The Driver!
It doess that because the fuel pump is being shifted and the gas is being pressured causing a sudden jerk.
most likely bad balljoints
how
I have a 97 suburban and the steering randomly slips causing the truck to jerk the direction it slips because the driver will over correct the movement. The steering will slip to the right majority of the time.
Your shoulder's Jerks.
You could have ignition problems if it is the engine causing the jerk.
I've got a better question, why is this question in the Chevy venture forum ?
Most likely needs the front rotors turned or replaced.
It jerks because the gas tank is on the left side. When the tank isn't tightly screwed on it may hit the inside parts of the car causing it to jerk.
4x4 will jerk when accel. especially while turning. It is alot of torque on all four wheels pulling at the same time. You should only accel slowly with 4x4 on, especially in 4x4 low.
The AC compressor puts quite a load on the engine, especially one with less cylinders. It puts a load on the engine, causing it to jerk back and forth.
My hands jerk and it is getting worse, it began a week or so ago. When the jerking began I noticed that I had double vision. Any ideas of what is causing this? Thanks. Bren
