Review on 🔒 Auto Locking 4WD Hub Link - Ford/Lincoln Compatible - Replaces 1C3Z-3B396-CB - Fits 1999-2004 F250, F350, F450, F550, Expedition, Navigator - Front Left/Right - 1C3Z3B396CB Replacement by Eric Hanson

This part is relatively easy to install yourself. When installing the part I encountered some resistance from the included o-ring. After several attempts to install the ring, I finally found that it's a bit thicker than the old one and I can't use it. I had no problem installing the new part with the old o-ring. The retaining ring MUST be installed correctly or the part will accidentally snap off.
