Power steering is jerking

SOURCE: steering

sound like your powersteering pump or steering rack and pinion
could be bad.i would say it is your rack and pinion because if your pump was bad your steering would be real hard to turn instead of being jerky.jerking is usally the sign of a bad rack

Hi,
Intermittent hard power steering, at the begining of the turn of the steering wheel, once disturbed past the hard part, works normal.
Had fluid change, I notice a sensor, on the control block tower of the rack, is this at fault ? thanks buckleyeng.

Check the U-joints and axle baerings. But its most likely because the truck is in four wheel drive.

A common problem with this model. Its the sterring speed sensor.A small disc shaped switch at the bottom of the steering shaft next to the floor. IT actually slips over the steering shaft, so, you'll have to disconnect shaft,pull column back towads you to replace. The reason for this switch is to stiffen steering at higher speed.Once it goes bad it starts sending mixed signals to the steering box. A simple fix? Unplug it at the switch like I did mine after I replaced it the second time.
