Power steering pump?
On my 97 K1500 5.7L 350 V8 when im driving and turning to the right if it hasnt been driving most of the day it will feel like nothing is behind the steering wheel then it catches up and almost launches me off the road. most of the time i know when its goona happen so it hasnt been a huge problem. but i live in the higher mountains of idaho and in a snow storm yesterday it did it in a canyon i drive alot and i barley kept my truck from meeting the creek at the bottom. so now i am sure it has to be fixed if i wanna keep the truck around. the power steering fluid looks good and Im not losing any is it just my pump getting old and not working right or what? it does not do this if the truck has been running for more then an hour
Thanks for your help and ideas Nick

My first reaction was that you either have contaminated fluid or air in your power steering system. First, I would jack your front und up, start the engine, slowly turn the steering wheel all the way left. If it jurks and grabs you have air in the line. You can purge the line by loosening the power steering cap and turning the wheel slowly as far as it will go until you hit resistance then go the other way. Keep the fluid full and the air will work its way out . If this doesn't sound like the issue, remove the fluid from the power steering pump and fill with new DOT 3. I would try these before replacing the pump. Good luck.

Quick question does it do it on slight turn (35mph curve)then steering turns super easy?If thats what its doing it needs a evo sensor(electronic variable orifice sensor) this steering system will give you full assist in parking lot manuevers and less assist at higher speeds,when cruising and sensor glitches steering goes to full assist giving a oversteer condition.

So its back again I am goign to try the evo sensor since its still to the right and there is no leaks. What i need to know is would this part also be called a steeringwheel speed sensor(auto zones web site.) Or i also saw somewhere else that you can only get this part at the dealer unfortunatley the closest dealer is 100 miles away and 50 of it is in a canyon that is dangerous enough without your steering being dumb if anyone can help me find this part it would help out alot.

Before you replace sensor, look under dash above sensor and if its never been replaced there will be a rubberband holdin connector and unplug sensor,this will cause steering to stay in full assist then drive and see if problem coming back if it does then i would replace steering gear because pump does not know what direction you are turning.hope this helps with diag
