Ford Super Duty (1999-2016) :: Rear End Shudder / Vibration After Lift Installed

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?

Ford - Mountaineer :: 2001 - Quick Vibration / Shudder From The Rear After Acceleration

I now have an '01 Mountaineer with AWD and the 5.0. I have a strange vibration that only seems to happen when I accelerate as I get on the highway. I get up to speed and just as I let off on the throttle I get a vibration/shudder from the rear. Almost as if I ran over the rumble strip on the side of the highway. It's a short grrrr, then it goes away.

Ford F-150 - 1997-2003 :: 2002 - Slight Vibration In Rear End When Cruising Down The Highway

Noticed my 2002 F150 had a very slight vibration in the seat / steering wheel when cruising down the highway at 60 MPH.. Very slight, but was not there 2 weeks ago.. It seem to get a little worst as the 2 weeks progressed. Got all 4 tires balanced and rotated... no luck...Took both rear wheels off-- no problems with tires -- checked bearing clearance-- pushed and twisted on driveshaft yolk to check pinion bearing... nothing found......... last resort was drop back end of driveshaft and check U-joint.. It was tight and dry. Put drive shaft in 12 ton press and pushed out the u-joint bearings. Very dry and joint pins were starting to spall....... I mention this because I had checked " clearance" and "slop" and had "no noise" before removal... Truck has 139K miles on original u-joints .......... Something to keep in mind. Eventually it would have worn to the point that it was obvious, but in the first stages of failure, you just get small symptoms.

Ford F-150 - 1997-2003 :: Vibration And Thudding In Rear End When Braking / Low Speed Squeak

I recently bought a 2003 F150 sport Scab 4x4 with 75k miles from a Ford dealer with a 4.6l auto. we didn't notice it when we test drove it but it has a squeak when going 0-10 mph in forward or reverse. The story goes a week after getting it home we started noticing a vibration and thudding in the rear end when braking so I take it back to the dealer (50 mile trip 1 way) and when I get there the drivers side rear rim is 30 degrees hotter than the passengers so the tear it apart and find the e-brake was dragging so they lube it up and tell me its good to go. I made it around the building and now I feel it dragging iddling around the parking lot and it is still squeaking so I take it right back in.

Long story short after going through this 2 times that day and bringing it back another day they replaced rear pads, calipers, roters and the hoses going to the caliper and tell me its good to go. Well it no longer had the dragging feel and I had to drive through DC traffic so I beat feet for home and on the way noticed its still sqeaking. I call them and they tell me to put a thousand miles on it and maybe the pads just need to wear in (??). so I took a road trip and 1.2k miles later it still squeaks.

I have tried to tell them it may be the u joints (after searching on here I learned that I am taking it back tomorrow and going to try and get something done but they are still saying its something to do with the brakes and probably won't do the u-joints. Normally, they are filling up the gas tank every trip up there and its all been under warranty (gonna see about getting the warrenty extended tomorrow due to this problem has been ongoing since we got it). Should I just let them run their own course and keep making trips back and forth?

Ford - Explorer :: 1997 4x4 - No Running - Shudder In Rear Tire - Front Never Spin?

My Explorer is a 1997 with the control trac 4x4 system. It's only purpose in life at the moment is to plow snow and its been doing that quite well. I typically leave it in 4lo all the time. Every once in a while, I will switch it to the other modes to ensure they are all working.

Today I was plowing and it looks like I'm getting nothing, or next to nothing to the front wheels. There is some shudder if the rear tires begin to spin, but the front never spin, or lock up. I can feel/hear the transfer case shift when I change modes between auto/4hi/4lo as I usually do, but the front wheels just are not doing their job. All three modes are not driving the front wheels.

The transmission was rebuilt a few years ago, and it's shifting fine. I'm suspecting the transfer case. Only my OD light is flashing, but it only does that once in a blue moon. I plugged my code reader in and it could not read those codes. I was able to clear the light though.

Ford Super Duty (1999-2016) :: Vibration / Shudder When Coming To A Stop

Driving 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.

Ford F-150 - 1997-2003 :: Tranny Shudder In OD Doing About 20 - 35 Mph

I have an 01 4x4 Ext cab with the 5.4 auto. It just started to shudder in drive doing about 20-35 mph, it quit when I turned the OD off and has not come back yet. It also jumps in and out of OD while running highway speeds, kind of like hitting a bump or something like it. The shudder was in about 10 degree temps and not fully warmed up and the jump happens whenever I am at speeds around 60-75.

Ford 7.3L Power Stroke (1999-2003) :: 2001 - Clunk / Vibration In Rear End

I recently purchased a 2001 excursion 7.3 after driving it for a while I have noticed a significant clunk and vibrate in the rear end. I have read a lot of people saying it could be the slip yoke needing lube which I intend to do but most are saying that their clunk is at start and stop.

Mine is between 30 and 60mph when I let off the accelerator I get a clunk followed by a vibration and when I get on the accelerator it is just the clunk. Does this sound like the slip yoke to yall or am I looking at something more? I have tried turning the drive saft and there is no play in it at all.

Ford Super Duty (1999-2016) :: Shudder / Vibration When Starting Out From A Stoplight With Some Acceleration

I just bought my 2015 F350 long bed Platinum a month ago, and the first trip with my 12,000 lb. 5th wheel had a vibration when starting out, but only from a stoplight with some acceleration or an incline, not at level slow startup.

Ford F-150 - 1997-2003 :: Shake / Shudder When Accelerating Around 45 - 55 MPH

My trucks been doing something weird. When accelerating around 45-55 mph, a couple seconds after it shifts to 3rd, it does a weird type off shake/shudder. Feels like I hit a small bump in the road. Also when coming out of a cruise to accelerate, it will Make a very violent clunk and then speed up. I'm thinking it's a problem with my torque converter but my mechanic says transmission and my buddy says rear end lol. I dropped the pan and there was some shavings but nothing huge and it was the first time it was ever dropped. After 90k miles.

Ford Super Duty (1999-2016) :: 2003 - Chatter Or Vibration Coming From Rear End

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 ?

Ford Super Duty (1999-2016) :: 2015 F350 - Takeoff Vibration Or Shudder Under Load

My 2015 F-350 Super Duty has a noticeable vibration between 5 and 15 mph when accelerating with my 5th wheel. The 5th wheel is heavy--around 14000 pounds. The pin weight is heavy--around 3000 pounds. The Owner's Manual says on page 191 "When driving with a trailer or payload, a slight vibration or shudder may be present due to the increased payload weight..." (This was brought to my attention by my dealer.)

Seeing the thousands of F-250 and F-350 Fords pulling 5th wheels out there on the road, I wonder how many have this "slight vibration or shudder" and what they have done about it.

Ford F-150 - 1997-2003 :: 2001 - Shudder And Surging Upon Acceleration

When I first bought my 2001 f150 a few mos ago there were no problems but I did notice once in a while it would give one little shudder when id accelerate. now all the sudden it shudders after around 20 mph all the way up to whatever the speed limit is. Then it smooths right out until I have to accelerate again. if I punch the gas and kick it down it will clear up but then it feels more like a surging going on.

I had the cruise set at 70 the other day and I had to slow down to merge to around 50 and when I hit resume it really started shaking bad and the service engine soon light flashed on and off for a few minutes then went off and hasn't came back on again. I took it to advance auto and no codes showed up. they said its probably the torque converter but after reading multiple forums I am not so sure now.

Ford F-150 - 1997-2003 :: 1998 - Shudder / Hesitation At Certain Speeds

Just bought a 1998 5.4l F-150 Lariat. 136,000 miles.

Question about the overdrive button on trans handle. When I push the button, I don't see any light turn on (or off) and I don't feel any change in the gear ratio or increase/decrease in rpm's. I assume since the button in there marked "overdrive" that the vehicle in fact was equipped with it. Could it be a bad button, fuse, or ?

Also, it just started the shudder/hesitation at certain speeds that I see a lot on these threads. Seems like that is a coil issue as the description in many threads is exactly what I am experiencing to incl the rotten egg/fuel odor. However, it started the same day (not same time, later same day) I decided to push the overdrive button while checking out all the things on the truck.

Ford Super Duty (1999-2016) :: 2003 F250 - Vibration At All Speeds And In Rear End When Braking

My 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.

Ford F-150 - 1997-2003 :: 4R70W - Shudder At Speeds Between 45 And 50 When Trying To Accelerate Mildly

99 F150, 4x4, 5.4L, 4R70W trans.

I am experiencing a shudder at speeds between 45 and 50 when trying to accelerate mildly - it usually occurs after slowing down from a higher speed.

It is similar to the bucking that occurs when you do not downshift a manual trans.

I am guessing that it is the torque convert clutch staying locked or the tranny staying in OD too long. The shudder will go away if I give the truck enough throttle to downshift or simply push the overdrive off button - which forces it to downshift to drive.

What is the probable cause?
