Don't have to remove it for just the cover and chain. I pulled the front cover on the CJ5 twice in one week (don't ask!!
) without removing the grille. I had to unbolt the fenders and support rods and let the grille swing forword to remove the cam though. To remove the front cover, it sure would have been easier without it there I'm sure.
Remove the headlights to unplug the wiring and then remove the harness from in front of the grille. Unbolt the fenders at the front, three bolts on each side. Loosen the support rods and slip them out of the 'U' brackets. Remove the center body support bolt under the fornt and lift it out. Probably missed something that someone else will catch...
