Just did mine last night. Very difficult to get the bolts off my '02, but sprayed them down with Liquid Wrench and then was able to get a 15mm socket on the bolts and get them removed. It is a tight spot, but something that worked for me was to slip the socket on the bolt, and then attach the ratchet and extensions to the socket. Sounds convoluted, and it is, but it worked. Appears to be the most difficult part of the job, but I need to complete the RMS replacement, so time will tell. Good luck!
