-Not very difficult at all. To replace those two, your looking between 15-45 minutes.
-Mine just went out as well. Went to the local autozone and they said $35 a pop
totaling $70 for just two! I went on Amazon.com and ordered the two hood arms, and the two rear hatch arms for $70 shipped to the door. They were about $15-20 each.
-It's basically just screw out, replace, screw in.
