now that I have your attention,

I was hoping to find someone who would help me out with finding a fine high speed vibration problem on my truck. around 70 and up MPH

I could really use the help of someone to volunteer swapping their wheels/ tires to my truck (any size combo) to see if the problem im having is My wheels and tires... or i need too keep looking and spending $$$ i dont have

i want to see if my vibration goes away with other wheel tire setups (my tires/ wheels are in rough shape)

obviously a tire store wont do this w/o buying them
thanks for any help in advance

unable to find a Oregon/ potland chapter
of course youll have a short case of beer!

 

do you have a 2 piece drive shaft? tires would usually come in (start to vibrate) at slower speeds

 

check your u joints and carrier bearing

 

i would check to see if the weights come off drive shafts or tires check if belts spreaded

 

no, 1 piece (no carrier bearing) (short box)

replaced main drive line u-joint.. fixed that separate vibration
im trying to do the cheapest/ free methods first front u-joint SEEM ok but well see

possibility, that why im tying to borrow someones tires/ wheels to eliminate that possibility.

 

I have it too with my BFG right at 65 mph (probably 70+ as my speedo isn't calibrated).

I have a spare bfg/h2 wheel that is brand new, so I spent several hrs moving this spare around and test driving to find the specific tire that was out. Of course it was the 4th tire which made the biggest difference yet I still had a slight vib at 65+. I took this tire and wheel to schwab and they put it on their balance machine and let me watch it spin. It wasn't really out of balance but did wobble horizontaly on the machine. They said there isn't anything they can do to fix it. My vib at 65+ isn't really that bad and I figure that if all 4 tires have a slight out of round wobble, then this is as good as it's going to get.
In reality, my 65 mph is faster than most people drive (as my speedo isn't correct), so I can just slow it down and its smooth sailing.
