It's time again (every other year) to disassemble, clean, inspect, and reapply Slip Plate.
After cleaning all moving parts get 4 new layers of Slip Plate.
This hitch will be 10 years old next month. Other than paint scratches shows no sign of wear.
I paid a little more 10 years ago for the Superglide automatic slider. The quality is now paying off. I see no reason this hitch won't last another 10 years and beyond.
