Default How To: Power Steering Delete

Here's how I made my PS delete. I scored a MS steering rack to depower for a sweet deal. The Mazdaspeed rack has a faster turning ratio than the regular power rack.
Thanks to Tom at The Parts Group.

Here is a pic of the rack after removing the hard lines.

I first removed the tensioner assembly.

I then removed the end cap to remove the rack from the housing. There is a dent from a punch used in to lock it in place. I didn't know about it but it did not mess up the threads when I disassembled it. you may have to grind it before removing the end cap.

The next step was to remove the input shaft housing from the rack housing.

To remove it from the input shaft, you have to tap it out from the top and it pops out. The seal collar is not needed after depowering the rack.

I used a grinder to cut it then hammered it to split it and separate it from the rod. I also removed the clip. Seal and clip shown in second pic.
