Tie rods. Ball joints. Axle pivot bushings. The bushings that mount the front of the spring to the frame. All moog except the frame to spring bushing. I've only had the truck since January so they dont have that many miles on them.

 

Rotate the tires front to back, check your tie rods. Try bringing it to a tire shop that can check the steering parts. Tell them not to fix anything just pay them to look it over. Get a price for just checking it out. Most places will do that for cheap. Most of the time they will tell you what is wrong.

 

Maybe the bolts on your cross over support for the transfer case. or cracked frame.Just guessing, hope it helps.

 

almost sounds like you have a broken belt in one or both of your front tires!

 

how much weight are on the wheels?(wheel weights not total weight)

 

My 1995 did the same thing . Shake so hard it would almost throw you off of the road . This was what the deal was . The tie rod ends went bad and this caused the tires to wear funny when the tie rod wouldnt do its job holding the tires straight . After the tires wore like they did it would cause them to shake violently especially when driving on the hwy . Replacing the tie rod ends fixed the cause of the problem , however, the tires were still shaped funny and would continue to shake while driving . A friend of mine told me what it was b/c I was complaining about overhauling the front end and still having the problem . He suggested that I swap front tires and see how that affected it . I did and the problem went away .

 

could just be our crappy utah roads!lol

 

I very well could be!!! I'll rotate the front and rears and see what happens. The father in law has some 36" mickey t's maybe I'll have to steal em from him and see what happens. I dont know how much weight is on them? i'll have to count it up
