This may not cure your problem but it's worth a try. Bleeding the air from your power steering system is accomplished by turning the steering wheel lock to lock in both directions with a dwell of about 2 seconds at the lock position. My "mysterious" problem was cured one day when I had to turn my truck and trailer 180° in a very restricted space. This amounted to lock to lock steering about (30) times. I had performed the procedure previously with no success cycling about (2) or (3) times. Ed |

| Lately while driving my 1998 GMC sierra 1/2 ton, I have noticed a grab in the steering while turning. It seems to do it when turning both left and right. It does it at almost any speed, and is starting to get annoying. It seems to jerk the wheel out of your hands, and steering seems over responsive. Does this have something to do with the speed sensitive steering. All tires have the same PSI, and power steering fluid is in check. Any clues as to why it does this. | |

Replying to: gregalpa (Nov 24, 2005 3:57 pm) Have you had any luck diagnosing your problem? Anyone else have any suggestions or can someone recommend an appropriate troubleshooting guide or manual that would cover the 4x4 system? Thanks |

If this ok, then would suspect TLA (Temperature Linear Actuator); threads into transfer case on passenger side. |

Replying to: mikec8 (Dec 03, 2005 3:20 pm) I had a 1997 Ext. Cab (GMC) 1500. I had the same problem you are having and they replaced something called an EVO sensor and it fixed the problem right away. The feeling it gives in the steering is very odd and it is almost like the steering skips. Ask about the EVO sensor/? and see if that can be done to your truck.

Just thought I would pass on the solution to a problem I was experiencing after some gasket work done on my engine. After trial and error of everthing from sensors to the computer and all parts in between. It was a faulty pickup in a brand new distributor. A defect from the factory that cost me 11 hours or mechanical trial and error. Goes to show you that even new they break down |
