When I replaced my front sway bar bushing...I only loosened the subframe bolts, and pryed it down say 1 1/2 to 2". Now, according to TH, you can grind down a 13mm wrench (I think that's the size) to 1/2 the original thickness and remove those bolts w/out dropping the subframe. I just couldn't see it. Took me like 3 hours, cause you can only turn those bastard bolts like 1/12 a turn every time. But others have had better luck.
