Re: Front subframe

Only other option I can think of is to cut or grind off the bolt heads then deal with is after the K member is removed.
But that will be a challenge as well. The nuts are "floating inserts" inside the frame.
Perhaps another route is to drill a small hole to allow you to spray penetrating oil on the nuts and end of the bolts. Have you tried a good impact wrench with a large 3/8 or 1/2" air hose? that might work as well. past that no bright ideas...
