Hi Dave,

I got a set of 4 used front hinges and the detent cams were badly frozen.
I couldn't budge them by hand at first.
The cam wouldn't move in the vise using large vise grips on the hinge.
After flushing with solvent, liquid wrench and MMO they finally moved.
You can loosen them with slip joint pliers from the top.
It looks like the cams had rusted to the bracket.

The driver door hinge has the most wear as you would expect with very little wear on the detent spring.
There's much less play in the cam so it's the one I'll use.

Make sure the detent cams turn free.
If they freeze up in the car, the cam detent will start cutting the spring.

Is it possible to replace the lower hinge without removing the door?

Thanks, Bill
