Bmw :: 1997 - Thumping Noise Coming From Drive Line
Jun 28, 2014
A friend brought a '97 Z3 roadster by the other day for my opinion.Cute little car with a nearly new top and tires, and supposedly a recent clutch. Peppy 2.8L DOHC I-6. Just over 100K miles.
The only thing I could really fault the car on was a thumping noise coming from somewhere in the drive line. It is only noticeable on starting from a dead stop. It doesn't seem to matter whether you start out slow and easy, or like a jack rabbit, which it does well. You hear THUMP THUMP THUMP, and can almost feel it under you as you drive. The differential is VERY near both passenger's backsides. If you start out hard it may be more like THUMP THUMP.... THUMP thump THUMP before it quits making noise Of course the car has independent rear suspension. I'm thinking it may be a rear CV joint in need of lubrication. This car did sit for nearly a year recently as it was tied up in an estate. I don't know if that's part of it or not, but it might be.

t's a '00 extended cab swb 4.6L with 4r70w trans. I have a Hotchkis TVS 2/4 kit on it. It's been lowered 3 years now and I've never had any real issue. But I started noticing a small vibration through the floor so I took my driveshaft out to be balanced and new U joints installed. Ever since then I've had an audible "hum" from the rear whenever I go over 75mph. It only does this under load (hill, etc) and I don't hear anything until then. The driveline shop told me it was my pinion angle and I've tried shims with only slight improvement. I'll replace the driveshaft after I do a motor and trans swap down the line, but it's out of the budget for now.

I have a 98 F250LD, its a Lariat, so everything electric/auto. Shift on the Fly 4x4, 5.4, 188K, Factory rear air suspension. Typical Minnesota rust. Anyway, I just noticed in the last 75 miles or so, a drive-line vibration. There is nothing until 39 MPH. Then from 39-41 MPH there is a decent vibration. Stops until 50, then from 50 MPH up it is a steady vibration. I have already changed the u-joints in the rear shaft. I have pulled/wiggled on everything else I can think of with no luck of finding of anything loose.
One thing I did notice, is that the front axle is locked in all the time. How long it has been like this: years for all I know... I can flip the switch from 2wd to 4H and 4L. It all seems to work fine, I hear clicking, the 4x4 engages, the proper lights come on/off. The front axle will pull when supposed to. The transfer case seems to be working fine, but the front axle won't disengage. I am hoping this can be fixed cheaply/easily (DIYer), and also hoping this explains my low fuel mileage.
Front axle? Where to look or what to try and fix for the vibration?

I have a 1997 F150 that has been making an odd noise (something new and different). It seems to be coming from the engine-ish area. It makes a hollow whooshing kind of noise, followed by a thump/thud that I can feel through the accelerator (think frighting off beat base drum living under the hood). It sounds like a very large valve of some kind closing. It does not do this all the time, and both times it has done it have been at low altitudes- might not mean anything but my truck doesn't seem to like low altitudes- it idles low there. It has done this twice now- once 2 or 3 times in a minute for about 50 miles and then it just stopped miracle!.
I added oil in the interim of that and I thought maybe that had worked- it was embarrassingly low- took 4 quarts to get it to read half way up the dipstick. I might have murdered my truck. It did it again when I was on a long trip, coming home. It only did it 4 or 5 times. My truck kindly listened to my desperate plea and hasn't made a peep since, which means I made it home but now I can't get my mechanic to have a clue. I tried that the first time and he said "hmm." That was incredibly useful. So do I need a new truck? I might be able to afford a 1998 model.

I tried searching, but couldn't find anything. I have a '97 F-150 with the 5.4L and I have a plastic line coming off of my intake that I don't know where it is supposed to go. I don't know how or when it got disconnected, but I can't seem to find anything within reach of it that it can connect to.

What would be the cause of a thumping noise coming from the right rear (pasenger side)side of the SUV. As I speed up is gets louder and faster. Check the tire it looks ok. Didn't check the other side of it.

I replaced my struts and shocks a few weeks ago and i installed lowering springs H&R. Yesterday i started hearing this knocking thumping noise coming from the right front of the car me and my uncle took the wheel off today and looked around and everything was nice and tight we proceed to both push down on the right corner of the car to have it bounce up and down and we heard the same knocking sound coming from the right front area it sounds almost as if the strut blew out in the front right would the symptoms i described concur with the front strut being blown out, and on a side note the struts are only a few weeks old is this even possible since the struts are so new? I do have 20" rims on the car with low profile tires could i have hit a pothole hard enough to cause the strut to blow out? Iam planning on taking a trip to the dealer tomorrow and have them check it out.

I have a 1997 Voyager that I am having a thumping noise that is coming from a black module that is mounted in the engine compartment over the passenger side fenderwell. It has 2 vacuum lines and an electrical connection coming off of it, one of the vacuum lines has a tag on it that says EVAP. The engine seems to be running fine, although every now and then it seems like it might idle a bit rough, and there are no CEL on or codes in the computer. Don't know what is this module called.

I am original owner of a 2000 CRV, it's in really good shape and has been maintained by me on about 99% of all repairs it has 140k total. I have this thumping noise coming through the floorboard by my feet, under moderate acceleration and it goes away at just about any speed when you quit accelerating. Sounded like a bad halfshaft, I had already replaced one so I did the other side, got worse. So I replaced the one that had been in for just 2 years--no better. Asked the auto parts store for a recommendation and went to that shop, they balanced the tires, checked rotors and concluded I was buying junky rebuild half shafts. I had them replace the one they thought was bad with another rebuild, just as bad or worse...
I took home and put in both sides with new halfshafts, I also noticed some play in jackshaft bearing and replaced that as well....no better. Shop claims that a website they subscribe to says that 50% of aftermarket halfshafts for CRV are no good. But honestly we are 5 for 5 bad, last two were new from NAPA. Pulled things apart and checked wheel bearings left side was sticky so had machine shop press one into the knuckle, right side was done about 14 months ago. Also disconnected drive line and drove it as a 2 wheel drive vehicle....no better. Would a broken tire belt only make noise on acceleration or after a corner when you accelerate? Is this a possible indication of my transaxle going out? ---

My rearmost drive shaft u-joint is bad and has slop. I've been having vibration for about 7-8 months, but just started hearing a noise within the past week, especially when taking off with a load on the drive line (uphill or heavy acceleration). The vibration has not gotten worse, just that the noise has just begun to show itself.
I have one u-joint which is OE and has 275K miles on it, and it seems to be OK at the moment. The other two (including the rearmost unit) both have about 100K miles, as does the center support bearing.
Just because I don't want to worry about anything, I'm going to replace all three u-joints with Moog Super Strength units, and will also replace the Center Bearing with a new Spicer unit... just because I can and don't want to be pecked to death with multiple failures in the same drive line. I ordered the Moog joints because the only Spicer joints I could find were for the 4wd configuration.
That's the context... here's my question... The parts are on order and won't get here for several days. I've been driving the truck like it is at about 1500 miles monthly. Do I continue to drive the truck for another week before getting the joints and bearing installed? I know it's a guess... just looking for more perspective.

When driving I hear, not feel, a slight thumping noise that if I had to guess would say is coming from the passenger side front. When I let off the gas the noise becmes more prominent and you can feel the thumping. Also when I apply the brakes heavily the sound/feel goes back to the same as if I was driving. I'm thinking CV joint/axles or spindle bearings, but I cant understand why the condition is at it's worst when I'm coasting. Has this "noise while coasting" problem.

I was on the way to the airport in my 2004 Hyundai Accent last night when a loud thumping/clunking noise starting coming from the rear end. At first it sounded like a flat tire or something stuck in the tire so I stopped to inspect but everything looked good. I continued my trip as the noise continued to get louder but made it home. I worked on the car for several hours today and have not had any luck nailing down the cause. The sound appears to be coming from the drivers side rear tire area and would get much quieter when I turned right. It sounds like a spot on the wheel is hitting something but I don't see any area that shows signs of wear. Things I have checked:
- Jacked up back end and spun both tires, both spin with no noise and have no play.
- Removed both rear drums and inspected but all looks good.
- Inspected all rear end suspension bushings but don't see anything that stands out.
- I did notice the strut on the drivers side has some play where the passenger side is tight but when I rock the car up and down I hear nothing.

When driving in any direction, my left front wheel makes a thumping noise. it's not the tires, i have brand new ones. i can feel the thumping in my gas pedal, and if i were to let go of the steering wheel, the car moves to the left really hard. i have had people tell me wheel bearings, and i have had people tell me warped rotor.

Take a look at the video I recorded with my phone and you can hear a thumping or clunking noise coming from the rear driver side tire. The phone was held upside down sorry!. I'm thinking it's either the brake pads or wheel bearing?
Please try to ignore the wind noises. = Just want some idea so when I take it to a mechanic it would be easier to identify the problem. [URL] ....

Wondering what could cause a driveline vibration after a new clutch was put in at 136,000 by a repair shop.. The vibration was not there before, could the halfshafts or the motor mounts ,engine brackets if not installed exactly as before cause this, am bringing back to shop to get this corrected.

So my Ex squeaks at low speeds. If I turn the wheel slightly it seems to make it worse. The other day I had the rear end on the ice. Accelerated and spun the tired. I could hear a squeak squeak squeak. I lifted the rear of the truck and put it in drive. No squeak. Every thing sounds fine. I put it in N and spun the drive shaft. Maybe some noise at the transfer case? Could that bearing leaving the transfer case cause it? That an easy fix? Or ?? I also note some chatter occasionally from the rear end. I did just change the fluid. But may need to do it again. The squeak is the more annoying problem at the moment.

I have clicking noise coming from the accessory drive on my 3.3L 06 sonata. It started off as a squeaky noise upon start up. I have since replaced the belt and the tensioner and now it is a clicking/ticking noise. It seems to be a lot worse when the car is just started and it slowly goes away upon warming up. In addition, when the car is cold the voltage light will turn on around sharp turns and steering will get hard (almost like something is putting drag on the belt). What it could be?

so my r32 recently started making a nasty popping noise. the sound seems to either be coming from something in the rear end or drive shaft. not sure why it happened. i went on a 2 hour trip. got there parked it. aired it down (bags) but then when i came back and when to drive it again. it all of a sudden it started making a horrible popping noise. i thought it was the front wheel bearing going out since i knew it need to be replaced but i did that today and its still making the noise.
The noise sound just like a RWD car with a welded diff when it turns. kinda has that locked rear end hop popping noise. i lifted the whole car off the ground and put it in first to let the tires spin in the air but of course theres no weight on them so it doesn't make any noise. i'm really stumped on what it could be. im going to take the driveshaft off and see if it still dose it. then i know its for sure in the rear end. What it could be?

I have a strange vibration that radiates from, i think, the drive line or transmission.

This is probably always present but I hear it most at low speed if I am off the gas and brake. Slightly accelerating or lightly touching the brakes seems to reduce or stop the noise. It is a knocking noise coming from the right front and the rate is related to car speed. I am guessing CV joint. What is it?
