wobbly kitchen Table - from 2 to 3 legs

I'm a third legger....did it last year and what a difference! Ordered an identical unit to the others (even came with screws) from the factory.

Those post-style legs will always loosen because most folks lean on the table, causing the post tubes to deform slightly. After the second post broke, I installed a pair of folding table legs. They were about $20 at a local big-box store. Now, the table is rock solid and, if I wish, the whole table can be carried outside to use there. Since my table top also is part of a bed platform, I had to make sure that with the legs folded, I was able to place the table top in it's bed position. That was easy to do.

One of my previous trailers had that problem. I flipped the legs up side down and re-inserted them and the problem was solved.

It seems like the post have wiggle room in the bases. It does not appear to be one leg longer than the other. Its a 3"3/4" tube in 4" opening. (axp)

These are a possiblity but I don't know if they have that much adjustment: Leg levelers

My inclination would be to:

1) Shorten the long leg--might have to do that at the top where it joins the table.
or
2) Lengthen the short leg, again near the top. You might have to fab a metal bracket.

It's hard to say much more without seeing this table. It's hard to understand how it got that much play in it.
