Guys,

I'm having some serious vibration issues when I get up to the 50-65mph range.

I've had the front bearings recently repacked, the tires rotated and balanced (not on the vehicle), the front end alligned, the Bilstein shocks that I have on are less than two years old and appear to be in very good condition, and there's no unusual treadwear on any of the tires (BFG AT with approx. 18K miles on them).

Any ideas where else I can look? Should I find some one who will balance the wheels on the truck?

 

Sounds to me like a wheel balance issue.
Last year I paid to have mine balanced on that expensive machine made by Hunter.

A weight flew off on the way home, and at 45 MPH my steering wheel vibrated real bad.
I went back a few days later and they fixed it. I was still not impressed.

I get the standard wheel balance at Les Schwab Tires with the weights on the back only (weights on front look fugly) and I don't have hardly any vibes now.

I get a little sometimes, but that is due to the nature of the M/S tire, and not the wheel balance itself.
I'd try another shop and see what happens.

 

I had a similar problem and it turned out to be the U-Joint and the bearings in the rear differential. I took it to the mechanic and he replaced them and all is well. My vibration only started around 45-50 MPH. Maybe check that out! :fireman:
