Vibration at 2000rpm

Acceleration to engine around 2000 rpm, a vibration noise from car underbody. Somebody said the exhaust bracket (downpipe triangle bracket cracks) to cause noise. But I removed that bracket already, but the vibration noise still there??

    Hi, thank you for all your hints. Today, I check all the bolts,the heat shields and tap the exhaust pipe to see any loosen. I found the noise come from the down pipe. And at last I found a bolt missing. i put back the missing bolt and tighthen it . The noise is reduce much. I think the rest of the rattle noise is come from the heatshields. As the car is already 130,000km.

Have a good look then you may see the problem also the front pulley as their is often a ribber bonded strip in the middle and these break loose causing you sort of vibration .Another source of noise is if the car ceramics inside it have broke up and rattle .

My car makes a droning or humming sound around 2000 rpm along with vibration but it goes away as soon as I increase the speed or come to a stop.


could be the timing belt tensioner. with the timing casing removed place a socket extension bar on some metal then to your ear as it will help you locate the noise. be careful tho. failing that big end shells i would check. hope this helps

During highway driving, my 2005 Ford Excursion Diesel seems to vibrate intermittently @ 2000 RPMs and speeds between 62 - 75 MPH. I can accelerate through the vibration or keep RPMs below 2000 to...


I would first check the u-joints on the driveshaft if the problem only happens when the speed is between 62-75mph. Then check all the tires for lumps or bulgesin the sidewall or tread surface. The tires may also be out of balance and bouncing at that speed. If the vibration occurs only when the engine is around 2000rpm, check the pulleys, serpentine belt and anything driven by it for looseness. Also, check the trans mount to see if it is loose or broken. If everything checks out ok, have the OBD codes checked to see if anything might be causing the engine to surge.

ther are no lubriction points on the driveshaft,if you rev the engine does the noise get louder or go away?try power braking the car ,make sure e-brake works properly if so apply it ,place the car in drive,place your left foot on the brake ,right on the accelerator,rev to 2000rpm for no more than 10 sec, this is like puttting a load on the drive train,this may unmask your noise,it appears this may be some sort of exhaust rattle since nothing is moving undereath car
