SOURCE: front end vibration

It sounds as though your car has two seperate problems. The first problem with the vibration that goes away when you let off the gas pedal is caused by a bad INNER CV joint. It only vibrates when you are accelerating because that is when the joint is under stress. Your vehicle has two axles, each with an inner and an outer joint. My suggestion is to have a competent shop determine which is the bad side and replace the entire axle. The second vibration which occurs at any speed is most likely cause by either a bad tire, or a bent rim.

SOURCE: I have front end vibration

just checked this out a while ago:



Wheel Hub Assemblies: Systems and Diagnosis of Worn Hub Assemblies & Bearings
Front wheel hub assemblies and bearings control the position of, and reduce the resistance of, vehicle wheels in contact with the pavement. When they fail, front wheels may not be kept in position and vibration and noise usually develop. Symptoms that normally develop as a result of these worn parts include:

  • A humming, rumbling or growling noise which increases with acceleration or as the vehicles turns
  • Vibration felt in the steering wheel, which changes with vehicle speed or as the vehicle turns
  • Looseness or excessive play in the steering wheel (especially while driving over rough road surfaces)
  • A loud, constant grinding noise when driving the vehicle (heard in the most severe cases of a wheel bearing failure)
  • Pulling to one side when braking.
  • Roughness - with the vehicle of the ground, roughness or vibration when rotating the wheel
  • Looseness - with the vehicle off the ground, looseness when wiggling the wheel back and forth (Looseness may also indicate a worn ball joint)
  • Excessive brake pedal play can also indicate sloppy or excessively loose wheel bearings
  • ABS failure in the system may be related to failure of the ABS sensor in the hub assembly or the internal sensor in the wheel bearing

SOURCE: loud vibration on 2005 jeep liberty when under load.

Sounds a lot like a wheel balance problem, Does vibration go away over 55? In checking driveshaft joints...If you looked at them with the vehicle in park with the wheels on the ground, the shaft is "loaded" and cannot be correctly checked. To do this properly, vehicle should be in neutral with both rear wheels off the ground. Sometimes a joint can appear to be tight but still be bad. Check for traces of powdered rust around the rubber boots right where the end caps meet the cross on the inside. Any rust there indicates lack of grease and the likelyhood that the joint is frozen.
Check both balance and joints. Good luck.

SOURCE: Vibration and noise from front end while driving

Jack up the front end and put stands under it and block rear wheels. Look at axle boots and see if they are cracked. Try turning wheel back and forth sharply and see if you can hear any clicking. Problem could be outer axle joints. If the boots are cracked or you hear a clicking noise you will have to replace the axle. The axle and boot come as a complete unit. Please let me know what you find out.

SOURCE: subaru vibration

I had similar problem with my '99 outback. Replaced the front half shafts and seemed much better. A few months later seemed to be comming back so replaced the driver side shaft again and the problem disappeared. I had put in rebuilt shafts and the driver side shaft was not rebuilt correctly.

I have a 2007 Pontiac Torrent FWD with a violent low speed vibration. we have replaced the lower control arm assembly and the hub bearings along with the brake pads and rotors.


Struts would not cause vibration problems, A CV joint could, turn your vehicle in a parking lot hard right, make a circle than turn left make a circle ,if you hear a noises you have a cv joint problem. If you feel vibration on the steering wheel its in the front, if you feel it in the seat its in the rear.
Tires out of round & Balance very common as well brake rotors cause vibrations.

I replaced my tierod on the passenger front.there is still some play in the left to right there is also a humming sound at speeds 40+mph. it's coming from the hub bearing or ball joint.


Any wear or play in a bush or rod usually gives a 'knock' or causes vibration, not a humming noise.
If there's play in the steering wheel that may be due to a worn steering rack and pinion.

A worn ball joint can cause a 'crack' noise and depending on the wear, vibration that will be felt through the steering wheel. A worn ball joint can also cause the car to pull to one side.

A humming noise suggests it is either a brake rotor/pad, or a worn driveshaft or wheel bearing.

Front end vibrates and steering wheel vibrates at over 70 mph


there are so many differnet things that could cause this it impossible to say without a test drive or jack up car and doing some test
some possible causes are :

Bad tires
bad bearings
bad tie rods
bad rack and pinion
Out of alignment
bad control arms
bad ball joints
bent or struts
warped brake rotors
etc.

After 55 mls. speed my car start shaking, I changed the rack and pinion but the problem still, do I have to alignment it after that change? thanks


you certainly do need to do an alignment after changing a rack, but that will not help a vibration issue. vibrations can be caused from a bent or out of round wheel, out of round tire, out of balance tire, shifted belt in a tire, unbalanced brake rotors, or worn bushings. good luck!

Steering wheel starts to vibrate at 55 mph vibration goes away at 65 mph or if i maintain 55 to 65 mph while applying pressure to the brake pedal vibration stops. also when drive over a curb, (e.g.backing...


i would suspect somewhere in your front end you have a compliance bushing with excessive movement. these cars front ends depend heavily on these style bushings, and as they wear you can start to see tire wear patterns, looseness in steering, and high speed vibration. make sure you have the front end inspected by a shop that is familier with these types of cars. good luck!

Brake pad and rotor problems creating an on-going noise and vibration. Pads in front and back have been replaced;also rotors have been ground.


you need to replace the rotors.On new vehicles the manufacturer designed the rotors along with other parts to be replaced at certain mileage or ware.When they ground the rotors they became thinner.So now when the brakes warm up the rotors are easier to warp,which is the problem your having now.

1996 dodge grand caravan vibration 45 mph to 55 mph replaced right front axel still same problem vibration no felt in steering


Vibrations while driving like you are describing can come from tires that have defects (internally broken belts) (wheel weights that have fallen off) or a bent rim (perhaps from another driver [not you :-) ] hitting a curb) Are the tires worn? Have they been balanced and rotated regularly? You report no vibration in the steering wheel.
Vibrations during braking can be warped rotors or discs (but this doesn't sound like your problem since these kind are usually felt in the steering wheel during braking).
If and only if you feel like you can do this safely,
you can try getting the car up to 55, placing the car in neutral, then switching the "engine off" but leave the "key on" (be warned the power steering will go out but the vehicle can still be steered though the steering wheel will be much stiffer) if you try this (do it perhaps in a vacant parking lot or on an empty road) and the vibration goes away with the engine off but while the vehicle is still moving, then the vibration is engine or transmission related. If this is the case you might hope for maybe a bad engine mount. Bad engine mounts can be diagnosed with the vehicle stopped as well. However, if the vibration remains with the van moving forward but with the engine off, the vibration is likely a problem with the tires or suspension. Try to provide some more info.
If you don't feel comfortable trying the above suggestion, please take the vehicle in to an ASE certified suspension and steering professional for further diagnosis.

Finally, I had a similar situation happen to me today. I was riding with a friend in their van and the vehicle started vibrating more and more around 55 mph. We stopped and carefully checked the front tires (including the lug nuts for tightness) but
found a tire defect. (it had several broken steel belts that caused a bulge in the tire and thus the vibration) We changed the tire and the vibration was gone. Good luck to you.
