Removing & installing new frame

If you are talking about the front subframe assembly there is indeed a bunch of spot welds. I replaced the whole front section,- frame rails, inner fenders, and radiator support,- as a one piece assembly on a wrecked Jeep Liberty. It has a very similar layout as our old Mopars except the front and read subframes are connected. It was actually easy to line up. I had the body blocked level. When I slid the new assembly in place everything lined up perfectly. I didn't have to do any extra work to make it level or square but you certainly need to measure to be sure it is. To me the most frustrating part was drilling all those spot welds, first to take the damaged part off, then to prepare the donor part. Once that was done and the new part slid into place and tacked, the rest of the welding seemed like gravy. Just make sure your welds penetrate well and a few extra here and there certainly won't hurt.
