Filter? Where is there a filter?

Did not know that the filter was aftermarket. Could this be the cause of the restriction making the steering hard?

Yes + no. If filter is clogged up it would quit assisting PS but that's after it caught debris it shouldn't have ever had to begin with so you have to fix that first or never get over this. You'll just keep blowing things up till it's all right.


Pump, lines, rack and pinion all at risk and may all have been harmed?

Possibly.............. You still haven't shown us what you are talking about.

Can you upload a picture too a hosting site like Photobucket and they will supply a link to make it show up here.

What kind of power steering fluid are you using in it? Hopefully the filter isn't on the pressure side of the system...LOL

I am using Prestone p/s fluid. I have replaced pump and bypassed the filter and the cooler, running the return line directly back to the pump. Still steers harder than it should.

Some of those had variable effort steering that was controlled by the body control module (GEM). There is an electrical actuator on the steering rack that is pulsed width modulated to control pressure at the rack to manipulate the amount of assist. The GEM uses the VSS (vehicle speed sensor) information as an input to determine the amount of assist. When the vehicle isn't moving the GEM should allow full steering assist and at highway speed hardly any assist. Unplugging the actuator should cause a default to full assist at all speeds.

I don't understand how the filter is being blow off, unless you have an abnormal amount of pressure on the return side before the filter. The filter should never be on the high pressure side or between the pump and rack. You may need to connect a power steering pressure gauge up to see if you have a rack or pump problem.

I'll check the GEM if it has one. Next thought is the possibility of a steering component binding up and causing the system to fight it with excess pressure. Off to the shop! Thanks for all of your help and I'll let you know.
