BTW, at 186K miles I think my ball-joints were due - both were extremely loose, and the passenger side had roughly 1/8" of vertical play in the stud. I have a friend with an '06 who replaced his at roughly 205K - and reported almost 1/4" of vertical play in the studs. If you have similar mileage you may wish to consider checking them or having them checked and/or replacement. He and I both probably should have replaced them at 150K. Outer tie-rod ends were still tight (maybe another 50K to 100K left in them)
What's the ball joint replacement spec? I've looked & asked for, but haven't seen one. I've been going on tire wear pattern figuring if the tires are wearing evenly & smoothly, the suspension is OK.
