todays update:
dropped the truck off this morning, the guy said they put the miles on the truck test driving it and sometimes put as much as 100 miles on them for problems like this to be sure they fixed the problem.
yet they keep saying they don't feel it anymore and its fixed when its not
as to the hubcap trim ring, the parts guy showed it to me in the computer and the rim asnd trim ring are one unit in two pieces that are bonded together at the factory so they don't come apart separately and that's why the weight was put on the outside but they will send it back and have them rebalance it with only putting weights on the back side so it doesn't show on the outside.
on the way in today I noticed a wheel hop issue at 40 mph and the service guy admitted he felt it too but he said that's just how short bed trucks do because of the suspension
. I explained the truck did not do this before with the other set of tires they had on the truck at first and in fact all I ever owned was several new short bed trucks and they don't bounce or hop unless the road causes it and on smooth flat even roads with fresh blacktop there will not do that just because of tight suspension.
left with rental truck again and i'll see what happens this time.
repair #3 for the same vibration problem is in progress
