If the steering wheels is wobbling with 2 different set of tires it sounds like your problem is in the front end, a vibration in the rear of the truck is normally felt in your back-*** area. Your issue sounds like a worn front end part or maybe one of the rotors lost it's balancing weight, or a bearing adjustment issue. The easiest way to check for a out of round tire is at a very low speed in a big uncrowded parking lot, let go of the steering wheel, if something(rim/tire) is out of round the steering wheel should rock back and forth.

 

Where are the balancing weights on rotors? Never heard of them before.. Yeah i thought ball joints or bearings maybe even though theyre new but all seems tight for steering up front.. Ill try tht out tonight! Thank you, ill get back to you and tell you what happens.

 

They are welded in the cooling fins, a wobble describes a side to side vibration-more like a front end issue. Wish I could drive it for you toget a better idea of what you're feeling.

 

Yeah deffinitly a front end issue i think and well where do you live? Im in british columbia

 

It seems to do it more when cold out, weird but drove to work started out real bad on the hwy then got better when truck warmed up and now thats its 30* C out on my way hone its the same as when it was warmed up on the way to work. Odd for a steering problem, i took a vid of it when it wasnt bad, very hard to see the shimmy but its there. Gonna try the parking lot idea at night when theyre empty. The video is as good as the shimmy gets, usually a lot worse varying from 1/4" to 1/2" back and forth and video is like 1/16".. Will upload shortly

 

on youtube..

very hard to see sorry, but hope it helps a little.. ill try for one when it shakes worse!
friggen sideways too! sorry phone always does that

 

Just a thaught in passing when you checked your front suspension did you look for loose or mising bolts that hold the steering box to the frame? also the frame its self is prone to cracking around the steering box mounting area. Have someone "saw" the steering wheel back and forth and look for movment of the box in relation to the frame.

 

Tried the parking lot test and the wheel stays in place doesnt do anything on level ground at slow speed i will be checking for cracks and loose bolts and play in steering box area tonight after work.. Took another video thatight be easier to see. Will get uploaded shortly

 

No visible problems with the steering linkage area, gonna toghten every bolt upfront tonight. From rack n pinion mounts to a-armsand make sure all bolts to do with steering and suspension are good n tight up front. No easily visible frame problems either but a snall crack would be real hard to see so.

 

Videos of it a bit worse
