axle or close the wheel hubs. It was awful, terrible, ... you name it!!! I had to continue or I will lose the tractor I paid for already. The sound was coming for 1-2 seconds each 500 feet or so. It never stopped or changed. I pulled over to see what's going on and found the following:
1. Left shock is leaking badly
2. Right locking hub is gone (not sure if the truck had one before). I bought this truck last year, but I never had to use 4x4 and I know the 4x4 motor by the transfer case is missing and the nipple on the transfer case is set to the 2wd position so the front drive-shaft does not turn.
I took the front shock off and continued to drive without it, the noise did not go away.
I pulled over again and this time I noticed that the dust cover on each end of the front axle is missing too. I have never worked on these axles before, but I jacked one side, and sure enough, gear oil was leaking from the other side. I took the plug off the front differential and stuck my finger in it. I felt a creamy brown-greenish stuff in the differential. The consistency is like mayonnaise or thin peanut butter. I put the plug back on and went to pick up the tractor because I did not want to miss it fooling around with the truck on the highway.
The truck made it there and back (almost 5 hours total after the break down). The sound never stopped every 500 to 1000 ft.
After getting home safely, I took the other locking hub off, and took it for a test drive. I did not hear the noise, but now my right brakes are locking.
I took of the wheels and saw that the retaining snap ring (C clip) for the front axle on the right side came off by hand. I took the washers behind it off. Took the calipers and brackets off. I have never done front axle rebuild. I am not sure what has been damaged and what's still good.
Right of the bat, I know, at least, I need 2 shocks, one brake caliper and pads.
My questions are:
1. Is it possible to take the front axles off on both sides and make it 2wd for now until I have the money to rebuild the axle?
2. Could I use the same hubs? or they are most likely damaged and how to tell?
3. How to tell if the differential is damaged/needs rebuilding?
4. How to tell if the axles/spindles are damaged?
5. Is there a step by step tutorial to rebuild the axle with all seals, bearings, ...etc? How hard is the job for a hobbyist? I do most of my repairs myself, and I was lucky at 36 years old, I never had to rebuild a differential.
6. What else I might have damaged in the process of driving it that long with the noise? How do I tell if I did?

I bought a 2000 F250 V10 Super Cab. Oddly after a few weeks it has grown on me. There has been a clunking noise out of the right front over bumps. I traced it to a bad axle bearing. The u joint moves up and down about a 1/2 inch. Besides pulling the hub/bearing assembly out and removing the axle are there any surprises getting the old bearing out?

Looking for some tried and true fix to make these parking brakes hold just a little? Winter coming and with a six speed would like some resemblence of a brake....short of a brick in the drive. I have adjusted.....no luck. New cables ( thinking maybe stretched)..no luck. Shoes are new. Did notice levers where cable attach look to be worbled out.....gonna try to tighten that are up a little to see if that works but.
