ok so basically you take the ps rack and completely disassemble it
then you take the center section out and cut the main seal out its a metal ring and you have to be careful not to cut into the center section
then remove the rest of the seals (wich slide right off)
then you take the pinion gear housing and take all the hydraulic components off till you are left with just the pinion gear and the big bearing
since the pinion gear has a mm or two of twist (to assist in the direction change) you weld it at that point and so you dont get any slop in the steering
next you grease the pinion gear and the rack gear teeth and re assemble the rack
once its reassembled the trick is to back off the tensioning nut about 3/4 of a turn so that the steering effort gets lighter, dont go too far with this as you will not have enough tension to keep the pinion on the rack and you will end up with sloppy steering
so just play with it to dial it in to your liking
it works great for me i even added a set of 5mm spacers i made on the tie rods for more steering angle
