I have a shake at highway speeds that new tires don't solve. It's not terrible, but I am getting tired of it. Any thoughts? Could all my rims be bent or something? I have American Racing aluminum jobbies on there.
I can't seem to find the source. The track it good, alignment is good, no cracks in the frame, new u-bolts on the front axle.... King pins "seem" fine.

 

I think I read recently that axle u-joints have played a roll in some vibrations.

 

I hear that the new road force balancing technique gives much better results over the dynamic balancing. Might be something to look at.

 

Mine seems to vibrate a little more with my same tires on some newer rims that were dynamic balanced, not enough to bother me but its a hair different it seems. I'd check all U-joints too, one of my rear ones let go and it didn't sound good and vibrated at certain speeds.

 

Does this happen with the front hubs in the "lock" position?
Hubs locked or unlocked with tranfercase in 2wd or 4wd?
Mine vibrates but only when the hubs are locked.It gets even worse if I'm running in 4wd.
I know my slip yoke on the front shaft is a little wore and figure that's where mines coming from but I'm goint to pull the front d/shaft and check the double cardon joint for wear as well.
Just a couple of options.
