This one scares me:
That frame rail, right where the spring shackle attaches, is a common rust spot, and not an easy one to fix.
There are guys here who seem to really enjoy fixing stuff like this. You might be one of them. Search for "Plop" and read his thread about fixing the rust bucket series of Wranglers he owns. He does nice work, and is a great craftsman. But I'm not 100% certain he ever actually gets to drive his Jeeps.
Me? I don't even change my own oil. I'd rather pay more money up front, and get less headaches and expense later. But I admit it's nice to finally be able to have that as an option!!
