Since my front is jacked up, I'd like to jack up the rear to hopefully locate and 'fix' a fairly loud bang when going over fairly hard bumps. Getting the front was a problem enough since I have two aluminum jacks. One three ton the other about one ton (barely makes it). Even with the front up pretty high I can't locate any area in the rear which could be safely used as a jacking point.

Of course I need to leave the side jacking points free to get my jacks under.

If it requires another three ton jack so be it.
