2003 in sig. when going around corners slow I can feel and hear a chatter or vibration coming from what I think is the rear end. I am running amsoil 75/140 in it and added some friction modifier. Do my clutches are shot and making noise or do I need to add more friction modifier ?
View 7 RepliesOk, I've seen a post or two about this issue of rear end chatter on the super duty But not that many so I am going to ask a question here and now......what causes/allows this to happen and what purpose does it serve? also, does it cause any damage to the gear head? or any other part of the rear end?
My truck tends to do this from time to time when I am plowing snow (only when backing up, or at least so far) and I really can't relate it to condition other than maybe the fact that pushing snow may cause the gear oil to get hotter than normal driving and thins out and causes this?
I have a bad wobble/vibration coming from front end i think i replaced hub locking hubs u joints truck dont feel safe at all took it to ford they say its normal no way its not just starting doing it few month feels like the 4x4 is in use when hitting bumps when driving if you go slight left or right it seems too make act up more.
View 2 RepliesMy 2003 Ford F250 V10 seems to have a vibration, sometimes at all speeds and sometimes at freeway speeds. I replaced front hub assemblies and ball joints and rear calipers last year. When braking i have a vibration in rear as well, which I think is from uneven rotor but can it be causing my vibration? Also sometimes I can smell hot brakes from the rear.
View 2 RepliesI have been having some brake chatter for awhile now. I have changed pads, changed rotors, rebuilt both front calipers, flushed all my brake fluid, and made sure my slide pins were good and free. I have noticed some weird wear on the new front rotors and was wondering if it was normal or not. On a different note, I am having to replace my parking brake pads. When I had the axle out I looked in and saw a bunch of gunk.
View 12 RepliesDriving into work this morning, I came up to the first stop sign before I get on the "freeway" and noticed a weird vibration. As I slowed to stop I could have sworn it felt like the engine was being lugged, the same feeling you get in a manual when you try to come to a stop without using the clutch. I thought for sure the engine was going to die. The engine RPMs dropped to about 800-900 RPM and once I got to a complete stop the RPMs went back to normal.
It seemed to do this every time I came to a stop. Could my torque converter be locking up and not releasing as it supposed to causing the lugging sensation I'm getting? The truck accelerates fine and idles fine once stopped, but when slowing I get that weird vibration and maybe the lugging sensation is just in my imagination and has nothing to do with the engine.
I do have a vibration from a missing wheel weight, but that's usually felt at about 34-35 mph. In addition, I also have a bit of a brake vibration when slowing down quickly, such as when slowing quickly from 65 to turn off the highway onto my local road, but this is a completely different vibration.
When I bought my 05 350 dually it had been wrecked, the rear diff was under the bumper and most of the rear suspension, including the back part of the rear drive shaft was in the bed of the truck. I have gotten everything back in place, and have driven the truck for a few weeks, but I knew I was going to have to replace the ujoints because there was visible damage to one of the caps. I have also had a vibration at about 45 mph. I had no way of knowing how the original driveshaft was oriented at the slip yoke so I went with best guess. Now in my research I read that if the driveshaft is not put back exactly in the same position vis a vis the slip yoke it will be out of balance.
Also if the drive shaft is dropped it is scrap, and if I have any lift on the truck {it had 4 inches when I got it} the whole thing will shake itself to pieces. Most of the answers to other drive shaft questions talk about taking things to a good driveshaft shop. No such thing here in the vast stretches of My state. I am pretty much on my own as far as building or repairing this thing. Is there any way to determine how the shaft was originally oriented? I also have some damage on the end of the yoke and will have some trouble getting the ujoint apart. Is the shaft now junk? And if I get an ebay replacement, how do I tell if that shaft is in the right orientation?
So I'm getting a mild to severe shudder depending on load and acceleration rate from stop to 10-15mph... It's worse if I'm on an incline...This has started since having a lift installed...I'm guessing it has everything to do with pinion angle...right?
1999' F350 7.3L 4x4
Crew Cab Long Bed
Trying to figure out my rear pinion angle should be. I still have vibration in the truck around 65-70 mph and sometimes around 80mph if i go that fast. I checked my rear axle last night and its at 8.5 degrees on top of the pinion snout is that correct???? And i forgot to measure the rear driveshaft angle but i can do that after work when i get home. Truck is a 2004 ext cab short bed 4x4...
View 7 RepliesOn my way to see my folks and I started feeling a vibration like driveshaft or wheel bearing between 45-55 mph then at about 75 then BOOM! Pulled over and found a pool of ATF thought my stock 4R100 just bit the dust but looking at it the fluid is coming from the front driveshaft at the Tcase. My hubs are unlocked and my ESOF is in 2HI but I assume my tcase was locked. Also since the tcase is probably screwed I'm goin to do the 271 with manual hub swap, how hard that is?
View 10 RepliesI've got a 02 SD v10 4x4 with Warn hubs and 97k. Bought it a couple months ago and I've noticed a vibration coming from the front driver side. Symptoms are that of a bad wheel bearing; vibration that increases with speed and not RPM, seems to lessen on left handed turns (weight transfers from driver side to passenger side) and gets worse on right turns. Also the truck seems very twitchy and hard to keep straight on the highway.
Snowed the other day so I locked in my warns (just in case) and I instantly noticed the noise and vibration almost went away entirely except for on the freeway around 70+ mph. Also noticed it seems less "Twitchy" on the freeway. Mind you the hubs are locked in but still in 2wd. After doing a little bit of reading some were saying this is a sign of bad needle bearings and not the entire hub.
I haven't jacked up the tire and checked typical movement in a bad wheel bearing. I know my way around vehicles and 4x4's pretty well...
I have a 02' 250 4x4 with 250000 miles on it. While driving between 55 to 65 mph there is a roar and vibration that seems to be coming from the rear. I have about 35% tire tread left and have had the rear tires balanced and it still does it. Having issues with drive shafts unbalanced or rear ends?? I am not sure where to start....
View 1 RepliesSo I had a strange vibration coming from the drivers side wheel intermittently. Only when the hubs were in Auto , by locking them it would not happen. With hubs in Auto when it occurs switching into 4H made it stop immediately.
It would occur after small bumps and sound like driving over a rumble strip. I figured it sounds like a needle bearing in the hub going wonky and just replaced the entire sealed unit. So that should be it right? Nope.....
The vibration has changed tone and sound but still occurred after a slight bump to the right Driver Side tower. It now is a much deeper tone then before.
I made sure everything was reassembled correctly and tight. I notice however that if I remove the ESOF lockouts to rule them out it still occurs (no lockout in at all ) .
I can move the outer DS stub shaft quite a bit with one finger when the lockouts are not installed. Which would explain that why when the lockouts are installed and I lock the hubs it doesn't occur as the end of the stub shaft rides in the lockout.
I haven't changed the outer axle seals , but they really didn't look shot. It appears as if the play in the axle is coming from the pumpkin.
Side note: I took apart everything and cleaned it , there was mud, crud, dirt and water throughout the hum to and into the lockouts. see pix below for the mess and carnage. I cleaned and lubed everything up.
I've got a 2003 350 7.3, with the zf6, approx 225000. I've been chasing a vibration that can be felt in the whole truck for quite a while. Feels like a wheel bearing danm near shot. But after replacing both wheel bearings and making over the whole front end it didn't go away. So I replaced the clutch and throw out bearing cause it was getting bad anyway. The vi ration is still there so I checked the harmonic balancer and it was bad so I replaced that. Still no dice. I know that it's coming from the trans, you can hear it in when jacked up and running in gear. Shifts fine in all gears. But the vibration/ clunking is there in all gears and it's getting bad. It feels like a bearing going out. Could it be input shaft bearing or pilot?
View 14 RepliesI have an '03 F250 Super Cab, 7.3L PSD, 4WD. I've started getting a large vibration between 40 and 60 mph. Started after driving on the PA highways towing a trailer with a car and hitting several deep pot holes.
I have had the wheels balanced, rotated, balanced a second time by a different shop and had them perform an alignment - Still No change.
The garage I took it to said the hubs were shot so I had them replaced - supposedly with Moog, lifetime warranty hubs. Still - No Change.
The tie rods and steering linkages are a year old, so unless something was damaged (visually, they look good, and feel tight) it probably isn't them.
I replaced the ball joints around 80,000 miles and now the truck has 155,000 miles. They appear to be ok, with maybe just a little movement in the Passenger side upper.
If there is any movement at all in the ball joint, will it cause a vibration?
I plan to rotate my full size spare through all 4 corners this weekend to eliminate the possibility of a bent rim.
I have another set of ball joints and seals on order which should arrive next week. Probably next weekend's project.
I have a 2006 f-250 with 5.4L 3valve engine. I was worried about my variable valve timing system because my engine sounds pretty rough and I hear a lot of valve chatter. I know that low oil pressure can be a big problem on these engines. Here is a pic of my oil pressure gauge. This was taken while the truck was warm while parked.
View 14 RepliesI have a 2003 f350 4x4 lariat lifted 3 inches on 35s. I am getting a a roaring and vibration in the right side of the front end when I make a hard left turn. Don't get it going straight or right and get it more in the throttle. My mechanic and I thought it was the front right hub bearing/assembly. So we replaced it and the noise and vibration is still there and now there a shimmy in the steering.
View 14 RepliesI had a pretty good clunk going on and found the passenger tie rod was shot. The rest of the steer components looked fine. Fixed it and still get a nice bunch of clunks. Went over the steering again with someone rotating the wheel and didn't notice any crazy movements. The drag link twisted a bit but the joints looked solid compared to the tie rod which was completely shot.
So I decided to dig into it today. Looked again and nothing. So I took it into my back yard to drive over some humps left from stump grinding. Clunk, clunk, clunk. I stuck my head out the window and wouldn't you know it the sound seems to be coming from the rear! Took a pry bar to parts like the sway bar links, shocks, etc.... can't detect anything. Maybe a u-joint? Gotta dig in I guess.
Also my rear springs creak like nothing I've ever heard. Dirt roads it's just creak, creak, creak.
My 99 super duty v-10 has 227,000 miles. It was a former UHaul unit but seems in good shape considering the abuse it's probably had! I recently started hearing a clattering sound coming from the rear.
Not just turning but in straight line. Very loud even at 2-3 mph, more pronounced in deceleration. I can best describe it as someone shaking a metal pail with about a half dozen lug nuts in it.
Previous threads point at the limited slip. I called the Uhaul after sales desk and he right away said put some friction modifier in and do figure. Eights in the parking lot. I did and The sound is still there.
One poster said the factory LS is garbage and not worth rebuilding. They mentioned the TruTrac as a good replacement and I guess I'll investigate that further.
I replaced the steering gear box in my 06 F250 CCLB 6.8 over the weekend with a reman Cardone. The old gear box had what I can best describe as a chatter/binding if you rocked the wheel back and forth, that's gone now. I sucked out as much fluid as I could, then filled the reservoir several times while the fluid ran out, what came out was very cloudy and gritty, guessing the old box was chewing itself up.
Can't seem to find a straight answer - what fluid SHOULD this have in it?
Sounds like I should have used Mercon, looks like I grabbed Type F instead. Could that cause the steering effort to be extremely light? I mean like ridiculously light, tip of your pinkie barely touching and turning the wheel light?
I have a '03 F350 that I can't seem to solve the brakes vibrating when applied. Replaced front rotors a couple weeks ago. I still have a vibration when I apply the brakes. What am I missing? I didn't replace the back rotors, but maybe I should have. On the passenger front, the inside pad was almost gone and the outside pad was in good shape. I greased the pins before I replaced the pads the last time, but the inside still wore much faster. I also blew out the rear brake line last week and spent Saturday bending a new line and replacing that so the brakes were bled when I had to replace that. I don't feel the pulsing in the pedal, but the truck shakes pretty good when I hit the brakes. What else should I be checking if the rotors are new and the pads are new and the pins have been lubed and the brakes have been bled?
