The oil pan on my 2003 Rubicon is just about rusted through. I ordered the parts, oiled up the bolts for a few days, and started in on it. Much to my surprise, almost all of the bolts came loose without a fuss. I needed to wrench on one bolt with a pair of vice grips. The bolts I'm struggling with are at the very front of the pan, and they're blocked by a piece of suspension equipment that was installed by the previous owner. I don't know what it is to Google its removal.
I tried to unbolt and take the piece down, but it would not budge. So here I am, asking for some help from some seasoned professionals.
Here are some pictures. Any advice on what it is and how to remove/lower it would be highly appreciated.
