My LCAs have stayed quiet lately, so I haven't replaced them yet. I did order the heat shields and screws, though.
Yesterday I decided to upgrade the front end links, since they can pop/clunk when the ball ends wear out. I bought the Steeda adjustable units, set them at stock length, and installed (which required three wrenches to keep everything aligned). Clunks galore! Got under the car today and the ball ends had developed play (everything else was tight)--Steeda must have gotten some bad parts. Put the stockers back on (which were actually in perfect shape) and will contact Steeda in the morning.
Sometimes in this hobby you have a zero sum game day...LOL.
