Once you get both axles installed and tighten correctly try using two straight edges off of the axle flanges and measure out from the axles flanges straight forward and then on the back side also, I use 16 inches form center each way, to see if the axle housing is bent If it is bent it will be either wider on the front or rear and than the other way, same thing up and down also Let us know what you find, my Duster rear end was narrowed and the axles would not slide in easy after the narrowing. It ended up bending the pasenger side axle housing (after several years fo racing the car)bad enough to rip the ladder bar mounts off of the housing
