First off make sure your rear driveshaft zerk fittings arewell greased. There are 3 of them. This might alleviate some of the noise.
However, the best fix is not cheap...adjustable rear links. With these you can adjust the angle ofthe rear axle/diff to correct the angle. Two places have them available for the VX....Independent 4x and Stinky Fab. Another optionis to have a local 4x4 fabrication shop build you a set.
