I have a 2001 Bullitt. I get this vibration/grown when taking off in first normally. cant seem to figure it out. New struts, springs, rotors, brakes, wheel hubs. the sound last a second. only at certain rpm. almost like the car has to hit a certain vibration from accelerating before it happens. only hear it on acceleration.

are there any points I could grease or lubricate ?

thanks

Could be bad motor mounts, or unbalanced driveshaft. Is it automatic or standard?

Bad motor mounts would have the motor shaking around a lot more than normal but if they were bad I would imagine you would notice it when driving at any speed. The driveshaft you can go to a shop and have them balance it for you. A unbalanced driveshaft would cause noticeable vibration but I could be wrong.

What are the chances of it being an un balanced shat? what would cause the shaft to go out of balance?

thanks everyone. Its actually not a vibration issue that i feel, its more like something vibrating causing a sound.

Could it be a bad lower ball joint? the boots are torn. I purchased the car used. No telling how long its been torn. can ball joints make noises other than "clunking sounds" ?

Most of the time you can check mounts by a visual inspection, have also put a piece of wood under the pan and gently tried to raise the engine/trans. and watching the mounts(usually separation of the rubber from the steel).

Ball joints can make a metallic squeaky sound but its more a turning thing than an acceleration or rpm thing.

Maybe not the whole drive shaft but the u joints could also be shot.

FOUND IT! its in the rear passenger brake. When I go supper slow it sounds like its a warped rotor. gets loud than goes away gets loud then goes away. if I pull the emergency brake a little it shuts up. the rotors are brand new. any advice?

thanks

I would look it over and if nothing obvious I would trade it with the other side's rotor and see what happens.

should I had a grease to back of pads? its a vibration hummm sound.

General karthief · Oct 21, 2017

Do not grease the back of the pads, you can try spray'n the back of the pad with blue brake anti squeel stuff but most pads now have a anti squeek pad built in, swapping the rotors is a good idea too, see if the sound follows the rotor.

ace305 · Oct 21, 2017

Awesome thanks. the pads do have the anit squeel pad on it. I will swap them around and see if that helps. thanks everyone for the advice
