sudden front end shake
 

2005 Monte Carlo Ls
3.4L 6cyl.

yesterday out of the blue my left front end began to shake and pull to the left. I didn't hit any potholes or curbs. by the time I got home the shaking was so bad I expected to see my tire flat on the rim, but it was fine.
today I had my tire pulled and everything was inspected. The tie rods, bearings, rotors, brakes, steering arms, etc are all new.
there are no obvious signs of a broken belt in the tire. we put the tire on the back and the shaking is considerably less, but still there.
Any ideas what to check next or what may be causing this?

did you have the wheels off recently?
 

If you have taken the wheels off recently and you over torqued the lugs when putting them back on this will cause the brake rotor to warp and the incident you are describing is similar to that. Or if you drive down the Mountain and ride the brakes. :confused: They will heat up the rotors and warp them. Also if you throw a tire weight that will really make it go nuts,


Not long ago I was on about 50 miles of winding roads and doing the speed limit. I passed a parked car along the way fancy rust colored sports type (ricer) little chic driving it. Pretty soon she is right on my back side I could see the color of her eyes. So I am thinking lets see what cha got. The next curve said 45 miles per hour, I kicked it up to 65 into the curve, I am driving a 2014 Chevy Cruze RS, I love that thing, it only had 1K on it, before long I couldn't see that little sports (ricer) Oh and I never used the Brakes.
Hope you figure it out.

No, haven't had the wheels off recently. But this morning my husband was driving it to work and the tire on the front passenger side blew. Its the opposite side to where the shaking is felt.

If there was a reduction in vibration when you put the tire on the back the problem is in the wheel/tire. As you mentioned, a belt in the tire may have separated, or a weight may have come off the wheel throwing it out if balance.

New tires please
 

If you had on that just blew then its time to get 4 new ones go where you want but I have been able to purchase from Sam Club over the years they do a free balance and rotation around 5K or so and they have a full road hazard warranty make sure you get that where ever you go. :nono: It is to late to think about new tires for the car when you are in a Cart Wheel roll on the High way I have seen it. :thumbsup:
