Do not just pull the front drive line. The np203 needs it as it is a full time transfer case. It supposedly will try to send the power to the front, and will not move the vehicle well.

I had one, but I had both my axles working.

Also most shakes on a leaf spring truck are the tires. Not enough movement in the bushings to get terrible shakes supposedly.

Use balance beads in the tires since they will constantly change to suit dynamic needs. I use them exclusively now, and never have issues of tire balance.
