Just finished the install and it was slightly challenging. My car has 91K so the bolts were REALLY on there. Used some WD-40 and air tools and finally came off.
During my install I DID NOT drop the steering the rack, I saw no need at the beginning. There is one bolt that the boot is in the way but it does come out. If anyone else has insight on the steering rack drop please chime in. I am not mechanic and always looking to learn.
One thing I did notice is that the original leveling rod snapped onto the old lower control arm. The new one you need a bolt on both ends and the car only had 1 bolt so I had to run out and get one. Just a tip!
I did the M3 controls arms and Meyle HD outer tie rods. Next step is the alignment.
Thanks for this great DIY!
