Ya you should tighten it up, might as well clean them both up and tighten them while they are both out. And maybe consider getting the shocks fully rebuilt on one of the skids. Cost me $320 for all 4 shocks.
When I bought my srx, pretty much everything was shot! I rode it the first year with only a tune up pre-season and got pretty lucky nothing went wrong all season. But last year I had the shocks rebuilt and it was night and day difference! The guy who rebuilt the shocks said that they've probly never been rebuilt...they were completely shot.
Just something you may want to consider having done.
