I pull my drives and store them inside every winter. At the same time I inspect hoses, bellows, cables etc. The u-joints are supposed to be greased once a year also. If you have to replace hoses or bellows you will want to buy the special tools to make life much easier and their not much money. Mine is an 89 with over 600 hrs and the engines and drives look and perform like new. If it aint broke it's going to. Don't go by me though because my motto is if it aint broke dick with it until it is.
