I drive a 02 grand prix with 88k on it about a month ago I noticed what seemed to be a vibration in the pedals and the steering column. At this point there was no signs of a problem because I wasn't driving on the highway, but the first time I took it out on the highway I noticed that when I reached 70 mph that a slight shuttering was occuring. Now the problem seems to be worsening, when I drive between 70-72 mph the shuttering increases and can be noticed in the dash. At 75 mph the vibration is at its max but sometimes when I push through the speed to 80 mph the vibration seems to reduce. Thinking it might be the roads I have driven on four major highways and all the same result, however on rare occasion the vibration doesn't occur at all so the mystery continues for me. What is a good starting point? Before I forget, lft front rotor was replaced 3 months ago and brakes felt great up until this month, where it seems like even breaking it just seems as if there is reduced effectiveness as the wheels turn and slow down but grab fine at other points in rotation.
I also had this problem and found that the cv joints in the transaxles were bad. I replaced the axles at a cost of $65 dollars apiece plus the cost of labor.
Try checking your bearings on both sides. as for your brakes when you change your rotors try changing both of them as well as your pads. i had the same problems and that fixed it. if it persists i would look at your ball joints and then your calipers. good luck.

Typical behavior for a wheel is out of balance. Get all four checked. Also look for bulges on the inside of the tyres. If the camber is that noticeable, you also need wheel alignment doing as well. It also sounds as though the suspension or steering joints are severely worn, and if a top or bottom joint fails, the wheel falls out, top or bottom leaving you stranded on the road.

ConditionSome
customers may comment on a moan, groan, shudder and/or vibration noise
while making low speed turning maneuvers. Customers usually notice this
condition in parking lot turning maneuvers.
Correction
Diagnose the power steering concern. Refer to Symptoms - Power Steering System (SI Document ID #670351).
Replace the steering gear with a newly designed steering
gear. See the parts information below. Refer to Power Steering Gear
Replacement (SI Document ID #742314).
Hi, this symptom is usually caused by warped brake rotors. You can have your rotors resurfaced at any brake shop or you can just buy new ones, depending on the cost breakpoint for your vehicle.
when you hit curb it dammaged wheel bearing very common its the equvant ot hitting with a sledge hammer also check ball joint tie rod inner and outter wont cause noise but can be dammaged aswell also have car sent to alignment shop in case some parts were dammaged or bent
plz leave me a comment reply if you need any more info
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.
