Re: Replacing rack and pinion

Now the hardpart. Are there wires running into the rack in the area where the steering coupler attaches? If yes magnasteer. If no standard power assist. Ebay has some pictures of racks if you seach there you might get a view of what i mean.

Does the pressure line connect directly to the power steering pump or does it have a valve body between the pump and the line. Direct is standard. Valve body is magnasteer.

Then again maybe the local dealership will run your VIN and give you the definative answer.

I belive I read the hard right steer problem was a defective pinion bearing in the rack and was a dealer fix (not a total recall) for many GM racks. Might try to shame them into a fix. Might want to search around for that.

Hope this helps.
OK, that's the info I needed! I am almost positive that it must be standard power assist. It's an SE, and I definitely don't remember seeing wiring connected to it or a valve body in between the pump and rack. I will jack it up and look one more time to be absolutely sure though before ordering/working on it. I appreciate all the help everyone, thanks.
