For instance, on one Oldsmobile the book says you have to support the engine and lower the sub-frame by, at least, three inches. Well maybe you do and maybe you don't. I have always been able to twist and turn and jiggle it out through the wheel well opening without too much difficulty.

But absolutely read the procedure first. It will give you torque specifications, what, if any, nuts and bolts need to be replaced and if there are any "O" rings that you need to replace.

Before taking anything apart. Look at the new rack. Take note of mounting bolt holes and the high pressure and return line fittings. Then jack up the car and support it with jack stands NEVER go under a vehicle support only by a jack.

Take a look at where the mounting bolts are, where the steering column coupling is and the power steering lines. After looking at what the job entails, you may decide it is beyond your skills and have a shop do the job.
