thanks,
150k miles, 3.0l
Michelin Latitude 235/65R17 ( wanted factory Energy MXV4 - dealer said they are discontinuing Energy said the latitude are comprable - they are fine except about .5 less mpg). Balanced on standard "tire shop" machine. Weights were hammered on inside of rim edge rather than the stick on weights (I like the hammer on better, have lost some of the stick on's in the past)
standard rims
shocks very recent replace, control arm replaced 75k miles ago.
More of vibration "sound" thump than a "feel" thump

Got me thinking.....they didn't pull off any of the old stick on weights, just added what was needed. Going through a tough winter, extreme cold could have kicked off some of the stick on weights???
