Replacing front stabilizer link on W140
 

I have to replace the front stabilzer link on my 1992 300SD. I see only two nuts I need to remove it. Does anybody know how hard it is to get at the top nut? Do I need to remove the wheel and brake calipers? How hard a job is this? ANy tips would be appreciated. The dealer wants $275.00 to replace one side. I can buy the parts for $50.00.(Both sides)
Thanks
