Do NOT put spherical bearings in both ends!!! The shorter upper control arm travels through a different arc than the longer lower control arm. This is why the factory lower control arms had the oval bushings. The soft rubber will allow the fore/aft deflection in the lower arms and not cause any more bind than 100% necessary.

Once you go to polyurethane in one end of the lower and then a rod end in the other end, the lower basically is a rigid link. That is why the PM3L uses the stock rubber bushing on the frame end. This is the "last link" that will allow for that different arc travel.
