Default Re: Why no lock-washers?

Two thoughts..

First as mentioned, the heat cycling and the type of metal used for a lock washer would not work.

Second, not needed. I would guess that Ford used tight tolerance threading here also. So the nuts would be kind of snug.

I do not know if those are the right answers, but I am guessing that Ford had a good engineering reason they were not needed.
