Yes. I don’t think I’ll use those anymore. Even my suspension bushings wore out in less than three years. For the motor mounts they’re probably a little too stiff. I don’t know.

So, the original question-is it stupid to trust a used ecm from a junkyard. Or could it be inspected to see if any usual trouble spots exist?

Without opening it is a lottery. Knocking on it will reveal issues in the later stages only.

Myself I would look for manufacturing date, if it is on the sticker or somewhere. If ecm is not old and can be had for good price it makes sense to buy it as a spare to keep in truck.

Where I live most bigger truck and car dismantler have their items all pictured up and listed online, just search for part code and find the latest made one. Usually electronic parts are priced upon part code, not year on sticker.
