If I have two tables that I want to synchronize via replication publish
subscriber model and they don't contain primary keys i.e. an ID field, but
there are three columns that make a unique key. The tables are HUGE so I
want to minimize down time.
Can replication still be done, either snapshot, transactional, or merge?
Again I don't want to create any more columns in the tables because of the
record volume.
Thanks

I don't know about the replication part of your question, but why not
simply add a composite primary key on the three columns? If that's what
your data model looks like, then the key should be there, or at least a
UNIQUE constraint, if you need to use an artificial key for some
reason.
For replication issues, you might get a better response in
microsoft.publi c.sqlserver.rep lication

Adding a primary key would be the best, but it is not an option.
The table volumes are huge and I was hoping that SQL Server replication
would manage all the uniqueness of the tables to be replicated. I was
reading that there may be away to do this type of replication.

I don't know how their uniqueness is stated today, but I assume that
the index is created as unique?
It's possible that replication gets by with unique index, but I
would not be surprised if a PK or UNIQUE constraint is required.

It may be that your local newsserver does not carry this group for some
