Cruiser RV axles.. Could my axle be one of the problem ones?

You can have it professionally aligned at a heavy duty truck/trailer suspension shop for little more than the cost of freight and labor to install a new one which may or may not be straight when it comes from Lippert. In addition they will check and adjust all 3 alignment factors. Tracking, toe and camber on both axles. If you think your axle was out out of spec when installed why waste $$$ on another one that could be the same?
