3/4 Ton of fun - ‘95 Sierra

When you have fixed it make sure to lube it well when sliding it back together. Aluminium likes to stick to itself. That damage looks like it has been getting locked up and twisting the base section as the lid closes instead of rotating at the hinge point.

Great info. I’ve got some lubriplate that is pretty durable and isn’t impacted by water. I think they make something even a bit more durable than that.

Either that or wheel bearing grease.
