I have a 2011 F150 ecoboost supercrew 6.5 ft bed. I have noticed a bad vibration/ grinding in the driveline, mainly after a long trip on the highway and coming to a stop and starting again. And it's noticeable at lower speeds. What this may be caused by. It seems like the rear end is binding but I have had the rear end checked and the level was good.
View 2 RepliesIt's NOT a truck. But my '97 Town car happens to use the same 4R70W transmission and 8.8" rear axle that the F150 from the same era used to use....
I'm troubleshooting what I first thought were bad pinion bearings in the rear differential. On the highway the car makes a shaking/growling kind of noise that fades in and out from 55 MPH and higher. Also when you're on the throttle there is a howling type of noise that comes from the rear of the car, the harder you're on the throttle the worse it is.
I got under the car convinced that my pinion bearings were shot, looking for the smoking gun. But I can't find any noticeable play on the pinion shaft of the rear axle. Slid on up to the front of the driveshaft and there's noticeable play on the extension housing of the transmission:

Any chance this is causing my issue, or am I in for some expensive rear end work?
I got my 77 ford truck w/four wheel drive half ton with a np435, 351M and i was wondering if a bad or worn bearing can cause vibration. i can feel it by the pedal when i accelerate from 50 to 65. I don't know if that's my trans or maybe the pilot bearing?
View 10 RepliesOn my 07' I bought it home mid AUG. It has been getting much worse to a point there is a rear driveline vibration at all speeds above 40 and up to 70. I used to change intensity whether you are on or off the gas, and would almost vanish if in neutral. However now it is all the time.
I cannot feel any play on the u-joints, the yoke has a little play in the xfer case but is is normal like on most other trucks I have owned, and the pinion flange is nice and tight. Could this be **tight** ujoints or the driveshaft itself? It looks rusty, but there are no dents on it.
Truck is an '07 F350 Supercrew, 8ft bed, SRW, 2wd. I bought the truck last month and noticed a low frequency driveline vibration starting at about 45 mph and is noticeable to about 65 mph. Feels like a bad u-joint. So I pulled the drive shaft (two piece) and checked the joints. They seemed find so I sent it to a commercial truck shop that does driveshaft work. Had the joints replaced and the shaft rebalanced.
Re-installed drive shaft and went for a test drive. No real change in the vibration. The hangar bearing seemed fine so it wasn't changed. Doesn't feel like a wheel out of balance. My experience tells me its a drive shaft.
I have a 15 F250 CC SB 6.2 4x4 that is suffering from a driveline vibration. Had the shaft checked for balance and it was off. It's a little better now but still there. Checked all the angles and they're correct. Also came up with a curious observation that all CC SB 4x4's have a slip yoke driveshaft at the transfer case while all the other trucks have the fixed yoke. This appears to be my source of the vibration.
View 3 RepliesI have a 2010 XLT, 85K, just started having a horrible grinding noise at start up for about 2-3 seconds, then gone. Going to dealer tmrrw. Multiple people said, possible oil pump hydraulics, ??????. Whatever it is, they say its expensive!!!!!
View 3 RepliesI have a 09 f150 with 160,000 on it. For the last couple months I was hearing an occasional buzzing sound from the engine compartment. Couldn't duplicate it while not driving. The buzzing sound has changed somewhat but it's follow by a grinding sound that seems like the hubs are trying to lock while in 2 wheel drive. I think the buzzing is coming from either the IWE solenoid or the vacuum check valve. My question is this. If I pull the vacuum line off the the solenoid and plug the line will the hubs remain locked till I can dig into this a little deeper. I was thinking that they would stay locked. I should still be able to shift in and out of 4 wheel drive correct?
View 7 RepliesI have a 1999 f250 SuperDuty with a nasty vibration That begins at about 70mph. The truck is an extended cab 5.4l Manual trans 4X4 with a one piece driveshaft (No mid bearing). The Vibration appears to me to be a driveline vibration that is speed dependent. It is the same in gear, out of gear clutch in or out. I have replaced the wheel bearings/hub assemblies on all four corners, completely rebuilt and balanced the driveshaft the driveshaft, removed the front driveshaft, put brand new tires mounted and balanced on all four corners, new clutch, had the flywheel turned and balanced, and replaced the transfer case output bearings. Pinion bearing feels tight and does not leak.
Also the Input in the trans felt tight when i had the trans out. The truck had the vibration when i bought the truck and still vibrates after i have done all of this work. i did not change the motor mounts because they looked fine. when i bought the truck the tabs on the extension housing holding the trans-mount to the trans were broken so i make a huge "exhaust clamp" to straddle the trans and bolt to the trans mount.
After driving the truck up north last weekend the truck seems to shake going taking of at lower rpm as if the motor mounts and trans mounts are bad. I guess my questions is can a bad trans mount, motor mounts cause this Vibration at highway speed. if so is there a way to fasten the trans-mount to the extension housing without replacing the extension housing. If not what else can cause this issue?
02 CCSB, and I have a vibration in my driveline that's starting to drive me nuts on my commute every day. I can feel it faintly starting at about 45 mph, whether the torque converter is locked or unlocked. The vibration peaks at about 60 mph and goes away at about 65+. My u-joints are all moog and grease them every oil change (about 120k on them now). At this point I suspect the carrier bearing, yokes, or even u joints but there's not much play. However the rubber around the carrier bearing is in rough shape and dry rotting. I'm curious if there's a test I can do to find the culprit.
View 1 RepliesThere is a grinding noise when i make a turn,when i straighten out it's fine,when i bought the truck in 09 i had a shudder problem but that was repaired by greasing the spline in the drive shaft. Truck has 59,000 and is coming up on the 60,000....
View 1 RepliesRecently had a coworker point out that my truck was making funny noises while it was backing up. It is a 2013 f150. It almost sounds like metal grinding to me. It does not do it while going forward either.
Have been underneath and can't notice anything out of place, although I'm not sure I'd notice if there was.
I have a 2010 F150 Lariat 4x4 with the 5.4. It has around 63,000 miles on it. I purchased this truck last winter and recently have noticed a pretty heavy vibration when the AC is running. It only vibrates when I am at a stop. If I apply a little throttle the vibration seems to go away or it goes away if I shift to neutral. The vibration is not violent but it is above average and I would definitely not consider it normal AC vibration.
View 14 RepliesI have a 09 s crew with 6 1/2' bed also. Lariat, Max tow package (most of the cool toys) I bought it certified pre-owned in April of 2011.
My vibration is between 35 and 45 mph. Not felt in the steering wheel but all the seats feel it. Set the cruise at 40 mph and it will drive you nuts.Dealer has had it a couple days for this and all they have found was a sticky rear u-joint.
I am at 35,500 miles so I am thinking about just dropping it off and saying keep it till you find the problem.
Just got a 2010 lariat supercrew...I put 1900 miles on it so far. When slowly letting off the accelerator (doing between 20-30 mph and between 1000-1500 rpm) there is a distinct rubbing sound for about 1-2 seconds...it is now sounding more like grinding now...took it to the shop today...(they couldn't duplicate (because service rep documented 60 mph instead of the 20-30 mph...went back at the end of the day to ride with the tech, and i was able to duplicate so now they have something to work with....also the noise happens mostly when the path of travel is either level road or slight to great incline..it has not happened on a down slope....
View 14 RepliesI've owned this 2012 Lariat 5.0 for about 6 months (has 49,500 miles on it, approx 6000 are mine).
For awhile, I had kinda thought I sensed a slight vibration/grinding when making right-hand turns. But it seems to be getting more noticeable now. It does not happen with every RH turn, but its not all that rare of an occurrence either. (Does NOT happen with LH turns.)
In addition ............ possibly related, sometimes while breaking, I get a somewhat similar grinding sensation, just before coming to a stop. Again, it does not happen every time.
I tend to think both of these could be a brake issue, but wondered if anything in the driveline could be contributing ? (I should note that I'm in 2-High)
2013 Platinum. See sig for details. 37,000 miles. 1 owner. Truck has been basically parked since June. However I take it out for a quick spin every 3 week for 10 miles or so. Currently has storage insurance on it.
When backing out of the garage the brakes are grinding and squealing bad. Also getting feedback through the steering wheel for the first couple miles which leads me to believe it's one or both the front brakes.
I have a 2013 XLT Scab that has been in twice now for a low speed to stop brake rubbing or grinding noise. The first visit they turned the front rotors and scuffed the pads, which seemed t fix the problem for about a month. The second visit they repeated the same process on the rear and the problem was good for about two months. Today while driving I noticed the noise, probably worse than I have ever heard. It seems like after about 20 stops the noise gets quieter. I am taking it back for the third time and I am hoping they will fix the problem for real this time. I am tired of burning my gas to get to the dealer and then having to ask my salesman for a loaner car. Other than this issue I love the truck.
View 6 RepliesWife's 2010 F150 4x4 85000 KMs makes grinding / ratcheting noise in LH front axle when in 2 wheel drive. Mostly when turning left some times when traveling straight never when turning right. Never makes the noise when in four wheel drive. I am suspecting the auto hub is the issue but wonder if others have had this trouble ?
View 5 RepliesFirst off I have a 2009 F150 4wd 4.6L truck...we have noticed a grinding noise on the front driver side wheel...we have replaced the auto locking hub acuator and the hub assembly but the noise is still there....it has us puzzled now not sure what it could be. I have read many different threads on this issue an it seems that it might be something to do with the vacuum. The noise is only on the driver side and only in 2wd, when its in 4wd it doesn't make the noise at all. Also while in 2wd the noise seems to go away when we let off the gas.
View 5 RepliesJust installed new actuator and wheel hub assembly on my 2009 f150,truck still had grinding noise in front passenger wheel , New solenoid and vacuum hose kit installed when test drove noise still there until you put the truck in 4 wheel drive it disappears . The noise returns as soon as you take it out of 4 wheel drive. Also mechanic said steering was tight,installed new shaft same thing, could this be the rack and pinion.
