Got a problem with the power steering on our 97 Tahoe. There is a hard spot right off center. You notice it when you are in a long radius turn like on a highway at speed. It kind of comes and goes. It will cause the vehicle to jerk to one side (not severely) until you get past that hard spot. You do not really notice it as much when going straight down the road. The problem went away for a while when I added some Lucas power steering treatment, but it's back again. Anyone got any ideas, or quick fixes?

Thanks

It's the electronic steering sensor. I've put 3 on my 97 p/u with 200k miles. The part is cheap, like $20. My buddy who works at the dealer put it on in a few minutes, says there's nothing to it.

Are you refering to the steering wheel position sensor, or are do you mean the electronic variable orifice at the pump? According to the GM manual the steering wheel position sensor plus the vehicle speed sensor feed into the power steering control module. The power steering control module then outputs a variable voltage signal to the electronic variable orifice valve at the pump.

Thanks for the tip, I didn't even suspect that it could be a sensor problem

Just priced a steering wheel sensor, $60.85 Think I will do some checking and confirming before I just arbitrarily replace it.
