Tom,
There is a right and left on my 99 lugs. Chappell
Hmmm, back in San Antonio last year when I had the rear tires changed the guy removing the tires broke 3 or 4 on the drivers side. I had them replace all on both sides thinking they might have been stressed. Maybe the guy didn't realize they were rightie loosie, instead of leftie loosie?
We had same problem on ours when we got new tires.
