At a loss involving vibration

I would look into rebalancing the tires. A co-worker of mine got ne Hankook Dynapros and had to go back 3 times for rebalancing, and this was to a reputable shop.
The tech running the machine could have had an off day or you could have thrown a wheel wieght.

 

i would like to see what your caster is set at. out of wack caster wont cause tire wear, but maybe vibrations at certain speeds? just curious.

 

I honestly thought about caster. That would explain my steering wheel not returning to true north after a turn quickly or efficiently.Could also explain why my handling sucks a bit.

But yea, vibes are back and consistent now. Always 60-67 mph. thats it. Clock 70 and things smooth out quick. Who the hell knows.

It sure isnt the duncrap tires. Im running firestone destinations now.....hmmmm..my thoughts?

Possibilities:

1.Caster (has to get fixed anyway)
2.Shocks (WHICH PASSED BOUNCE TEST)
3. Bushings
4. Bearings (no noise,.....yet)
5. Steering Rack
6. Some random issue....

My solution. Gonna wait till I get the truck back in september to outflank this problem since ill only have the truck for 2 more weeks since i leave for basic....
