OK, , no I have not had my tray out, so I went and tipped back the bed so I could access the "D" bolts. I used a dial, inch pound, 1/4" drive torque wrench (96 inch pounds is 8 ft lbs. I then sprayed penetrating oil and let sit for an hour. The bolts popped loose from their torque lock at 96 inch pounds. Removed, inspected, cleaned the surface rust, completely coated the threaded sections with anti-seize and reinstalled/torqued to 96 inch lbs.lou1947 said:The bolt is Metric 8x1.25 320mm length which is about 12 inches. I will try the baking soda tip.Will keep you posted on the repair. Have you taken your batteries out and checked the trays and bolts? .
The bolts had minor surface rust which I cleaned off with penetrating oil. Other than that, not the tray looked fine and the bolts looked fine.
