No you don't have to remove it to install them, but it makes it much easier. My engine was out and I was installing new inner tie rods since I rebuilt the entire front suspension a few years ago, but you can install them without removing the rack. You'll probably want to remove the intake manifold to give you more access to the 2 on the driver's side. The pass side is just a bracket you remove and then install the new bushing (large bushing).Thanks Steve, also did you have to removed the whole steering rack? they have two sizes do you remember which size you used? my pupra drives a little shaky and i can feel the steering wheel shake a high speeds, i hope this makes it stiffer, along with the suspension bushings i'm getting done.
