A little pro-active maintenance info, from my experience.
Noticed some play in the swing of the backhoe on my T9. Thought it was wear, but then I that the mounting plates for the backhow were moving. There are four large bolts, two on each side that secure the mouning plates for the backhoe to the body. All four of these bolts were slightly loose, just enough for the plates to move. There were no lock washers on these bolts, just some paint. I removed the paint, unscrewed the bolts one at a time, added lock washers and some Locktite before torquing them down.
You might want to check yours.
