Bearings for the pre-1990 Cobra's are unsealed taper bearings. For the 13", 4-lug wheel, replacement bearings are available at auto parts stores like Autozone.

Large, inner bearing: Timken "Set 8" L45449 - L45410

Seal for this bearing: Timken 224015

Small, outer bearing: Timken "Set 1" LM11710 - LM11449

Wheel drums are available from Eastern Sailplanes for $125.

After recent misadventures with a disintegrating bearing en route to Florida I have added bearings and grease to the spares/tools in the trailer.

Hi
I have a 2002 cobra trailer. The owner manual says I have permanently seal bearing. Now I have no idea what this mean. I am totally incompetent in mechanical things. Does it mean I have nothing do maintain.
