Working on rebuilding the center arm in my '78 FJ40. Have disassembled the old, greased, and reassembled the new internals and tightened as instructed. It feels as if the grooved part that connects to the bottom of the center arm(Pitman Arm?) and that connects to the tie rod ends doesn't move as freely as before. Will the center arm be more difficult to turn as a result of replacing the internals? I greased the heck out of everything inside so I don't think that is an issue. I tightened the top cover until tight, and then backed off a 1/4 turn before tightening the top bolt as instructed by the Body & Chassis manual. However, it appears that the top cover doesn't screw in quite as far as the old one. The top of the old one seemed to be flush with the housing. Any ideas? Thanks in advance.
