GL350 rear pads wearing uneven. Outer pad wears first

I searched, can't find my answer.
Seems odd that the outer pad would wear first. Piston side is usually the one that will wear if the guide pins or something is sticking. No such thing here.
These pads have less than 10k on them. I don't tow and my wife mostly drive it. (Read easy driver.)
They are Pagid pads. Outer is gone and inner is half worn, maybe.
Any ideas?

Step 2: Be aware of outer pad wear. For this wear pattern, the outer brake pad has much less material than the inner pad.

This type of wear is caused when the outer brake pad continues to rest against the rotor, even when the caliper is released. This is a sign of malfunctioning guide pins, bushings, or slides. The easiest way to fix this problem is to replace the caliper and the brake pad.

Thanks!
Seems like the pins are fine. Also, both side are doing the exact same thing. Seems odd as well.
May just get new calipers.
