More details would help a lot but going on the details you provided. I would guess possibly a defective strut or strut mount. A defective spring or one of its components. A defective shock and or possibly a bad ball joint. I would try pushing up and down on each corner of the car and see if you hear the sound then try to pin point where the sound is coming from and go from there. If you still don't know see a pro. , EzForJesus
This may be too simple of an answer so i apologise if it is too simple but your 96 Intrepid is equipped with anti-lock brakes. When your brakes lock up by pressing the pedale reall hard the car automatically will pump them at a super fast pace helping to slow the car better. Your car also might come with "Traction Control" Basically what this does is if the wheels are spinning it again will use the anti lock feature to try to regain traction so you may feel the same thumping on ice or real wet roads.
Check the lug nuts immediately. Check tha clip that holds the brake pad on. I had a loose pad that made more of a tick sound that went away when I pressed on the brakes
I would check brakes,shocks,and powersteering pump. I would check brakes,shocks,and powersteering pump.
brakes may need bled but more than likely vacuum booster is bad
get the person out pf your trunk...lol
Take it to the garage and have them check for a cracked rotor or a loose caliper.
Is it accompanied by a shuddering or vibration? You could likely have bad brake rotors.
you might have a vacuum leak in your intake manifold
Maybe broken motor or transmission mount
Could be universal joint is finished. A bad flex disk
I would advise bringing your car to a mechanic as quickly as possible. Your brakes could fail. This puts you at a high risk for injury or even death.
i don't know if this helps but i just had my car repaired tonight and when i picked it up this was a new problem that wasn't there before. i took it back and they said the thumping was caused by a rotor??? that they forgot to tighten? i am not sure i have the name right!
Could be the brakes are metal to metal.
The caliper may be hanging and causing the humming sound. I cant type the sound out but it mine made a humming noise as the wheels turned. If I pressed the brakes hard and quickly let go it would stop. I just replaced rotors and brake pads and it is back to normal now.
On average a loudspeaker reaches 3 decibels. Therefore a Bose speaker system would be about 125db. In that way the sound would lead to constant heart thumping.
start by checking wheel bearings. not enough info for a good diag.
sound like you have "grabbing" brakes to me. i would check them for contamination and if they are then you will need new brakes and to replace all rubber components, and if your brakes are not contaminted i would start checking wheel bearings, warped rotor or drum, and the balance of your tires. i would check your rotor or drum first, that is most likely the cause
It's probably a loose suspension or brake component and the axle assembly is shifting slightly when you hit the brakes. I'd have to hear it to be sure.
IT HAS BEEN MY EXPERIENCE WITH OLDER VEHICLES THAT WHEN THE CLUTCH PEDAL "CREEKS" THERE ARE SOME WEAR POINTS WHICH ARE NOT GETTING LUBRICATED
Most common cause would be a loose brake caliper mounting bolts.
You would adjust the brakes on a vehicle with abs brakes the same way you would adjust the brakes on a vehicle without abs brakes.
The bulb could be 'blown'. Remove the working bulb from the other light and try it in the socket of the one that isn't working.
You created a flat spot on the rear tires. Your car had a busted mount or bushing
I have the same issue with my 2003 F-250. Through some research I have come to the conclusion that the ball joints need to be replaced.
