This^^^ and Not only does it get knocked out, but it galls the chassis mounting slots during the process, and cams makes live adjustments possible (weight on arms) so you don't put the bushings in a bind when you tighten the bolts.

How much do you off road? Without them I knocked my arms around almost every time I went out, but I drive kinda crazy. With them its MUCH less movement and all I really need is a slight toe adjustment. The amount of adjustment is there with or without them, they just make the adjustment easier/proper and better locked in place. At this point if the truck drives good and tire wear seems reasonable just save on doing the cams till your next alignment.
