lower control arm bolts

[ahamtw]

i am installing lower control arms on my 1999 e320 w210 mercedes.
ever thing was going good until i tried to remove the front bolt, when i get it almost out it hits something near the bottom raidator hose, it still likes about 1 inch before the arm will drop out . i have searched the internet forums to no avail. no one seems to have had this problem before, if anyone can help,i would appreciate it. tks
