The van (2007 Express AWD) has been riding a little floaty lately, and there is an occasional rattle at the front. So during an oil change a week ago I poked around at the front suspension and found this. It's the same on both sides. I installed these last year and I thought I had them tight enough. I think the Titus Canyon east approach road did them in, but I can't be sure when I noticed the floatyness. So I put new bushing on and tightened the nuts down about 3/4". Until the bushings were snug with a very slight bulge. There is no lock washer on (shocks didn't come with any) them and I did not use any lock tight. That's what I did the first time I installed them. Is this going to happen again? Am I missing something? Anyone ever seen this before? I got a 3000 mile road trip coming up and I'll be watching them, but I expect I'll be getting rapid bushing wear due to the holes in the shock mounts being reamed out from the shock stems floating in them for a number of miles. Over the years I've installed a lot of shocks and never had this problem.
