Ford Transmission :: 1997 - Driveline Noise And Vibration
Dec 27, 2013
It'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?

1988 F-150 4X4, 302, 5 speed manual Mazda transmission. I picked this truck up from a teenager and have been going through it fixing the odds and ends, just when I thought I was done a new one popped up.
There is an odd "clunk" in the driveline, but I cannot pinpoint where it is coming from. It happens almost exclusively in third gear, shifting up or down into this gear. It has happened in first gear one time that I can remember. When it happens, I hear the pop (clunk), then feel a slight jerk like when a chain slips on a bicycle.
I spent some time under the truck yesterday trying to locate it, but had no luck. Did find the yoke on the rear end , 8.8, a little loose. Found that the U-joints at each end of the driveshaft were worn out. The transfer case, BW 1356, was quite low on fluid. And there was nothing out of the ordinary with the transmission.
Tightened the yoke, replaced the U-joints, drained the T-case and refilled with fresh ATF and pulled the fill plug on the tranny to ensure it had ATF instead of gear oil in it. It did.
I hoped all of that had solved my mystery noise, but I wasn't that lucky so now I need to isolate it. Seems that if there was a problem in the T-case or rear diff, the noise would be present trough all gears wouldn't it? With it being primarily in one gear, could the problem be in the transmission? If so, can it be rebuilt for a reasonable price?

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.

On 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.

I 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.

My car definitely has a driveline vibration, but the steering wheel also vibrates. All vibrations are, however, intermittent as to when they come and go, and the intensity - on both the chassis and the steering wheel - can also vary.
Tires and wheels have been ruled out with 99.9% confidence at this point... What puzzles me is how a driveline issue in a rear-wheel-drive vehicle can affect the steering wheel (even though it can certainly explain the shaking of the whole car). In the end, it's all connected to the same body, but still... I am even wondering if my car has this driveline vibration PLUS something else (e.g., control arms in the front suspension appear to be a popular replacement part in these cars according to other threads).
Here is a link to the TSIB that I borrowed from another thread: [URL] ....

Read the owners manual and didn't recall this bit of info on crawl mode...It sounds as if your transmission/driveline is about to ruin itself. Sounds exactly as if the fan is hitting the shroud periodically. After years of ownership and 35k miles I decided to try the crawl mode....for about 20 secs. After a quick call to my service manager he assured me "that's the way it sounds."

When I'm in 4 high and I coast I can hear something from the front drive line. It's a soft whirring/grinding type noise.
If I'm accelerating there is no sound . Only when the driveline forces reverse and the engine starts to slow the truck do I hear something.
With my hubs locked but in 2wd I don't hear anything.
Is this something to be concerned about or is it regular noise?
We have had a brutal winter so I've been in 4x4 75% of the time.

I took my truck in for a clunking noise in the driveline as I come to a stop and sometimes when shift into park. It is now the 7th and I'm told parts have been ordered and the truck will be worked on when parts come in. I asked to speak to general manager and still no call back. I called customer relations and nothing they can do.
Honestly I think the have me on the back burner since I'm warranty work opposed to marked up repairs. Am I being unreasonable on my expectations of repair time? I called around and a ring and pinion job is quoted at 3 days at the most. Other repairs have been approved as well and parts are in for those, but they have not actually repaired them either.

2001 F250 7.3L 280k miles. Truck is new to me in the last 6 weeks. Was driving out to Glenwood Springs last night and I got a weird rear end vibration between 79 and 81 mph - couldn't say if it's a new vibration as haven't had the truck long enough. It's sort of still there over 81 but less obvious than bang on 80. Whilst the vibration was there I caught a slight dip in the road that caused a grinding noise to accompany the vibration - I'm guessing because something's was getting extra loading on the upside of the dip.
I'm away from home until Monday so my options are a bit limited, however while crawling around in the dark last night pushing and shoving stuff to see if anything was loose I noticed a couple of things:
Minor leak from pinion seal - but it has flung some spots of oil. Drive shaft 'center bearing'(? U shaped attachment on drive shaft to chassis with rubber bearing?) has play I can push the drive shaft at least a 1/4" with my hand and it seems a little sloppy but I'm no mechanic.
I'm going to check transmission fluid level today and top up if required and check the magnets, such that I can limp home as necessary avoiding 80 and get the diff checked and pinion seal replaced. Does the drive shaft bearing need changing or should it have that much play? I'm assuming it's LSD on the rear?

Have 2008 Santa fe with a driveline hum noise. Originally thought is was a wheel bearing so I replaced what I thought was the suspect ones (1 in front and 1 in the back). Noise still there! Carrier bearing on the drive shaft? Front axle shaft? I'm at a lose.

I have a 2001 Ford F150 with 165800 miles. I just had my power steering pump, PVC valve, and serpentine belt replaced by tire kingdom this Sunday 3/2/14.
After they replaced those parts, and I picked up the truck. I noticed the truck was making some new noises, these noises occur when I brake an it sounds like a small vibration on my dashboard and there is a noise underneath the truck. the sound also get louder when I roll up and down the window and run the ac. This had never happened before the repairs.
I took it back on Thursday 3/6/14 back to the mechanic and told them about the new problems. Now they said I had a brake problem. So they replaced the calipers, brake pads and rotors. But I still have the weird noise.
The truck still needs two rear tires a new high-end ac line and a freeze plug. Would any of these cause the noise underneath the truck or the noise in the dashboard or is there something else?

I have been hearing a slight "bang" from the front of my car , mostly when I either step on the gas or let off. It's very faint, but annoying.
So last Monday I make an appointment for the car to be looked at, and after the dealership telling me I need two other things (recalls/TS done before they will even look at the problem I am calling about, I ask that a tech be available to ride with me to cut down on the diagnosing time. They tell me that all this work will take over 3 hours, and because I live 11 miles from the dealership, they won't give me a ride, I can either get a ride from someone, wait, or get dropped off at a local mall.
After dropping the car off they tell me, other than the banging, I need a ECM update and muffler clamps for the rattling heat shield. I tell them the heat shield was removed because it was falling off and I was on a long distance trip and couldn't stand the banging against the car. They tell me, don't worry, we'll fix it. I ask that a tech ride with me and was told that, if it's audible, we'll find the problem. So, my first mistake was that I trusted them, and I leave.
About 5 hours later I get a call telling me the car is all set. I ask about the banging, they tell me it couldn't be replicated by the tech after a 10 mile drive. I was a little upset. So I guess the whole point to this story, if having any kind of noise from the front end, or when shifting into park or reverse, it's probably the TSB for the driveline axle washers.....

2007 Passat 2.0T, 48,000 miles
Essentially, I get a clunky/pop/crinkle sound from beneath my feet in the driver's side footwell. This sound/feel occurs when I either get back on the gas after slowing down but before the car fully stops or if I take my foot suddenly off the accelerator without touching the brake.
VW told me after three tries that the "noise is from the driveline changing directions, making some noise because loads are changing on the driveline when going from deceleration to acceleration" and that it was normal.
I have seen some posts about the subframe bolts either being faulty or worn on this site and other VW sites...

I have been recently working on a 2003 1.8T fwd Passat that I have owned since new. I recently changed the front rotors, pads and CV axles. At low speed everything is great. No vibrations or unusual harshness. Starting at about 35 mph a low frequency driveline noise starts from the driver side and starts to get drummed out by engine noise above 60 mph. The noise is not very noticeable from the passengers seat. Initially I suspected a tire, but I swapped tires front to back and the noise didn't change. I have tried loading and unloading the front tires in 45-50 mph s-turns and the noise doesn't change.( I was thinking wheel bearings). I put the car back up on stands and tried hand spinning the wheels. No unusual noise was present. I have not found any clearance issues where there might be something rubbing. I got the axles from Raxles and am at a loss. Could this be a wheel bearing or a bad CV joint? How can I tell?

I thought that my front wheel bearing was bad but I removed it and it seems fine. The issue that I'm having is a continous vibration (noise) in the left front that gets worse with speed.The half shaft makes a noise at the point where the half shaft meets the steering knuckle and when I turn the shaft at the outer splines, the grinding noise is present. My question is, is the entire half shaft supposed to turn, even the outer diameter of it that would enter the steering knuckle, or is the shaft supposed to turn inside of that outer diameter? I hope I was able to explain my problem clearly/
