Bmw :: 1997 - Thumping Noise Coming From Drive Line
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.
Caravan/Voyager :: 1997 - Thumping Noise From The Engine Compartment
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.

View 3 RepliesFord - F150 :: 1997 - ABS / Brake Light On And A Really Loud Noise Like A Bad Bearing
Well, got a 97 f150 4x4, and I have the abs/brake light on, and a really loud noise that sounds suspiciously like a bad bearing. So I go to my mechanic, who said it was the front passenger bearing going bad, and replaced it. Got the truck back, and its still noisy, abs light still on. The noise gets way quieter when I turn hard right. What the cause is? Or what I could check?
View 6 RepliesFord F-150 - 1997-2003 :: 2000 F150 - Grinding / Squeaking Noise When Backing Up?
I have a 2000 F150, 94k miles, manual transmission, 2WD
About 6 months ago a slight squeaking sound started when only backing up. Now its progressed to a sort of grinding metal on metal sound with regular driving as well as in reverse. I can hear it the most when its in gear and I take my foot off the gas. I changed the breaks, checked the wheel bearings, did a clutch test, and the u joints look fine. Something weird happened yesterday, while raining out, it didn't make a peep. My drive shaft and u joints have a layer of rust on them...could that be a cause of the noise, and it went away when wet?
Ford F-150 - 1997-2003 :: Grinding Then Thumping Going Into 4wd - Vacuum Solenoid?
I have 97 4x4 f-150 V6 4.2 litre that in 2wd tries to go into 4wd causing a grinding then a thump. When I put the truck into 4wd there is no grinding or thumping.
I believe one of the vacuum solenoids could be bad. Just was wondering which one would cause it to want to go into 4wd while in 2wd. The left most solenoid looking under the hood is the 4wd and the other with the pink vacuum is the 2wd.
I have no vacuum from the solenoids but from the lines going into them.
Ford - Mountaineer :: 1997 - Thumping Sound - Front Axle Diagram
Looking for a diagram that breaks down the front axle components of a 1997 mercury mountaineer? I believe my drivers side ball joint is shot because it makes a thumping sound whenever it goes down the road and the wheel has a lot of play in it.

Driving home from work (a 30 minute hwy cruise) I had to stop for a traffic light. As was sitting there I hear a thumping noise from under the hood, otherwise it was running the same as always. Got it home and I didn't hear it anymore, looked under the hood while idling, seen nothing, shut it off. top rad hose had a slight amount of pressure, started it and it quickly built pressure and felt a rhythmic thumping in hose and it got fricking hot quickly. I figure either a head gasket or cracked head.
I just recently did an aggressive cooling system flush using Prestone heavy duty cooling system flush (can only get this at a dealer) because the previous own neglected it, and it blew a head gasket, tons of rust inside when I did it. I'm gonna borrow a tester to check for exhaust gas in the cooling system and what did it end up being? The guy I bought it from (the previous owners mechanic) put 1 or 2 head gaskets on it.

View 3 RepliesFord - Explorer :: Thumping Noise From Front / Wheel Bearing?
I have a 03 explorer with approx 160k, I am experiencing a thumping noise while driving. It gets worse on right turns and gets better on left turns. initially i thought LF wheel bearing so i ordered a hub assy and replaced LF. noise is still there. I guess, thumping noise caused by wheel bearings, i know its usually a grinding kind of whirring noise.
The noise doesn't seem to change with accel/decel so I don't think it is driveline related (diff, drive shaft etc.) should i bite the bullet and replace the rf as well??? I should also mention that there is also a shake in the steering wheel that seems to coincide with the thumping (i.e., my hand shakes along with the thumping, and the shake gets worse when the noise does)...
Ford F-150 (2004-2008) :: 2005 - Thumping Noise In Front
My 2005 F150 is making a thumping noise in the front end. It increases as speed increases and is more pronounced when turning wheel left and almost goes away when turning to the right. Sometimes at higher speeds I can feel it in the gas pedal. Seems to be coming more from the driver side but I could be wrong On that.

1997 F150, V6, 4.2L. Replacing the O2 sensor, driver's side before the converter. I've tried using the O2 sensor socket (I have a full set) and it keeps slipping off. Afraid I'll "round" the sensor even more. I've tried heating it up, penetrating oil and it's not budging at all.

I have been told by the AC shop that my AC manifold is leaking. I have a f150 1997. When they say manifold do they mean both the suction and high pressure lines? In pictures it looks like the AC manifold includes all the lines to the compressor.

My 2011 F350 - 6.7 has developed this KRAZY thump, snap noise under the hood, loud enough to be heard inside the cab, and I cannot find out what the heck it is. It is not directly connected to the motor, you can rev it and the noise does not change. the thump is like, every few seconds or so, especially when the motor is cold. I am afraid this is a 2000 dollar noise and the truck is out of warranty.
View 8 RepliesFord Ranger / B-Series :: 1998 - Loud Thumping Noise From Dash
Ok I have a 1998 Ford Ranger XLT 4.0L automatic 4X4 with A/C my problem is i just had the timing chain,water pump, thermostat, upper and lower hoses, and front crank seal replaced. I got it back and right away noticed a thumping noise at idle only... My gauge was always steady at the same spot it had always been. but the thumping was loud when idling. Now the sound seems to have moved farther towards the engine instead of the dash and tonight when i popped the hood noticed the top hose was collapsed and i could feel no pressure. the thumping noise seems to be coming from the area of the thermostat. I have no oil in the coolant and no coolant in my oil! I tried to get the air bubble or pocket out if thats what is the problem by running the engine till hot with the radiator cap off but it made just a huge mess. it did seem to push a huge air pocket out but still does the loud thumping. This all started the day i got it back from the mechanic so I am assuming its an air pocket. I planned on changing the thermostat tomorrow.
View 14 RepliesFord Brakes/Suspension :: 2002 2WD Explorer - Thumping Noise When Accelerate
I have a 2002 explorer 2wd. I am trying to find an answer for this thumping noise as I accelerate. My first thought was a tire. I took them to be checked and had one replaced but all are good and less than 5k miles on them. I feel it in the pedals and in the steering wheel. The repetitive sound increasing with speed. I have, in the last 2 weeks, changed front rotors and pads with no difference in sound but good brakes now. And today replaced the drivers side upper ball joint and the front ds wheel hub assy. And no difference. What may be the problem?
