replaced rack and pinion and the steering wheel jumps back and forth when you try to turn it. It turns by itself one way when you touch it and bounces back and forth

Hi,

When you replaced the  rack and pinion, did you mark the proper orientation of the pinion shaft and made sure that it is positioned properly e.g. 12 o clock?  Were the rack secured properly or bolted properly on the cross member? Another scenario that can cause this problem is a worn out pinion gear .

It was bolted good and properly and i mared it before i installed it, but it seems to have air in it and i can't get it out to stop steering wheel from jumping back and forth. Can't turn the wheel at all on my own it does it automatic when you try to turn it. I am a good mechanic just never experienced this with rack and pinion before. Is there another solution i have replaced it with another new rack and pinion and it still does it? thanks Speedy

Hi,

Normally, you can bleed the power steering if so equipped by letting it run in park position. You can observed the bubbles in the power steering fluid reservoir.  In your case however, it is different. Can you make sure that the power steering pump output (high pressure) is connected to the inlet valve on the pinion gear housing. Most power steering the high pressure inlet connector is the bottom one ( this is the one coming from the power steering pump), and the top inlet is the fluid return back to the power steering reservoir.

Please check the hose orientation and make sure the hoses coming from the pump are connected properly. Otherwise, the rotary valve gaskets or O rings are bad, which I doubt it though.
