When I am driving along a curvy road whether it be a slight curve or major curve, which ever direction I have the steering wheel, it will suddenly pull/jerk to that side as if someone is grabbing and pulling it. So if I am curving to the left, the steering will jerk to the right. Any ideas what may cause this? Last year I had something fixed with the car where the steering wheel would shake violently when driving at about 45 mph and up (can't remember what the repair was), and now I'm having this problem. Also don't know if this has something to do with it, but after they repaired it, I was hearing a sound, took a look and there was a rope dragging, attached to the bottom of my tahoe. I can't remember what those ropes are called, the have a hook on each end.

I had the fuel pump changed. It has had trouble starting ever since. It does start and runs great, it's just hesitant to start. Do you think it's something the mechanic did wrong, or is it something else?

Sounds like the toe-in alignment is way off.

Okay thank you. I need to correct my description. When curving to the right it jerks to the right, when curving to the left it jerks to the left. Thanks for your answer.

For the Tahoe's starting problem, I would change the platinum spark plugs (ACDelco only), if they have not been replaced in 50,000 miles.

Before having the alignment checked, I would jack up the front of the vehicle and check the steering for looseness. My gut is that the ball joints and/or tie-rod ends are shot--this can be serious.

Okay thanks! I can't wait to get rid of this vehicle! Have to wait about another year until we get our other car paid off!
