I always buy arms with bushings. I'd recommend the same when you get back from your trip, etc.

I will be reusing the arms. Ounce they are installed as long as they are working OK I will leave them there. No sense to pull them if they are working.
I bought a complete front suspension kit thinking that I would have worn ball joints and ect. But they are all tight. I think I will leave the old one on there also.
I will pull the upper control arms off today; but if they are good I will also re-use them.
I am begining to think the the prior owner had some suspension parts replaced but did not change the Control Arm Bushings; maybe because they were afraid to mess with the adjustment on the bolt.
