| Check all the boom fold points/bushings. Replacing pins and bushings is fairly common. Just make sure it hasn't worn into any castings. The inner most pins (on the rack) are the worst to do, but not as common. Check all the rivets on the breakaway. Common failure point, but you can put bolts in to repair and the breakaways are reasonably priced if you have to replace. If you look at one that isn't all cleaned up, a bunch of grease on the inside of the wheels is a good thing. It means the struts got greased regularly. Gear oil on the inside of the wheel is a bad thing. Hub seals can fail.
I will also echo what someone else said and get the 4045 if possible.
