I am doing the same part at the moment on my mk2 vr you can do it without dropping the subframe
but its a bit tricky I undid the bolt holding the uj onto the rack and a bolt inside the car and used a flat screw driver
to lever it up on the rack
just make sure you line the hole up spot on with the spline
if the engines out i would drop the frame slightly my engines in could not be bothered taking it back out
