+# Sliding Door Assembly - Tracking Improvement
+
+## Overview
+
+This modification addresses tracking issues within the sliding door frame assembly that can cause poor door movement and alignment.
+
+## Solution
+
+The tracking performance is significantly improved by adding a small 6mm OD, 3mm ID bearing (MR63-2Z) to extend the screw assembly. This modification ensures that the screw head and bearing track properly within the T-slots on the frame, resulting in smoother door operation.
