Vibration In 2005 Tahoe

[brodie25]

I have recently adjusted my torsion bars on a 2005 chevrolet tahoe z71 to put 285s on my truck. Since I haved done this I have a terrible vibration in my truck, the ride is pretty good until 45 mph then the steering wheel starts vibrating terrible and stays like this until I get to about 62 mph and it levels back out. We have rebalanced the tires and they are ok. We even put a set of tires on off the lot from a new truck and still the same thing. I had alignment and everything done, so I am now stuck. Any Ideas?

sounds like something up front is worn out

we replaced a lot of parts in the front end due to not being able to align it and bolts froze up. Tie rod ends were worn out
