Vibration in front end

In my 2000 grand prix gt my car vibrates when i'm on the gas starting around 40 mph and when i'm going at slower speeds turning to the right. i don't know to much about cars but i'm thinking the problem would have to be in the front left of the car. can anyone give me some ideas?

    Car starts to rattle and "grind' when I reach speeds of 35-40 and stops as lay off the throttle. Seems to be in the front. Also, the engine noise is absurdly loud as I accelerate past 30.

SOURCE: Front end vibration at 40 mph and rubbing sound

Vibration at 40 mph hard to diagonisis without looking at front end. Could be wheels need balancing, new wheels and rims. Loose or worn suspension items.
Bring vehicle into a tire and alignment shop. Most Sears auto center have them.
With regards to rubbing noise again hard to diagonisis without looking at the affected tire, probably a splash shield hitting the tire in reverse.
Alignment shop will find the problem.

I had a nail in front passenger tire. Took it off and got it plugged. I noticed a lot of grease around area.


Could be universal joints if rear wheel drive , you can physically see by checking the drive shaft at each end. If its that bad it will fall. Also could be tires out of balance

Vibration from about 40-60 mph is usually attributed to wheel balancing, but the onset when you hit a bump seems to indicate play in the steering linkages (tie rods etc) or suspension members and stabiliser bar rubbers but you had that all checked out, that brings us back to the wheel balancing.

If this is happening at around 40 to 50 mph and it goes away when you go faster or slower then those speeds you probably need a wheel balanced. (please rate if this helps any Thank you)

Car vibrates above 40 MPH


your wheels more than likely needs to be balanced one or more are out of round if you had the tires rotated before the alignment this would make the vibrating more noticible.but balancing should solve your problem.

If your tires were not properly balanced then it will cause that. Also, if your rotors are warped then icould cause this to happen. YOu would also notice it when braking if rotors are warped.

Front end vibration


on both my Camrys, i had this problem. You could really notice it when you were driving down the road going 40-60 mph and punch the gas - car would vibrate, let off the gas - vibration stops, punch the gas - car vibrates...... On both, it was the CV joints. It is much easier to just replace the drive axles (with the new cv joints and boots already installed). For my last replacement, i think thy were only around $65 each.

Front end vibration


this is most often caused by worn out drive axle constant velocity joints or CV joints as we tech's call them, have them checked for torn boots or excessive wear, I am sure one or both will be found.
