[quote=javajeep;198999]I have a completely different solution that worked for my 1997. It is simple, but counter-intuitive until you really think about it.
1. Jack and support on the frame. You have already done this.
2. Put your jack on the front differential and RAISE the axle just a little -- about 3 or 4 inches.
Here is why it works. When your axle droops, it droops in an arc -- not straight down. In other words, when the axle droops, it also moves toward the rear of the jeep. When you raise the axle a few inches, you also move it FORWARD. The key is not for the axle to droop more, but to move it forward more.
Hmm that sounds interesting I have to give it a try next time I do an oil pan on my son in laws 89...Tj
