Ford F-150 - 1997-2003 :: 1999 V6 4.2L - Rear End Shudder / Vibration
I have a 1999 F-150, 4.2L V6 with 206,000 miles that recently developed a rear-end shudder/vibration. According to my door jam axle code (27) and the axle tag (3 37), I have what appears to be a conventional rear differential, even though most of my research would indicate this rear-end is for the F-250. In any case, and based on other online research, I changed the differential oil with a 75W-140 synthetic and added 4oz of a friction modifier. Now the vibration appears to be worse. It primarily vibrates when taking off from a stop, whether turning or not.
I have felt the vibration at speeds up to 60mph, but it is more noticeable at lower speeds. The vibration also seems to diminish after driving the truck for longer periods of time, particularly if at highway speeds. In other words, when I drive to and from work, which is about 30 minutes each way of mostly highway, the vibration is barely noticeable once I exit the highway and slow back down to 35-40mph. When feeling the vibration, if I decelerate, the vibration immediately ceases, but starts again when I accelerate. It's not as noticeable if I accelerate harder, but I generally don't do that. The gears inside the differential didn't have any noticeable wear, chips or slop/play. What may be plaguing my usual trouble-free F150?
Ford Aerostar :: Brake Vibration And Shudder By Loose Joints?
I was wondering if brake vibration and shudder (all the way up to the steering wheel) could be caused by some loose joints and bushings in the front end suspension (like ball joints, tie-rods, etcetera).
Is it normal to grab a hold of the outer tie-rod end and to be able to twist it a bit? I have a vibration problem when braking, but I am thinking it has nothing to do with the brakes. I am thinking it is something abnormally loose on the front-end suspension.
Ford F-150 (2009-2014) :: 5.0L Torque Converter Shudder / Vibration
Been doing a lot of reading about shudder/vibration on the 2011+ F150's and it seems to all center around the two piece driveshaft found on the longer wheelbases and more during take-off than other times. I have an '11 5.0L 4x4/auto with the 145 wheelbase and the 1-piece aluminum driveshaft and am experiencing a shudder in 3rd gear primarily, most noticeable during light acceleration with medium load (like gently accelerating up a slight incline).
When this is occurring I can see the tach needle fluctuating just slightly (maybe 50-150rpms, just barely bouncing) but I have no check engine light and the only time I have take-off shudder is under hard acceleration which feels like axle hop (which isn't too rare on soft leaf springs with 360hp engines!).
Anyways, this 3rd gear shudder is very soft and nobody has noticed it that has rode in the truck with me, but it sure feels like the old AODE/4R70W trans would when the fluid was getting old and the TC started to shudder during "soft" lock. 5.0L? Certainly could be a miss, though power is good, mileage is great and no CEL is lit...
Ford Excursion :: 2002 - Shudder During Braking?
My 2002 Ex 4x4 developed a shudder during breaking. Today while trying to jack it up and put on jack stands. My 2 3/4 ton jack was too weak/short to lift it up to put on stands. I am using 6 ton stands just to lift the front.
So have to get new jack. Keep in mind I don't have a ton of cash for new jack. What size are you all using to get your ex up on stands?
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.

So I just bought a 2004 Ex 4x4 4wd with only 50k from a dealer. While test driving the truck would shake/shudder when braking at 50-70 getting worse if you were going faster, as a condition of the sale they said they would look into it. They did and said it was the tires?? They balanced and rotated and did and alignment. Are they correct? the tires are BFG AT 33x12.5x16.5 on aftermarket rims.

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 Excursion :: Shudder Under Braking - Brakes Or Axle Wrap?
So Ive got slotted rotors with Hawk pads up front. I put them on a while back, pads are probably getting to the end of their life. Rear brakes and rotors were done by the dealer recently. X code springs up front, stock springs with RAS in the rear.
Under quick, semi-hard braking I get some heavy shudder, not sure if its from the from or the rear. I had been thinking it was probably the brakes themselves, and planned on addressing the fronts soon. But then I read something around here about axle wrap under braking, and am now wondering if that's the cause. I am pretty sure that big rubber cone on my rear springs is gone, and I read that that is what prevents axle wrap.
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 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.
View 6 RepliesFord Excursion :: 2000 - Truck Starts To Shudder With The Cruise Control On?
I just recently bought a 2000 excursion 7.3 diesel. I'm new to diesel but learning. So far I've installed a new drop in filter in my airbox. Cut out the plastic behind the grill for cold ram air into the intake. I've done the FPR mod and cleaned out the exhaust back pressure tube. And last but not least I installed an Edge Evolution 2 programmer running stage 3 with timing advanced 2 degrees. Nothing else to the custom settings other than what stage 3 provided. Here is my problem. On the freeway at 65-75mph cruising with the cruise control on, the truck starts to shudder. I suspect my TC lockup is going out but not sure. So I wanted to test it buy installing a manual lockup switch. So I installed the switch running a wire from the plug going into the transmission on the purple with yellow wire using a saddle tap to a switch to part of the dash frame under the dash. Went to test out the switch and nothing happened.
As y'all and other forum's have described I should feel something and the od light should start flashing. I get nothing. Tried testing the switch and my ground source and everything tests out fine. Tested the saddle tap. Its fine. Tested with the switch on and using a meter to check ohms at the tap to the frame of the truck I'm getting 8ohms. I would think there shouldn't be any resistance because its a dead short but that's what I'm getting. Am I connected to the right spot on the transmission or should I move the tap to the plug under the brake master cylinder. Could my TC lockup solenoid be going out and that's what's causing the shudder and why the manual switch doesn't work.

View 8 RepliesFord Excursion :: Transmission Will Shake And Shudder At Lower Speeds And While Idling
I have a 2000 Ford Excursion with multiple transmission symptoms, so here goes.
The problem doesn't occur until after the vehicle has been driven approximately 100 miles as far as I can tell. At that point, I'll start to notice smoke coming from underneath the vehicle caused by the transmission leaking fluid onto the exhaust from the front of the transmission. At lower speeds, and while idling, the transmission will shake and shudder. It's not noisy or that extreme, but definitely noticeable.
I've also noticed on occasion there is a loss of power at higher speeds when the vehicle is in 4th or 5th gear. This mostly happens when trying to accelerate to pass on the highway. The transmission sounds like it downshifts, but the hard I push the gas pedal, the less power I have. If I push down far enough, the RPM's begin to drop. I've noticed that after I let the vehicle sit turned off for a couple of hours, it begins to work properly again, but it only lasts until the transmission is hot again.
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.

With my car sitting, out of gear or clutch in, I rev the engine to say 4 thou. As the engine decelerates I get a perceptible vibration or shudder. It feels like an out of balance. In gear, accelerating, no problem. In gear, decelerating, no problem. And it doesn't happen all the time. It does, or doesn't do it hot or cold.
View 10 RepliesCamry :: 2002 V6 - RPM Specific Vibration / Shudder On Acceleration
I have a 2002 Camry, V6 1mz-fe with 110k miles, recently developed a vibration which only occurs on acceleration, consistently noticeable at 2100-2500 RPM during acceleration. Acceleration above or below this RPM range is smooth otherwise. Coasting and braking are smooth. This vibration has never happened on the car before, which has been smooth all 110k miles prior.
The vibration was initially pretty bad, felt through the car, steering wheel, floor, and seats. I have since replaced both CV axles and wheel hub bearings, with some improvement. Also got new tires and wheels are fine. I replaced a bad dogbone engine mount at the top passenger side a few thousand miles ago.
Other considerations at the moment include bottom engine mounts, since my dogbone went out before. Other Google search suggestions include spark plugs, exhaust pipe bracket, transmission mount(?).
What could cause such an RPM specific vibration/shudder?
