There is a bar that goes from one side to the other side in the front of my 1996 chevy s-10 and it connects to the tires. well each side has come off of the place where they connect to the tire. what is this part called and what do i need to reconnect it?

well there are several poles at the rear tire. one is the strut it has a spring wrapped around it. then there is a trailing arm that runs from the front of the tire and attaches to the frame. then there is a stabilizer link rod that attaches to the strut housing and the rear sway bar.

More info.? Front tires or rear? Front tires are bolted onto a hub which connects thru the spindle into a constant velocity joint(CV joint) and goes into the tr-an-smission on a front wheel drive like you have.
Rear tires are mounted to an axle,which can be independent suspension or an axle which reaches from the left tire to the right tire.

If the bar goes from side to side it is called a sway bar. If it goes from one side to alittle past center it is called the stabilizer bar.

on my 96 Cavalier, it's at the front, on the passenger side, and you can see it if you get under the car. Kind of in front of the tire (very near the front bumper).

check the sway bar links. the sway bar is the long solid bar that goes to each tire up front. the links are what connects the bar to the lower control arm. this is what controls the vehicle from swaying or drifting

yes it can it's over 10 years old.

WI replace the wheel bearing and put brakepads on.This is when the problem start...When I am driving I hear a stumping and humming sound. 1996 CHEVELETE BLAZER . YOU CAN PUT IT IN FOUR WHEEL DRIVE

I have the same issue (which comes and goes often).
It is caused by a loose wire connection, used for the drivers side airbag located in the seat.. The connector for mine is located under the front drivers seat. There are a couple of connectors that are connected to a bar under the front of the seat. I don't recall which one is used for the Airbag sensor.
