I have an 86 F700 Hi Ranger Bucket Truck. My Upperboom groans when operating. I grease everything regularly. I've greased and poured gear oil on any visible cables, but can't pinpoint where the noise is coming from. Has anyone had this issue?

A few years back I backed in to parking spot to close to tree line and squirrels nested in back knuckle and chewed through 3/8 line between turn table and bucket. I was able to splice with quick connect, double female ends. Not expensive. May have to bleed line at turntable after. Happened twice. Mechanic charged $400 for about 2 ft. Next time did it myself. About $30 in material. Just located leak with peak holes. May have to splice in two spots if in-between peak holes. Leave enough slack but not to much where it's sloppy. I nosed into parking spot after that and shot as many squirrels till they stayed away. Lol.
