Thumping at front passenger wheel area

When I go down the road in my car, there is a noticeable "thumping" sort of vibration coming from the front passenger wheel area(the faster I go, the faster the sound gets), at first I thought it was because that tire had a bulge in it, but after replacing that tire, it was still there.

At around 35+ MPH, that is when it starts to be audible, and noticeable. When I drive at 35+ MPH around a curve to the right, the noise goes away, even while I maintain speed, or accelerate. If a shock were to "break", or whatever it does when it goes bad, does that make that particular wheel bounce all over the place, creating that horrible noise? I suspect a broken shock, and a backyard mechanic suspected that also, but he did not know about the noise that goes on.. help! I don't want my tire to fall off while I go down the road!!!!

    The steering wheel does shimmy, a bit. Its always shimmied, but not at
    such a low speed, usually it was at 65-75 MPH. As for the brake pedal
    pulsing, no, it doesn't pulse. I had the front brakes completely
    overhauled a 1.5-2 months ago. Calipers, Rotors, Pads, Hardware, etc...
    (600+ dollars later!!!! Car isn't worth that!!!)



    Hopefully the shimmying of the steering wheel will help you narrow it down. heheh

    I have the same problem but with a 2004 Mercury Grand Marquis. The
    thumping sound is coming from the drivers side wheel area and ceases to
    make noise when I turn left or apply the brakes. Turning right however
    makes a louder noise. Steering wheel shakes at speeds above 35 mph and brake pedal does the same. I bled the brakes about a week ago and didn't
    bleed the ABS pump or HCU. Book says that not doing this could cause
    your pedal to become spongy overtime, but did not state that any other
    damage could occur.

If the noise isassociated with "wheel speed" then it is in the rolling parts... axle hub bearing brake rotor caliper wheel or tires...if it goes away on right turns then you are unloading or separating the issue then...so a hub /wheel bearing /axle issue is most likely...does your brake pedal pulse when you feel it..(riding the brake while driving)..does the steering wheel shimmy ?

Rear thumping


John,
i have the exact same problem in my 2010 Veracruz. Had it to the dealer 5 times. They say they can't "duplicate" the sound. They say they check the suspension and all is ok. I leave the dealership and the next day I hear the thumping. I also notice that on a snow covered road, the car is very hard to hang on to. Seems like when you go down the road, the rear end wants to kick out to the right. Personally, I think there is something wrong with the drivetrain. Possible an issue with the AWD trying to kick in the right rear wheel. Wheel Speed Sensor?? Who knows?? I'm really frustrated. The dealer is useless.

What is the cause of continual thumping (appears to be coming from back of car) and violently shaking?


Many times, rear tires that are out of round or severely cupped or feathered, or that are out of balance can create this type of issue. My first recommendation would be to have them and the wheels on the rear of the car inspected. There may not seem like there is much wrong visibly if you look at just the tread of the tires, but a good tire tech can spin them up and give you some solutions, and the inspection itself is inexpensive. Hope this helps.

Thumping coming from front end all speeds.


IF IT ONLY THUMPS WHEN YOUR CAR IS MOVING YOU COULD BE WRITE. PAY ATTENTION TO THE THUMPING CLOSLEY, DO YOU FEEL A VIBRATION IN THE STEERING WHEEL, IF SO THE PROBLEM IS IN THE FRONT END. IF YOU FEEL A VIBRATION IN THE DRIVERS SEAT THE PROBLEM IS IH THE REAR END. YES THE VIBRATION FROM THE FRONT STEERING AND THE DRIVERS SEAT IS A WAY TO TELL WHERE THE PROBLEM IS
