Just did LCA swap this weekend with a friend of mine. Was surprisingly very easy install, especially after reading about other people's experiences on the board. The comment by rOx is spot on, no DIY is needed...just the right tools...and his list is perfect. Bought new CA and Powerflex bushings from Bimmerworld during their sale. Cars drives over expansion joints in the road like never before...no more darting.
Some other points:
-I just reused the old carrier (lollypop) bolts and used some loctite
-Had to go out and by new wrenches due to the 21 and 22 mm wrenches needed
-Was able to snake a socket (using several extenders and a u-joint) from the opening near the oil dip stick handle down to the nut on the drivers side balljoint and take it off with an air gun.
-Pickle fork (plus a few had wacks from a mallet) popped the ball joints out easily
Would highly recommend getting the bushings prepressed into the lollypop. Also highly recommend the Powerflex bushings.
