I want to replace my rack and pinion on my car I was told by GM dealer that if I bought a used one it could not be reprogrammed to make the steering work. Is there anybody who can help me?
Do you
have the same problem?

They are not wrong. Basically if you put components from another vehicle into this one then they will not be able to change the calibration to match your vehicle and this will cause issues in the performance of the power steering.

The way this works is when you install a new component (gear/rack, control module or entire assembly) it is a "blank" unit with no programming. Then you install it and program the VIN into it and then train all the sensors to match how that vehicle operates. Once this is done, you cannot program it to another vehicle so if you put the parts on, the control module will continue to operate the system as if the other parts were still on it. Unfortunately just because the parts are the same part number they will operate slightly different and this is what the module is being trained too. It is learning the characteristics and quirks of those specific components and then once they are programmed to one vehicle it cannot be "relearned" to another.

I attached some info for this. Let me know if you have other questions.

Thanks for this information. Now I understand how it works. So I will have to buy a new rack from GM and have them install and program it. Thanks, chevyguy55.

Good afternoon

I do not know your ability for repairs but this is tight to get to and remove.

I attached the procedure below for you to view.

What is the issue that makes you think you need the rack?

My garage mechanic told me there is a crack in the steering rack. And the steering wheel makes a noise when turning the wheel.

Thanks for the update. Yeah, unfortunately that leaves only one repair for that issue.

Let us know if you need more info or how you make out when you wrap it up. Thanks
