I've got the 2 1/2 turbo looking ones, the first one starte to rattle at about 7,000 miles and the second about 10K. The truck has always been primarly driven on smooth pavement so it's not like they were shaken loose going over washboards. It shouldn't really make any difference but they are on my 507 Cadillac powered El Camino.
