With the arms installed, the Panhard-bar axle and chassis mounts are next. With the new arms in place, but before installing the springs, position the axle mount around the lower-control-arm mount. Install the supplied 1/2x11/4-inch bolt in place of the original shock mounting-bracket stud with a supplied washer and Nylock nut on the backside. Don't put a washer under the bolt head because interference with the shock will occur. Rotate the axle mount around the 1/2-inch bolt to equalize the vertical alignment of the control-arm bolt holes on the inboard and outboard sides of the axle mount. Torque the 1/2-inch bolt to 120 lb-ft. Next, check the vertical alignment between the control-arm bolt holes of the axle mount and the axle's lower-control-arm mount. If the holes are vertically misaligned by less than 1/8 inch, they're OK. If they're off by more than that, then the shock-mount area on the axlehousing is bent. It can be straightened by removing the Panhard-bar axle mount and bending the area back with a large pair of locking pliers or a pipe wrench. Use wood to protect the metal of the shock-mount area. Our car didn't require this procedure.
