Steering Rack ratio change

rob · 09-30-2004, 04:35 PM

This may be a dumb question because I don't know the internals of steering rack too well. I have a '95 WRX rack that has a slightly quicker ratio than my '00 RS. Is it possible to simply swap out the drive gear from the WRX to my RS rack in order to have a quicker ratio?

While I haven't done this, I have heard that the steering racks pretty much explode when you take them apart. However, I have heard that you can swap the internals and convert your RHD WRX rack to a LHD WRX rack.

I have a spare steering rack out of a Legacy turbo that I'm going to take apart tommorrow. There is a valve assembly that the pinion gear is part of. I don't know we'll see if explodes or not. The pinion gear is pressed into the valve assembly, so you need a press to take out the old one and put the new one in. I would guess the gear inside the rack is matched to the pinion so you'd need to swap that to.

I looked at the diagrams in the FSM. It looks to me that the control valve assembly is probably different from LHD to RHD because of the line routing. Maybe not. But like you said, the pinion can be pressed out. Now I had the same question you mentioned; are the pinion and geared tie rods matched sets? And if so, are the tie-rods LHD/RHD specific? Hmmm...
